Backyard Greenhouses Extend the Garden Season

Every year my dad (Ron Simmons) starts many annual plants for our family in his backyard greenhouse. I get most of my flowering annuals, vegetables, and herbs from dad’s greenhouse. His plants are amazingly healthy and grow better than any other plants in my gardens.

Dad's greenhouse

I see more and more hobby greenhouses and hoop-houses popping up in homeowner’s backyards. What’s the difference? They are both very similar. They both extend the growing season in spring and fall, sometimes allowing edibles to grow year-round. Both hold in the heat with a covering, usually plastic. Greenhouses typically grow plants on benches or tables, while hoop-houses grow plants in the ground. Greenhouses usually have a supplemental heat source, while hoop-houses trap the sun’s heat inside to warm plants in the ground.

Dad's greenhouse

Due to their relative low cost, hoop-houses are becoming more popular than greenhouses. Hobby greenhouses costs vary from several hundred to several thousand dollars. Operating costs can be high if year-round heating and cooling are required. Greenhouse kits are probably the easiest way to get started, or like my dad, you can design and build your own. Dads’ greenhouse started with recycle glass windows, but due to hailstorm damage he later replaced those with greenhouse polycarbonate panels.

Most hobby greenhouses grow plants in soil, but hydroponics and aquaponics are also options. Hydroponic systems grow plants in nutrient enriched water, instead of in soil.

On a recent trip to Monterey California, I visited a small community garden on the campus of the Middlebury Institute of International Studies where my son Derek is going to grad school. The garden had a small aquaponics system in the back where fish are raised in tanks that supply nutrient rich water to hydroponically grown plants. When I was there in April, they were growing lettuce, Swiss chard, and onions.

Backyard Greenhouse Basics was the topic of a University of Illinois Extension Four Seasons Garden webinar series. Extension Horticulture Educator Kim Ellson explained how, regardless of their shape or size, greenhouses allow us to get a head start on our favorite plants and be outside whilst the weather is bleak.  Kim discussed how to get the most out of your backyard greenhouse.

If you’ve dreamed of having your own greenhouse, let this be your year to make that dream come true. In just a few years, the savings from growing your own food will pay for the greenhouses.

Green Space is Necessary for Life!

Are plants just pretty or do they really make our lives better? Look around you the next time you drive through town. Are there enough green spaces around your community? Research has found that plants are beneficial to our health and psychological wellbeing.

University of Illinois researcher Bill Sullivan, Associate Professor of Horticulture, studied these issues. Dr. Sullivan’s research addressed the question, “Does having everyday contact with nature affect a person’s functioning?” That is, is there a connection between the presence of nature and effective human functioning?

Frances Kuo and Bill Sullivan of the University of Illinois Human-Environment Research Laboratory studied these concepts in Chicago’s Robert Taylor Homes, the largest public housing development in the world. The Robert Taylor Homes consist of twenty-eight 16-story apartment buildings. Most of the complex is an urban desert – concrete and asphalt cover the spaces between the buildings – but there are pockets of trees here and there. Kuo and Sullivan studied how well the residents of Robert Taylor were doing in their daily lives based on the amount of contact they had with these trees.

The study found that when compared to people who live in places without trees, residents of Robert Taylor Homes who live near trees have significantly better relations with, and stronger ties to their neighbors. Trees are important. Frances Kuo put it well when she said, “Before we started our research I would have said, trees are nice, but the problems we’re facing in our cities and our budgets are such that I’m not sure it’s worth it.” “I think that through this research I have become convinced that trees are really an important part of a supportive, humane environment. Without vegetation, people are very different beings.”

For more information visit the Human-Environment Research Laboratory website. The information is certainly applicable to smaller towns as well.

Plants in my home office be a window that
looks onto the plants in my backyard. 

But plants are just as important indoors too. Plants are an integral part of our homes, offices, and shopping malls. This is not just a fad. Plants serve a purpose in these places by filling a psychological need, enhancing our environment, and are also a satisfying hobby. But more than that, indoor plants help cleanse the air! A study done by NASA investigated the potential use of plants as reducers of indoor air pollution on Earth, and in future space habitats. They found that certain plants not only clean the air of pollutants, but also reduce airborne microbial levels and increase humidity.

Research in these areas will continue at the University of Illinois and beyond. For those of us who love plants, the results are not surprising. Plants are a necessary part of our lives!

A New Direction Riding a Tiger in California

After many years of road touring my husband and I decide to go a completely new direction and get an adventure motorcycle, trading our 2009 CVO Ultra Harley for a 2020 Triumph Tiger 900 GTPRO, with an added 52 Litre Trekker Top Box. The Tiger fits in the 6 1/2-foot bed of our Ford F150 pickup truck and allows us to explore more remote locations. Compared to the Harley, I am a more active passenger on the Tiger, comfortably experiencing more of the ride (and more locations) than ever before. 

Our month-long stay at an Airbnb in Morro Bay is the perfect place to trial the new bike. Here we are close to our sons and many outdoor recreational opportunities. For us, this is a great way to safely vacation during the COVID pandemic. 

Although the California Butler Motorcycle Maps provide us many great riding options, it is the impromptu suggestions from local adventure riders that send us new directions and on our best journeys. Follow our route described below on this Google Map link.

Another Triumph rider at the gas station near our house said one of the best road rides in the area is State Route 41 between Morro Bay and Parkfield. Route 41 is a smooth paved road that winds through avocado and olive groves. Between Atascadero and Creston, we witness amazing vistas, including steep straw-colored pastures and dense groves of trees. Just past Shandon we turn down Cholame Valley Road towards Parkfield. On this paved, but bumpy road we ride through farm fields on either side, while trees dot the hillsides farther away. 

"Jerry's Corner" on the San Andreas Fault 

At the end of the straight Cholame road, we meet another biker on his KLR 650. Jerry enthusiastically informs us that we are stopped right on the San Andreas Fault line and suggests several area roads to explore. 

We follow Jerry’s advice and wow! We ride through the quaint town of Parkfield, which has eclectic, fun looking – but closed - establishments that we need to visit once COVID is over. The Parkfield-Coalinga road winds us up into the mountain. As Jerry warned, the road turns into the hard packed dirt of the Parkfield Grade with incredible mountain views. The Tiger’s off-road mode performs perfectly, providing grip and traction on the steep, dirt road. Although the road is uneven with occasional debris, the Tiger absorbs the bumps well for both driver and passenger. The steep slopes and hills below us look like velvet shining in the sun, with shades of tan, green, and blue.

Parkfield Grade

As we climb higher in elevation, the scrubby trees turn to taller evergreens, with large pinecones covering the road in places. We pass many cattle gates with open range cows grazing along the roadside. At Route 198 we stop at a roadside pull-off for granola bars and water. Although the weather was warm and sunny until this point, from here we have a windy, cold ride on U.S. Route 101 back to Morro Bay. The Tiger’s instrument display records the day’s ride at 195 miles, over 4 ½ hours, averaging 42 mph. 

Jerry also suggested we ride Peach Tree Road, so we head back there another day. This time we take Old Creek Road from Morrow Bay to State Route 46, which passes through Paso Robles wine country. Grapevines fill our view on both roadsides. In San Miguel we stop for pictures at the mission, then take Indian Valley Road to Peach Tree Road.

San Miguel Mission

At this point the landscape turns to cow pastures on treeless, steep slopes with short sage-green plant cover. Well-rounded hills roll one after another, often looking like camel humps. 

Peach Tree Road

Peach Tree Road is a paved road that climbs along the San Andreas Fault line. At the top, we stop for a snack and water break. Three other adventure bike riders and a farmer ride by, but otherwise we are all alone. It is so quiet here, with the birds serenading us as we soak in the beauty around us. The fault area is a steep cut in the ground with a small stream and a flat grassy area near the bottom. 

Peach Tree Road takes us to State Route 198, which we ride back to Parkfield Grade. Riding the other direction this time, the Grade’s pavement is rougher and the dirt road bumpier than before. The Tiger’s off-road mode helps some, though there are a lot of “wash boards” in the dirt. We snake up and around the mountain and down again, all next to a steep edge. Some of it is good scary and all of it is spectacular. At one point a cow calf on the road stares at us as we ride by. 

Parkfield Grade

After passing through Parkfield again, we stop at “Jerry’s corner” for a snack rest before finishing the ride home. This corner is by a creek with a nice blend of large oak trees and open pasture. We watch many birds there, including red tail hawks mating, cute little acorn woodpeckers, magpies, and a bald Eagle souring overhead. 

On the way back to Morro Bay via Route 41, we stop at a Taco place outside Atascadero for supper. It has COVID safe, outside dining and the best chili-relleno I’ve ever eaten. All in all, another great moto day riding 189 miles, almost 5 bike hours, averaging 38 mph. 

Our new Tiger motorcycle is the perfect addition to our retirement travel adventures. In the past, we’d often been at a road intersecting gravel and pavement and wondered what’s down the gravel road. This adventure bike takes us a new direction, down dirt and gravel roads, where we see breathtaking views and experience exhilarating rides. We can’t wait to see what direction our bike will take us next.

Green Plants Improve our Health

St. Patrick’s Day reminds us to look for green. Green is the color of peace and serenity and important for our psychological wellbeing. Plants play a big role in filling that psychological need. Much research has been done on the importance of plants in our lives.

Have you ever noticed how people choose seats next to plants when given a choice in malls or parks? Our world is busy, and we are constantly bombarded with noise, movement, and chaos. Plants help relax us. Because of their simplicity, plants, or natural scenes, reduce physical and mental excitement and improve our health.

Research has found that in offices with plants, employees are more content and comfortable. Plants in an office result in higher office morale and less absenteeism. Employees exposed to plants were more creative and productive. This, in part, is why you find plants in most business settings and other interior settings. The federal government has strongly endorsed the use of plants as an integral part of office interiors.

Shamrock plants in the University of Illinois Conservatory

As St. Patrick’s Day approaches, remember how important plants are to our psychological wellbeing. A popular St. Patrick’s Day plant is the shamrock. Although there are several types available, the most popular is the Oxalis due to its shamrock leaves. The leaves are in threes, with each individual leaflet 1½ to 2 inches wide. Available with purple or green leaves, this plant is easily grown for table tops or hanging baskets. An added plus is the white or pink flowers that open in winter and spring and continue all year round with sufficient light.

The shamrock plant is a bulb or tuber. After flowering, leaves may die down and the tubers benefit from rest in drier soil and cooler temperatures. As new growth resumes, move it back to a warmer location, increase watering, and resume fertilizer applications. The plant prefers bright light without direct sun.

At times I have seen other plants sold as shamrocks. These include ordinary lawn clovers, weedy oxalis plants, and other clovers. However, the shamrock described above is the only one that makes a nice, long-term houseplant.

Another good green St. Patrick’s Day plant is the green carnation. These are white carnations dyed green. Use them in a vase or as a corsage. These are usually readily available this time of year. If not, you can easily dye a carnation green by letting it drink green colored water. White flowers can also be painted green with special floral paint.

Happy St. Patrick’s Day!

Gardening with Kids

Gardening is for everyone but is especially important for children. I cannot over-emphasize the importance of gardening with kids. It encourages personal growth, environmental stewardship, hands-on learning, improved nutrition, community involvement, and family interaction.

During my 25-year career with Extension I’ve attended many programs on how to garden with kids. Each time I come away even more convinced that every child must have an opportunity to do hands-on gardening. It is vital information they will use for a lifetime.

My sons had fun gardening in our yard. 

Make gardening fun! Here are some ideas to consider.

• Play detective and investigate the site. Look for sunny and shady spots. Dig in the soil and discover its characteristics. Run water and watch where it runs away or sits.
• Do an art project to draw out the planting. Have them measure, graph, create shapes, and count outside. 
• The fun part is preparing and planting. Let them do it! Granted, it might not be perfect and it might not be the way you would do it, but to a child it is great.
• Maintenance sounds dull and hard to most people but make it a game. Play a watering race using spoons, cups, watering cans, and the like. Go on a weeding mystery mission to find the “dreaded bad weed of the day.”
•  Develop awards for the best flower, vegetable, weed-free bed, etc. Let everyone win!

Want more ideas? There are many reference books available for reading by adults and children. There are storybooks for children, videos, smart apps, and computer programs. Have kids join 4-H and do one of their many plant-related projects. Search the Internet. University of Illinois Extension has several interactive horticulture sites for kids, including The Great Plant Escape, The Adventures of Herman (the worm), Let’s Talk About Insects, Secret Life of Trees, and Trees Are Terrific.

Teach kids about plants. While doing so, we will teach kids fundamental science principles that are necessary for life.

Earthworms ...Not just good fish bait

One of my fondest childhood memories is dew-worming with my Dad (Ron Simmons). We’d go out at dusk with a red lighted flashlight, sometimes after Dad had watered an area earlier in the day. I don’t remember ever buying worms; we just “harvested” them ourselves. Even as a child I learned the best way to grab a worm without breaking it before it escaped back into its earthly home.

Dad and me fishing on Anderson Lake

Most people know that earthworms (also called night crawlers) are very beneficial for our soil. They daily consume their weight as they grind large organic materials into smaller ones. The University of Illinois Extension Herman the Worm website) calls the earthworm “one of nature’s top soil scientists.”

Worms benefit the soil in many ways. The add air and water, which produces a perfect growing environmental for most plants. They essentially “turn” the soil as they bring organic matter down and mix it with the soil below. When they eat, they leave behind castings that area very valuable type of fertilizer. The equivalent of about one third pound of top-grade fertilizer is produced per worm each year. As the website says, “Having worms around in your garden is a real good sign that you have a healthy soil.”

A fact about earthworms that most people don’t know is that they are not native to North America. Early European settlers brought them here during the 1600’s and 1700’s. They tagged along in the soil of plants brought from their country. Fortunately, this foreign critter has proved to be mostly beneficial.

Here are some other interesting facts about worms. In one acre of land, there can be more than a million earthworms. The slimy excretion of earthworms contains nitrogen, which is required for plant growth. Baby worms hatch from cocoons smaller than a grain of rice. Worms don’t have eyes, but they can sense light (which is why Dad and I covered our flashlights with clear red covering). The number of rings or segments of the body is species dependent: the common earthworm has about 150 segments while the red worm has about 95.

Obviously, worms are an important component in any composting process. An increasingly popular form of worm composting –vermiculture –uses worms to turn kitchen scraps into compost. It is easy and cheap. This process uses a red worm, not the larger earthworms. Take a plastic bin with holes drilled in it, newspaper, soil, worms, and fruit or vegetable peelings and you’ll soon have “black gold” to use in houseplants or outside.

So, the next time you thread a worm onto a fishing hook, remember that they are much more than fish bait. Good luck fishing and Happy Father’s Day!

NOTE: Since this article was written, the invasive jumping worm has been found in Illinois. View this Invasive Species Alert: Jumping Worms for more information. 

The Bald Eagle

Today (2-2-2002) is Eagle Days in Havana. Numerous eagles spend their winters right here in central Illinois. Many can be easily seen from Riverfront Park in Havana. If you’ve never seen a Bald Eagle in the wild, I encourage you to take a drive to Havana this morning.

On January 13, the Champaign County Audubon Society did its annual Eagle Count along the Illinois River from Havana to Beardstown.  They counted 206 Bald Eagles (95 adult, 111 immature) and one adult Golden Eagle.  The Golden Eagle was at Emiquon refuge across the river from Havana.  There were also lots of Bald Eagles at Lake Chautauqua, just north of Havana, where there were also thousands of Canada Geese, many Snow Geese, and 21 Swans.

My family has really enjoyed watching Bald Eagles this winter. I find this really awesome especially knowing that the eagles came very close to extinction. The story of the Bald Eagle comeback includes an important lesson for us all. 

The Bald Eagle was originally classified as endangered in 1967. Shortly after World War II, the use of chemicals such as DDT and other related compounds (including Chlordane) became widespread. These chemicals last a long time in our environment and started to accumulate in Bald Eagles due to their natural feeding habits. The DDT impaired the eagles’ eggs, resulting in thin eggshells and reproductive failures. Since that time, the US-EPA has banned such chemicals and conservation and breeding efforts have brought our national bird populations back.

I tell you this because I think it is a great story of how humans can fix a problem we created. Think of this story each time you use a pesticide. Pesticides are anything used to control a pest and include insecticides, herbicides, fungicides, etc. Almost all of us use them. When you grab the ant killer under the kitchen sink, you are using a pesticide.

To assure you apply pesticides in a safe and effective way that will obtain the control you want and still protect your family and our environment, you simply need to read the label. Reading the label is extremely important and it is the law! Labels change frequently, so you need to reread them each time you use the product. Carefully follow all directions on that pesticide label.

Whether you use pesticides or not is a personal decision, but if you do use them with respect and READ THE LABEL!

Worm Composting

Composting is not just an outdoor activity. It can also be done indoors to get rid of those food scraps in your kitchen.

Worm composting involves using worms to turn food scraps, newspapers, and cardboard into a rich compost, which can be added to potted plants, lawns and gardens. It is convenient, and you can do it indoors (even in apartments) or outdoors.

Don’t worry! When done correctly, worm composting will not cause an odor or have worms crawling all over your house. The worms are quite small, but could still be used for fishing.

Worm composting (or vermicomposting) is one of the easiest methods for reusing fruit and vegetable scraps from your kitchen and yard. All you need is a container filled with moistened bedding, worms, and food scraps.

Even in cool winter weather, where outdoor compost piles lie dormant, you can compost your food scraps indoors with worms and reduce the volume of your household garbage by as much as 25%. The end result is unsurpassed as an organic soil builder and plant fertilizer, containing high amounts of nitrogen.

Worm composting is easy, rewarding, and fun! Given the right environment and a little routine attention, a handful of worms will multiply rapidly and digest your kitchen scraps.

Worm composting is a great way to recycle food scraps indoors all year long. 

To learn more about vermicomposting make sure to read Oregon State University Extension’s “Composting with Worms"

New Plant Hardiness Zone Map in 2012

This has certainly been an unusually warm winter so far. Many people are concerned that the warm temperatures will results in plants sprouting too soon or in heavy summer insect problems.

Some people wonder if our climate is changing due to various factors, including global warming.

Source: Illinois State Climatologist  

The USDA released their new Plant Hardiness Zone map recently. The 2012 changes show that we are indeed experiencing overall warmer winter temperatures.

The USDA hardiness zones are based on average winter minimum temperatures. According to Jim Angel, Illinois State Climatologist at the Illinois State Water Survey, “This is certainly an improvement on the old USDA map that was based on data from a relatively short and cold period from 1974 to 1986.” Angel says that the new map is based on a longer period that includes the milder winters of the 1990s and early 2000s.

The new map can be found at http://planthardiness.ars.usda.gov.

To reflect these milder winters, most zones have shifted northward. Angel says, “Here in Champaign I used to be in the middle of Zone 5 according to the old USDA map. Now I'm almost in Zone 6.”

These maps are a useful guide. Most garden catalogs list the hardiness zone rating for their plants. The hardiness zone is an important plant selection guide, but it is only one factor in determining if a plant will survive the winter. Other factors, such as moisture levels and critters (voles, rabbits, and mice), also affect a plants chance of winter survival.

Speaking of critters, will this mild winter affect insect populations this summer? According to Phil Nixon, Extension Entomologist, mild winters or cold winters have little effect on the number of insects that people typically notice.

Nixon says that it is true that in a mild winter, more pest insects survive, but so do more predatory insects, parasitic insects, and other natural enemies. Contrary to popular belief, Nixon says that the most important impact on insect numbers is spring weather. Cool, damp springs encourage the development of fungi that attack insects and slow the development of insects. The result is fewer caterpillars and other insects surviving through the spring.

And finally, if you have daffodils sprouting or plants leafing out early, don’t fret. Although some of the early growth could experience freeze damage later, the plants should be fine overall once our official spring finally arrives. You can add a layer of mulch over the sprouting plants to provide additional winter protection, but it is probably not essential.

Removing Tree Stumps

Recent droughty summers, a cold winter, and various other environmental and pest problems have killed many trees in our area. Usually when a tree is removed a stump is left behind. Here are several suggestions on how to remove tree stumps easily, quickly, and economically.

According to Bob Frazee, retired University of Illinois Natural Resources Educator, the cheapest and easiest method of removal, although not the quickest, is to cut the stump at or below the ground level, cover it with soil, and keep the soil moist. Decay organisms will then rot the wood. Grass may be planted in the soil if the thin layer over the stump is kept moist during dry seasons. The decaying method may be hastened by boring several vertical holes in the stump before it is covered with soil. This method may be used any time during the year. 

Frazee says that stumps may also be burned out. However, before burning stumps, be sure to check your local ordinances to see whether open burning is permitted. Frazee suggests that stumps may be burned out rather quickly with charcoal or coal by making a “stove” from an empty 5-gallon metal container. A stove is made by removing the bottom and top from the can and punching 4 to 5 one-inch holes in the side near the bottom. Place the stove on top of the stump and build a fire in it. A hot fire is required to burn out stumps, since the wood absorbs moisture from the soil and burns like green wood. Stumps will burn best during dry seasons.

Grubbing or digging out stumps is another option, according to Frazee, but it is hard work. Stumps larger than 15 inches in diameter are usually rather difficult for the average person to remove.

A popular option for homeowners to explore is use of a commercial stump grinder. Mechanical stump grinders that chip the wood are available from some landscaping firms, tree removal services, and some community street departments. A stump-cutting or grinding machine is often the quickest and most satisfactory means of removal. It can chip out a stump to 8 or 12 inches below ground level in minutes.

Stump removal is not easy. Many people resolve to leave the stump and let it decay naturally. Chemicals are available that can help speed up the decomposition process. Instructions for stump removal chemicals will vary from product to product, but all require drilling several holes in the stump. A measured amount of chemical is poured in each hole, and then water is added to fill the holes. Let the mixture stand for four to six weeks. Repeat applications may be necessary.

Sometimes the decaying stump is included in the landscaping. I saw a stump used as a miniature fairy garden recently that was really cute. Try adding containers on top of the stump for a different look. I once put a wooden wheelbarrow filled with annual flowers on a stump and added more annual flowers around the stump. Use your imagination and you may find leaving the stump is a good option.

If the tree is not completely dead when it is cut down the stump may produce sucker growth. You have two options to solve this problem. The quickest solution is to immediately treat the cut surface with an herbicide. You can also cut off all new sucker growth before it reaches eight inches to gradually deplete the stored food, but this can take five to ten years to be completely effective.

Finally, remember that dead trees are an important part of our ecosystem. Many birds and small mammals nest in dead trees. Consider leaving the tree if it is located in an area where it won’t be an eyesore or cause safety issues over time.

Sticky Plants are Annoying

While hiking recently I got to thinking about the various plants that stick to our sock and pants. Certainly, they are frustrating; but, as a plant geek, I wanted to know more.

Sticky plants attaching to clothes, hair, fur, and feathers to disperse their seeds into new areas. They do this with hooks, spines, barbs, and burrs. Let’s look at a few common examples that we find here in central Illinois.

The biggest challenge on my property is Spanish Needles (Bidens bipinnata). This weedy plant grows one to three foot tall in dry, shady areas. Its leaves are finely textured, looking a bit like flat-leaved parsley. The non-showy, yellow flowers develop into 2-4 prong, barbed fruit. They get their name from the fruit’s needle-like prongs, each with its own backward pointing barb.

Virginia Stickseed

Virginia Stickseed (Hackelia virginiana), also called beggar’s lice, has very small prickly bur fruit that clings to clothing. It grows one to four foot tall in dry woods. The burs are less than ¼” in size. Burs are arranged along one side of stems (racemes) that are held 2-8” above the plant.

Probably the most commonly known hitchhikers are burdock and cocklebur. In fact, Velcro is said to have been designed after the burs of the burdock plant. After a hunting trip, the inventor looked closer at the tiny hooks on the bur and created the hook and loop fasteners design.

Cocklebur

Burdock (Arctium sp.) is a robust plant. It is also called wild rhubarb due to its large leaves that can reach 20” long. This is a biennial plant that grows rhubarb-like leaves the first year. In the second year, it sends up 2-5 foot stalk with large egg-shaped leaves and ½ to 1” bristly purple flowers. Each fruit is a prickly, clinging bur. Unlike rhubarb whose stems are edible, burdock has an edible taproot.

Cocklebur (Xanthium sp.) is related to burdock. This plant sprouts from seed each year, reaching 2-5 foot by summer’s end. Its triangular, lobed leaves are 2-6” long. Cocklebur has both male and female green colored flowers. Female flowers form ½-3/4” burs that are held in the axils of the leaves. The football-shaped burs cling with hook-tipped prickles.

Bedstraw

Bedstraw (Gallium sp.) is sometimes called velcro-plant or stickywilly. Bedstraw attached to us in two ways. Its leaves and stems have fine hook-like hairs that cling to clothing and fur. However, it is the extremely small seeds that really create havoc. At less than 1/25 of an inch, the seed burs are covered with small hooked bristles. Because each plant produces hundreds of seeds, they quickly cover large areas of clothing. Their small size and abundance make them difficult to remove.

There are many more, but you get the idea. I have not developed a magic way for removing these from my clothes or pet’s hair. Washing clothes does not remove most hitchhiker seeds. They usually need to be picked off individually, though some can be scraped off with a butter knife.

Enjoy a fall hike in the woods, but try to avoid those hitchhikers!

Trees in Winter

Each season brings a different look to the garden. I enjoy each one, but I must say that plants are uniquely beautiful in winter. Now is a great time to see a plant’s texture and form - each unique and mystical.

left to right: Silver maple, red maple/dogwood, & redbud 

Look for the differences between these trees this winter: oak, maple, and redbud. Oaks are the kings of the forest. They soar well above the maples and smaller redbuds. Oaks are majestic in size and texture.

The white and bur oak are most majestic. A white oak will grow well over 100 feet tall in the wild. It has a medium to coarse texture in winter, but the wide-spreading branches exhibit a strong, bold appearance. Bur oaks are a bit more coarse in texture and probably even more majestic with massive trunks and stout branches.

There are many different types of oaks though. A pin oak is much different from the white and bur. Although still medium to coarse textured in winter, a pin oak has a strongly pyramidal habit. It is a strong central leader and pendulous lower branches. My college classmates called this the 55-mile per hour tree because we could recognize it even at highway speeds.

Maples also come in many different shapes and sizes, from the dainty amur maple to the sturdy sugar maple to the weak silver maple. Sugar maples grow 60 to 75 feet tall with a rounded character. They are hard, sturdy trees. Their texture is medium in winter. Notice their beautiful bark, which with age becomes deeply furrowed, with long irregular thick plates or ridges.

Silver maples are very popular because they grow fast. Unfortunately this is not always a good trait, since fast growing trees are usually also weak-wooded, often breaking in wind and ice.

The silver maples grow a bit more oval than rounded and are a bit coarser in the winter, often looking disheveled.

Amur maples and redbuds are similar in that they are both small, understory trees. The amur maple is a small tree or sometimes a multi-stemmed shrub, but is usually round shaped. It has very slender, fine branches and thus a medium-fine texture.

Redbud is a small tree with medium winter texture. Although best known for its spring flowers, it also has interesting bark in winter. The older bark is black or brownish with orange inner bark peeking through.

Enjoy looking at trees this winter. Also notice how terrible the topped trees look! Please do not top trees. It results in very weak, ugly trees!

Food Garden Safety Begins with a Lead Test Soil

The garden season is in full force, and I’m excited to hear about all the food and community gardens happening in our area. As we begin growing food and other plants this summer, please consider some potential health hazards.

Forest Hill Community Garden in Peoria, IL

A growing concern in urban soils is lead contamination, though suburban and rural soils may also be contaminated. I recently partnered with the Peoria City/County Health Department to highlight the importance of avoiding lead contaminated soil during the gardening season.

Some garden soil contains high levels of lead that can pose a serious health risk. The risk can be from contaminated garden soil brought into the house on clothing, shoes, tools, or clinging to vegetable crops. Soil becomes mixed with house dust that is inhaled or ingested, resulting in lead poisoning. Roots crops (carrot, radish) are more likely to contain high lead levels than fruiting (tomato, pepper) and leafy (lettuce, spinach) vegetables. The harmful effects of lead poisoning can cause lifelong problems such as learning disabilities, behavioral problems, and lower IQ 

Gardeners can reduce the risk of lead poisoning by following safe gardening recommendations. A good start is with a soil test to determine if the soil is contaminated with harmful lead levels. Garden soils can be contaminated with lead found in old house paint, old lead plumbing pipes, or old leaded automobile fuel. The greatest lead concentration is in the top 1 to 2 inches of soil.

Soil samples should be taken from several areas to determine the location of the contamination. Sample children’s play areas and vegetable gardens separately. With a trowel or shape, take several soil samples from within the chosen area. Combine the samples together, break up clods and mix the f soil thoroughly.

Use about one pint of the soil mixture as a sample to send for testing. Discard the remainder. Send samples to a soil testing lab with a special request for lead testing. Be sure the lab you choose does lead testing.

Gardeners can reduce the risk of lead poisoning from lead contaminated soils by growing food crops in raised beds. Covering ground at the bottom of an eight-inch high raised bed with landscape fabric, then fill with a good potting mix. Avoid using chemical treated lumber.      

More information on how to grow food safely in the home vegetable garden is found on the University of Illinois Extension Lead in Soils Resources website. In addition to a Lead in Garden Soils factsheet, there is also information on soil testing, soil labs, general gardening, other soil contaminants, and more.

Test Yard and Garden Soil Before Adding Amendments

Fall is the time to take soil tests. If you have plants that are not growing the way they should, a soil test might be needed to see if soil amendments are needed.

Fertilize Lawn Based on Soil Test Results

Soil amendments should be based on a soil test to know the amounts needed. Be sure the sample is representative of the area to be treated. The teaspoon of soil finally used for analysis weighs a few grams in comparison to about 50,000 pounds of soil per 1000 square feet to a six-inch depth.

Before sampling the area, size it up for differences in soil characteristics, such as color, texture and drainage. If these features are uniform throughout the area to be treated, a single composite sample of the topsoil is adequate. If there is great variation in these features, take a composite sample from each predetermined area.

Soil samples may be taken at any time of the year when temperature (soil not frozen) and moisture conditions permit. Late summer and fall sampling is a good choice based on factors affecting nutrient availability and time available to the gardener.

Within the area selected for a sample, dig a hole to spade depth. With a shovel or trowel cut a thin slice down one side of the hole. Place this slice in a pail or pan. Do not include sod roots. Repeat this procedure in at least eight well-scattered spots within the chosen area. Place each slice in the pail with those previously taken. Break up clods and mix the slices of soil thoroughly with the hands and by revolving the pail while held at an angle of 45 degrees. Use about one pint of the soil as a sample. Discard the remainder.

The sample is then sent to a soil testing lab. University of Illinois Extension has a listing of labs online at https://web.extension.illinois.edu/soiltest/.

Soil testing and fertilizer application is only one step in effective soil management. For best growth of lawns, vegetables and ornamentals, you should also provide the proper soil structure and soil moisture. Take time this fall to focus on good soil health, because soil management is essential for good plant growth.

Recycled Leaves Make Inexpensive Mulch

Fall brings wiener roasts, festivals, and leaf removal. I suggest making good use of the fallen leaves in your yard.

Ginkgo in Fall

The tree leaves that accumulate in and around your landscape represent a valuable natural resource that can be used to provide a good source of organic matter and nutrients for use in your landscape. Leaves contain 50 to 80 percent of the nutrients a plant extracts from the soil and air during the season. Therefore, leaves should be managed and used rather than bagged or burned. According to Rhonda, there are four basic ways in which leaves can be managed and used in the landscape.

First, a light covering of leaves can be mowed. Simply leave the shredded leaves in place on the lawn. This technique is most effective when a mulching mower is used. In fact, during times of light leaf drop or if there are only a few small trees in your landscape, this technique is probably the most efficient and easiest way to manage leaf accumulation.

Second, mulching is a simple and effective way to recycle leaves and improve your landscape. Leaves can be used as a mulch in vegetable gardens, flower beds and around shrubs and trees. Leaves that have been mowed or run through some other type of shredder will decompose faster and are much more likely to remain in place than complete leaves. I use a chipper shredder vacuum to pick up my leaves, which I use instead of purchased mulch in my landscape beds.

Third, leaves may be collected and worked directly into garden and flowerbed soils. A 6 to 8 inch layer of leaves tilled into a heavy, clay soil will improve aeration and drainage. The same amount tilled into a light, sandy soil, will improve water and nutrient holding capacity. A recommended strategy for using leaves to improve soil in vegetable gardens and annual planting beds is to collect and work them into the soil during the fall. This allows sufficient time for the leaves to decompose prior to spring planting. Adding a little fertilizer to the soil after working in the leaves will hasten their decomposition.

Finally, try composting your leaves. Compost is a dark, crumbly and earth-smelling form of organic matter that has gone through a natural decomposition process. If you have a garden, lawn, trees, shrubs, or even planter boxes or houseplants, you have a use for compost.

Get extra value out of your leaves this fall. And for fun, don’t forget to jump in the pile once!

Native Pollinators Are Important for our Food Supply

When it comes to pollination, honeybees get a majority of the attention. However, many insects play a role in pollination. 

Black-Eyed Susan and Purple Coneflower

What is Pollination? Pollination occurs when pollen grains are moved between two flowers of the same species, or within a single flower. There are many ways that flowers are pollinated, including wind and animals.

According to the website pollinator.org about 75% of all flowering plants rely on animal pollinators and over 200,000 species of animals act as pollinators. Of those, about 1,000 are hummingbirds, bats, and small mammals. The rest are insects such as beetles, bees, ants, wasps, butterflies, and moths.

Pollination is critical for many of our food crops. Hundreds of food plants are pollinated by bats. Other pollinators of our most colorful healthy foods include native bees, other insects, birds, moths, and butterflies, and more. Honeybees are not native here but are important pollinators of many of our food crops.

Coreopsis (yellow) and Penstemon (white)

The Xerces society has great information about pollinators on their website at www.xerces.org, including how to attract them to your garden. The usual recommendation is to plant a diversity of native flowers.

Wild Geranium

The goal is to have something flowering all summer long. Examples in my yard include wild indigo and wild geranium that bloom in early spring, followed by penstemon and coreopsis in early summer. By mid-summer the black-eyed Susan’s and purple coneflowers are in full bloom. In the fall, asters and goldenrod make a show.

Typically, native plants require less care and can tolerate more of our weather extremes. However, I’ve found that some routine maintenance does help the garden perform better. This year I’ve tried very hard to deadhead individual flowers, which prolongs the blooming of many perennial plants. I’ve also cut some back when they are done flowering, which in many cases helps the plant foliage look more attractive for a longer period.

Try adding native pollinator plants to your gardens.

Moss…Friend or Foe

On a recent (June 2012) camping trip in Southern Illinois my husband Mark kept taking pictures of non-flowering plants. His pictures made the ferns, mosses, lichens, and club moss look like something right out of a fairytale. In fact, these non-flowering plants do have their very own kingdom in the plant world. Instead of reproducing by flowers and seeds, these plants use spores to multiply. We were all particularly amazed by the various mosses.  

While hiking I discovered a large patch of club moss. I had never seen it before. Club mosses are ancient, prehistoric plants that reproduce by means of spores, either clustered into small cones or in the axils of their scale like leaves. I suspect that the one I saw was a ground pine because it resembled miniature evergreens with flattened fan-shaped branches. For a plant-geek like me this was an amazing find!

Club Moss

There are more than 13,000 species of mosses, which are small, primitive, leafy, green plants that develop fine, tangled mats over a surface. Various species are often seen on old brick walls, stone paths or walls, roofs, and rocks. Moss is something that we seem to love or hate. Many people try to get rid of it in their lawns, while others try to grow it.

In the right place, I love the look of moss. It is natural and in the right combination with wildflowers and other native plants helps create a stunning landscape. Psychologically, moss has a soothing, relaxing effect on people. It is a natural component of woodlands and shade gardens.

Mosses grow where other plants won’t, preferring low soil fertility, poor soil drainage, compacted soils, excessive shade, poor air circulation, high humidity, or a combination of these conditions. Mosses are not always found in low pH soils, thus altering the soil pH may not eliminate mosses. In turf, mosses are not the cause of turf decline, but a symptom of environmental or management levels that are unsuitable for supporting quality turf.

For areas where you do not want the moss, it can be eliminated, at least temporarily, by hand raking when it first appears or by applying ferrous ammonium sulfate or ferric sulfate.  Remember, however, that moss will probably reappear unless the environment and/or turf management program is altered.

For areas where you do want moss, the basic requirements are shade; compact, bare, acid soil; and moisture. The best time for transplanting is in early spring. Once established, moss is a tough plant. It is hardy from zones 2 to 9 and able to survive severe drought.

Although we often try to control and manipulate Mother Nature, sometimes “she” really knows best. Although I do not believe in gardening exclusively with natives, I believe native habitats tell us an awful lot. Sometimes it is worth considering “giving in” to situations where a certain plant wants to grow. Moss is a good example. It is a good alternative to grass in shady areas and in the right location can be used very effectively.

Don't Raise Mosquitoes in Your Yard

While doing your spring cleanup activities, be sure to look for mosquito breeding sites in your yard. The first step to fighting mosquitoes MUST begin in YOUR backyard.

West Nile Virus is most frequently transmitted through the house mosquito. Since it can only fly about 1-½ miles, this mosquito usually breeds and lives in our own backyards. After getting an adequate blood meal, the adult female mosquito lays her eggs in any stagnant water source. The eggs and larvae must have water to live. Therefore, we must remove as many water sources as possible from our yards and communities.

The water source does not have to be large. In fact, the house mosquito prefers small, nasty water pools. It can breed in water sources as small as an 8-ounce glass.

Keep birdbaths clean

Here are common areas in our yards that often hold enough water to breed mosquitoes: dirty gutters, flat roofs, tin cans, buckets, brake drums, bottles, candy wrappers, and trash. Most people know to eliminate tires, which are the Crown Plaza of breeding sites. Also, remember to keep swimming pools clean and dump water in tarps and other covers. Keep birdbaths clean and fresh.

For the gardener, remember to dump any water standing in containers or drip trays. Garden ponds should contain fountains or other features to keep the water moving or include top-feeding fish that will eat any mosquito larvae that try to develop.  Examples of top-feeding fish include Gambusia, known as mosquito fish, most bait minnows, guppies, or even goldfish. Koi are not recommended since they are vegetarians.

It’s hard to predict insect populations year to year.  Spring populations are easy to get a handle on due to winter conditions, but spring conditions have an effect on summer populations, summer weather affects fall insects, and so forth.   You really can’t predict problems for more than one season in a row.

Eliminating breeding sites can reduce mosquito problems in your yard.  This is key to any type of mosquito control program.  Fortunately, an ongoing program of eliminating these sites in your yard is easy and not time-consuming.  However, it must be done regularly – at least once per week since it takes mosquito larvae 5-7 days to develop.

For areas where the water cannot be eliminated, there are other options for controlling the larvae.

Mosquito-eating Fish Another Weapon In Mosquito War

Last weekend (May 2003) we bought fish to add to our new pond. For now, we have mostly goldfish, except for one mosquito fish. We might add a koi later.

My new pond is quite large and when done will have a complete aquatic ecosystem of plants, water, and fish. It also has a small waterfall in one corner. The movement from the waterfall should be enough to keep mama mosquito from laying her eggs there, but if she does the fish will eat them!

 

Fish are excellent weapons in the fight against mosquitoes. The artillery includes minnows, goldfish and Gambusia affinis, also known as "mosquito fish.”  One small mosquito fish can eat up to 100 mosquito larvae each day.  They can make a big difference in a home’s water garden or small pond.

 

Mosquitoes go through their larval stage in water, whether it is a lake, river, water garden, gutter or birdbath.  Any container that holds water, and especially water that stagnates, is a prime breeding ground for mosquitoes.

 

Gambusia are related to and look very much like guppies. The males are cigar-shaped and are about an inch long. Female Gambusia are slightly larger and typically have a potbelly where they carry their developing young.  Gambusia are aggressive, eating young game and other fish.  They should not be released where they can escape into natural bodies of water. Introducing these fish to a new area carries some risk of introducing new diseases to existing fish.

 

Gambusia aren’t the only fish that eat mosquitoes.  Other surface feeding fish such as goldfish and minnows work well in controlling mosquito larva.  Koi, which tend to be bottom feeders, are not effective in controlling mosquito larva.

 

But none of these fish are effective at eliminating mosquito larvae when dense vegetation is present.  Dense vegetation can provide cover for mosquito larvae and make it difficult for fish to locate and consume them.  Reducing excess vegetation in and around the water garden is recommended.

 

Increasing water movement in ponds and water gardens, and eliminating standing water in old tires, gutters, and other water-holding containers are two strong tools in eliminating mosquito-breeding sites.

Lightning Bugs on the Decline

I hear a news report about the decline of the monarch butterfly almost every day, but there are other insects in decline as well. One that is a favorite of all ages is the lightning bug, which some folks also call a firefly.

As a kid I remember catching lightning bugs on warm, summer nights. We put them in empty canning jars or pickle jars, poked holes in the lids, and watched the bugs glow in our new natural lantern. Although I hate to admit it, I also sometimes ripped off the abdomen of the bug to make a glowing ring on my finger.

Lightning bugs flash light to attract the opposite sex using a chemical called luciferase. There are over 136 species of lightning bugs, each with a distinctive rate of flashes per second. Male lightning bugs flash patterns of light to females who then signal in response from perches in or near the ground. When the male sees the female's flash he continues to signal and moves closer until they finally find each other and mate.

Lightning bugs are actually a type of beetle that is very beneficial in our ecosystem. The larvae stage of this beetle is a specialized predator that feeds on other insect larvae, earthworms, snails, and slugs. The tiny larval stage is dark gray with three pairs of legs and tiny spots on their underside that sometimes softly glow.  Some adult lightning bug species are also predators, and other species don’t eat at all in the adult stage. 

Large swarms of lightning bugs are a less frequent occurrence in many areas. I can remember a midnight float down the Illinois River a few years ago when the river bank was alive with millions of flashing fireflies. This summer I saw lightning bugs, but not in large numbers. They are most prevalent away from city lights and in more open areas of vegetation.

According to www.firefly.org firefly populations are dwindling all over the country, and the world. Researchers are not sure exactly what is causing the firefly decline, although most researchers think that habitat loss and light pollution from urban development are to blame.

Most fireflies need undisturbed natural areas to survive. They overwinter as larvae buried in the soil and hide during the day under bark or stones or in decaying vegetation.  Mud is needed for the pupal stage. Human light pollution is believed to interrupt firefly flash patterns and thus their mating rituals.

If you want to help researchers learn more about this insect, consider participating in a fun citizen scientist project called Firefly Watch. You simply watch fireflies in your own backyard or favorite outdoor location and record those observations online at https://legacy.mos.org/fireflywatch.

The next time you see one of these magical insects, think about how they are more than just funny flashers. They benefit our ecosystem and are also beneficial to humans. Their luciferase has been genetically engineered as an enzyme that helps screen for human tumors, test for blood problems, and detect infections faster. Wow!
