Container gardening offers a practical and beautiful solution for growing flowers, vegetables and herbs in central Illinois where weather extremes and limited space often challenge traditional gardening.
For leafy edibles, start with herbs and salad greens, which tolerate a wide range of light conditions from windowsill to kitchen garden and actually favor a little shade relief from the Illinois summer heat. For brilliant statement arrangements, experts like the three-species approach of “thriller, filler, spiller,” or, as one social media influencer says, “tall, thick and trailing.” For vining and root vegetables, plant as early as possible in large, deep containers. The Illinois growing season can be fickle – and short.
Whether on a patio in July or under grow lights in January, here’s how to make it work.
Don’t lose it, move it
One of the greatest advantages of container gardening is mobility. Plants can be moved to follow sunlight, avoid storms and escape early frosts. In fact, one of the most encouraging hallmarks of glad gardening is knowing that nothing has to be permanent. If your first try isn’t thriving, it’s easy to make adjustments. In addition, although the start-up cost of purchasing the growing medium can be expensive, the ability to overwinter container perennials indoors offers a significant and satisfying savings.
Local gardener Veronica Fesser gardens all winter in a compact, sunny greenhouse full of colorful showstoppers, succulents, trees and ferns. It’s also where she starts some of her seedlings for the next growing season. On an unseasonably warm day in a cold weather month, Fesser can move some of her plants out for a breath of fresh air.
“This is one of the reasons I love gardening,” she says. “I can do it year-round.”
Designing for small spaces
Space efficiency is where container gardening truly shines. Vertical gardening with fences, trellises, railings or stacked systems allow vining cucumbers, beans and even some squash varieties to grow upward instead of outward. This saves space and improves airflow and sunlight exposure.
However, vertical multi-compartment towers come with trade-offs. They maximize production per square foot but complicate watering and soil consistency. Fesser’s vertical tower planted with herbs and small flowering plants made efficient watering impossible.
Water falls through rather than spreading out, she explains. And, even outdoors, rain showers typically only watered one side at a time. Instead, select single planters and water selectively.
Large stand-up gardens 2 to 3 feet off the ground may offer the best option for those with physical limitations, munching rabbits and a love of trying new things on a small scale. In large wooden bins, use a potting soil mix, occasionally provide a tent cover to protect from harsh weather and enjoy a longer growing season, and properly space plants to ensure good sun and air flow.
Also, whether buying ready-made or constructing your own, consider the building material. Untreated lumber used for tomatoes, herbs and other edibles will likely rot sooner than treated lumber that you may not want for your edibles. An inside lining barrier for the treated lumber could be one way to solve the problem.
A good start
Apart from an animal eating your newly planted bulbs or a surprise hail storm, few decisions in gardening are ever final. But a proper growing medium, placement and container will help from the start.
Garden soil, even commercially bagged, should not be used in containers. It compacts easily and restricts oxygen to the roots. Fesser uses two parts peat moss, one part perlite and one part vermiculite to start her plants. Consider wearing a mask to prevent dust exposure while handling the growing medium before it is damp. She also uses two high-quality potting mixes that contains “a lot of nutrients and natural fertilizers.” One of her favorites includes earthworm castings and bat guano.
Thoroughly water the medium before planting, she says, and then “finger test” once or twice daily to optimize plant growth. That is, push your finger into the soil up to the first joint. If damp, don’t water. Overwatering is one of the container gardening pitfalls. But, if the soil is dry an inch or so down, water slowly not only to avoid too much water for that species, but because very dry soil can actually repel water, causing it to run out of the bottom without benefiting the plant.
A fun aspect of container gardening is choosing the container. Just about anything can work, although size and weather-worthiness do matter. For example, clay pots are breathable but dry out more quickly, and glazed clay pots will often crack if left outside in the winter. Plastic pots in full summer sun can overheat tender root systems. Small herbs can thrive in small pots, but larger plants need deeper, larger pots. And they all need good drainage to avoid root rot. The University of Illinois Extension offers excellent information on its website to address these questions.
Indoor gardening
With sufficiently bright lighting, often from full-spectrum LED lights, warmth, proper water, and, for seed starting, a gentle fan breeze, plants can start and stay indoors, or start outdoors and come inside for the winter. This is especially fun when starting seeds for next year’s vegetables, for growing herbs year-round or for keeping flowering plants blooming. One successful Mechanicsburg farmer-gardener moved a long-lived, large hibiscus with brilliant red blossoms from the outdoor patio into his Victorian-styled living room every year for a spectacular Christmastime showpiece.
Always check for bugs before bringing container plants indoors, and spray undersides of leaves with insecticidal soap if necessary, Fesser advises.
The joys of container gardening
Need an accent by the door or in the yard? Maybe you have just enough room on your balcony to grow culinary herbs. Or perhaps poor soil, limited budget, no time or senior knees make a fully landscaped yard impractical. Use containers for versatility, drama, scale and ease.
Social media reels will provide all the incentive, ideas and encouragement you need. And container gardening truly provides instant gratification.
