Welcome to astronomical winter! Our calendars mark the beginning of winter as December 21 (sometimes the 22) because of where Earth is in its orbit around the sun. Is it too much of a leap to say that gardeners and those who work outdoors are particularly connected to this astronomical event?I have...

During the holiday season, plants often play a central role in our decorations. While poinsettias, ...

Three of my most prized trees are the oaks we planted in our front yard shortly after we moved. They share our front yard with a black gum (Nyssa sylvatica), red twig dogwoods (Cornus sericea), witch hazel (Hamamelis vernalis) and apple (Malus spp.) trees. ...

As Thanksgiving approaches, many of us start planning our holiday meals. While turkey,...

As the autumn leaves fall from our trees, the trunk and branching structure become more prominent and visible. This transformation can add new dimensions and interest to a landscape, but it can also draw our attention to tree health challenges we might have overlooked in other seasons. As we...

If there is one certainty for all humans is that we are drawn to natural elements. Two of the best examples are how we can become transfixed when looking at fire or water. Scientists have studied this effect and shown that our brains reduce stress chemicals when we are staring at a fire, water, or...

As the days get shorter and the temperatures get cooler, many species of insects will search for places to spend the winter. Depending on the insect, they may seek out a variety of locations, such as in soil, under leaf litter, under tree bark, or even in our homes. One that we commonly...

The natural process of trees shedding leaves in the fall is the most visible sign of trees preparing for winter dormancy. Shedding leaves is a tree’s way of self-preservation, reducing plant material that require resources that become scarce during the cold days and short daylight of winter.While...

Autumn is a time for…life? This may seem perplexing, as we often link fall with plants dying, wildlife migrating, and us retreating indoors. However, this is when conservationists managing prairies get excited to sow new life.Managing prairies, forests, or wetlands often involves battling nonnative...

Annual geraniums (Pelargonium) are among the most popular flowering plants grown in gardens. These easy-to-grow, low-maintenance plants provide color to landscapes from May until the arrival of frost. After the first hard frost, they are typically destined for the compost pile, but that...

During this first week of October, many of the plants blooming in our landscape are mums, asters, goldenrods, sedums, and ornamental grasses. But what if your lilac is blooming? A lilac blooming in autumn is unusual unless you have planted one of the new varieties bred to bloom once in the spring...

Habitat was once thought of as something outside of town in the countryside. Today incorporating habitat into home landscaping in and around towns and cities has become a top trend across the United States. However, a naturalistic landscape design style does not always fit our HOA...

The recent turn in the weather has me feeling all the fall vibes. I’m ready for leaves to turn, for pumpkin spice to be in everything, and for sweater weather. Although as a kid and young adult, Halloween hasn’t traditionally been my favorite holiday, my kids love it which means I love it. As our...

Despite the bad name they get, yellowjackets (Vespula spp.) are beneficial insects. The larvae are meat eaters, consuming caterpillars and other insects (and occasionally carrion) that adults have captured and brought back to the nest. Adults, on the other hand, primarily feed on flower...

For the most part, we think of fungal infections as undesirable and cause adverse effects on plants. Fungal pathogens can destroy crops, weaken and deform plant parts, or kill the host plant entirely. Fungal pathogens cause billions of dollars of economic loss annually. Within this context, as we...

You sprayed what? Where? There are a few occasions when it is a good thing people can’t read my facial expressions over the phone. One of those situations is when I get a phone call where someone has used a pesticide that is way off-label. By off-label, I am referring to spraying a pesticide...

If you’ve driven along any interstates or highways in Illinois, there’s a good chance you’ve seen tall plants with spiky flower heads. Teasels have become an increasingly common sight across Illinois. While they may appear attractive, especially for cut flower arrangements, these troublesome plants...

Finding interesting insects is fun! At least for me. I enjoy observing the intricacies of most insects. However, there are a few creepy crawlies I do not want to see, especially in my house. What insect has been on my “Most Un-Wanted” list? Termites. When we bought our house a few years ago we...

Magnolias are popular trees and shrubs in many landscapes. Their large, showy flowers can range from white to pink to yellow and provide a burst of color in the spring. While they are relatively pest-free, one of the biggest pests is the magnolia scale (Neolecanium cornuparvum), which...
