Winter is an excellent time for reflection on the past year’s growing season and any gardening successes or failures to account for next year. In this season of multitudes of seed catalog mailings, I have found it to be an ideal time to set gardening goals for the coming year during the down...
Before we know it, spring will be here. Before getting too busy planting the garden, make sure to take some time to prune your trees (if they need it). While the old adage may say, "prune when your pruners are sharp", most deciduous trees are best pruned while they are in full dormancy. In this...
Historically, our part of Illinois has been more prone to ice storms than the northern or southern part of the state. Based on over 50 years of weather data from the Illinois State Water Survey, our area of Illinois (including Springfield, Bloomington and Champaign) is likely to have an...
The emerald ash borer (Agrilus planipennis) is an insect from Asia that has plagued our native ash trees in Illinois since 2006. This pest was first introduced in 2002 around the Detroit area and has rapidly spread across Michigan and Indiana to infect most of Illinois today. ...

Illinois forests are dominated by a mixture of eastern deciduous forest trees and many of our urban areas mirror this forest composition creating a wonderful palette of fall colors each year as the growing season concludes and tree leaves senesce, giving way to winter dormancy. As a tree-...
Last weekend’s fall weather has certainly set leaf drop into motion for the year. I noticed some of the early droppers stating to thin their canopy as many of the walnut around our property are already yellowing and loosing leaves. Cottonwoods are half bare, dropping more leaves each...
Anyone with a mature black walnut (Juglans nigra) on their property is likely aware that fruits are ripe now, and the baseball-sized, green bombs are beginning to fall with each slight gust of wind or, at times, seemingly at random. This native tree is prevalent throughout central...
Some plants don't seem to play well with others. In particular, a few plants release chemicals to try to keep other plants from growing too near. This botanical war tactic is known as allelopathy. Black walnuts (Juglans nigra) are one of the best-known allelopathic plants. Black...
