Even trees are affected by the drought and hot weather. They aren’t about to keel over, but they will wilt, says Chuck Scott, director of the Fell Arboretum at Illinois State University in Normal. He says the hot wind draws moisture up from the roots, through the trunk and branches and out through the leaves.

“Trees are hurting from this heat and this wind. The wilting of the leaves is what is the manifestation of that drought. In some cases, trees will drop their leaves, but it most cases it’s primarily just a wilting,” he said. Long-term consequences are a stunting of the growth of trees, which property owners may not notice for several years. Scott’s recommendation: Water, slowly and deeply, around the base of the tree.
