As drought conditions persist in the Chicagoland area, residents are reminded to please water trees and woody vegetation. Leaves that are wilted, drooping, browning or falling off early are signs of serious drought stress.
Trees and woody vegetation can survive drought if water is applied slowly around the stem so the water percolates down into the soil. Thoroughly moistening the soil twice a week is more efficient than several light waterings. For larger trees, letting a hose trickle around the base of the tree until the ground is moist is also effective.
A layer of mulch, such as wood chips, around trees and vegetation will help conserve soil moisture.
