These articles are written to apply to the northeastern corner of Illinois. Problems and timing may not apply outside of this area. While fall is typically thought of as a time for clean up in the yard, it is also an important time for many plants to grow roots.
Cultural practices can help encourage rooting of plants such as trees and turf.
Even though most of the area received significant rain at the end of September, water is critical for rooting and winter preparation for lawns, trees, shrubs, and other perennial plantings. If conditions turn dry, water landscape plantings to assure they go into winter in good shape. Fall fertilization can also help root systems of lawns, trees, and shrubs. For lawns, early and late fall are suggested times for fertilizing. Right now we are somewhat in between, as the next suggested time would be about Halloween or slightly later.
