Now that we finally have some heat in Chicagoland, don't forget to water. Containers especially need it often since they dry out fast. Water and let it drain through the pot. Then water another time or two.
Also, keep newly planted trees and shrubs well watered until established. A good schedule is every day for the first week, every other day for the second week, etc., for at least three weeks. Let the hose run at a trickle for 30 to 40 minutes.
A long soak every few days is better for all in ground plants and lawns than every day for a few minutes. It encourages the roots to go down for water and nutrients and not stay at the surface. And water plants at the base - not on the leaves. Some plants can get powdery mildew and other problems from wet foliage.
