When water restrictions are lifted in the fall, encourage property owners to provide regular watering to their trees and shrubs—as long as temperatures remain above about 40° F.
Water in the morning. Doing so gives the water as much time as possible to soak into the ground before possible freezing overnight temperatures.
Apply a deep watering with a soaker hose to the root zone under the branches of the tree. The idea is to get water down into the 12-inch depth of soil where all the tree roots are.
The general rule of watering is to apply about 5 gallons of water to the tree, then an additional 5 gallons for every inch of trunk diameter. For example, a 4 inch-diameter tree will get 25 gallons of water. Water deeply like this once per week, or when the soil has drained and feels less moist.
