Globe Willow Leaf Drop in Drought: Watering Deficit

Globe willow dropping leaves in late July during drought. Owner used occasional drip irrigation; nursery said "water the heck out of it."

Problem

Willows need MORE water than most trees. Lawn sprinklers and drip lines are insufficient.

Solution

Water deeply: 1 inch every 3 days for a month (pan method), then weekly. Stop when weather cools/rains return. Heat + chronic underwatering = leaf drop with brown edges/spots.
