Herbicide Drift Suspected in Fruitless Mulberry Yellowing

One fork of a fruitless mulberry shows rapid leaf yellowing and drop after cool, damp spring turned to 95-105°F. Yard was sprayed with crabgrass killer.

Diagnosis

Herbicide drift from crabgrass killer application (especially on windy days) can cause localized tree damage. The sudden heat transition adds stress.

Action

Wait and monitor. Examine the affected fork's base for bark damage. Avoid further herbicide use near the tree. Most trees recover from sub-lethal herbicide exposure if not repeated.
