Linden Tree Leaf Gall: Mite Management Timing

25-Ft Linden in Minnesota, Poor for 3 Years

Full sun, sprinklers 25 min every other day. Leaf gall suspected. How to get rid of it?

Gall Control Reality

Leaf galls don't harm tree long-term. Control rarely needed. Learn life cycle—no lasting damage.

Options (If Insisted)

• Dormant Oil: Trunk drench for overwintering mites (discouraged on maples).
• Sprays: Must apply exactly when new leaf buds open—window very short. Once gall formed, too late.
• Systemics: Limited evidence of success. Too late after gall forms.

Recommendation

Hire certified arborist for evaluation.
