Maple Decline Misdiagnosed as Gall Disease: Root Binding Real Issue

4-year-old maples in SE Michigan show gall disease; some dying with half canopy bare. Company claims galls kill trees, wants $45/month oil spray.

Real Problem

Galls don't kill trees. Root binding likely—augered holes in clay create "in-ground pots" with circling roots choking each other. Roots can't expand, can't support foliage. Galls attacked weakened trees secondarily.

Action

Don't pay for gall treatment. Check root system by digging. Company diagnosis incorrect. Address root binding if confirmed.
