Sugar Maple Root Damage from Edging: Recovery Through Fertilization

Sugar maple (planted 2007, now 11-12 ft) had landscaping/edging 4 inches deep in June. Noticed roots, now new leaves stay small, some established leaves turning brown.

Diagnosis: Root Pruning Shock

Edging likely severed surface roots (maples have shallow roots). Root loss reduces foliage support → smaller leaves, dieback. Tree will recover if no further root disturbance.

Recovery Plan

Next spring: Fertilize with 10-10-10 at 1 lb per inch trunk diameter, scattered and watered in (or before rain). This boosts overall health and recovery.
