Crab Apple Defoliation from Mold: Fungicide Spray — Prevents Repeat

Albany, NY: 17-yr crab apple defoliated last year after cool damp spring — mold on trunk again this spring.

Solution

Fungicide spray (per label) — controls mold/mildew.
Natural cycle — won't kill tree unless repeated annually.
Mulch change (stone → cedar) irrelevant.
