Black Knot and Leaf Issues on Young Higan Cherry

Black Knot Requires Immediate Pruning

Black tar-like galls on Higan cherry = black knot. Prune 2–3" below galls in dormancy. On large limbs, chisel out +1" healthy bark. Burn prunings. Fungicides (captan) from bloom to shuck split help but don't replace sanitation. Leaf holes/yellowing: unidentified; monitor.
