Coral Bark Japanese Maple Decline After Repotting: Root Stress

The Timeline

30 days ago repotted, found worms, replaced soil. 2 weeks ago tips blackened, leaves fell. Was healthy before.

Analysis

Worms incidental. Black tips + leaf drop = root stress (water extremes, nutrition, pot‑bound).

Care

Snip dead tips.
Ensure pot drains well, room for roots.
Stress likely temporary; monitor.
