Japanese Maple Split Trunk: Bolt & Graft Repair

Snow‑Split Trunk Can Be Saved

After snow melts, pull halves together and:

1. Wrap tightly with small rope.
2. Coat with grafting wax (nursery source).
3. Drill through trunk; insert ¼″ threaded bolt with large washers; tighten.
4. Add second bolt 3″ lower.
5. Remove rope after 1 growing season (before it girdles).
6. Bolts stay; tree grows over them.

Works best on young, vigorous trees. Success = callus fusion across split.
