Pruning a Large Multi-Trunk Mulberry Tree: Haircut, Not Topping

Don't Top or Heavily Prune

• Bleeds excessively.
• Cuts >2″ don't heal.
• Dormant pruning reduces bleeding.

Five Rules for Proper Pruning

1. ≤⅓ canopy/year. More? Wait for next year.
2. Cut to parent limb or side branch (≥⅓ diameter of removed part). No stubs.
3. ⅔ foliage in lower crown. Mushroom shape, not umbrella.
4. 80–90% wood removed in ≤5 cuts. Plan before cutting.
5. No topping (except utility safety).

Recommendation

Hire certified arborist (ask Extension Service). Not a DIY job for this size/complexity.

Key Takeaway

Large mulberries need artistic, minimal pruning by a pro. Topping and stub cuts ruin structure and health.
