Pruning Storm‑Damaged Arborvitae: Save or Remove the Broken Limb?

The Damage

Heavy snow snapped two large limbs on a 20‑foot arborvitae. One limb has a two‑foot lengthwise split high in the canopy, but growth above the split remains green.

Decision Guide

• Wait and watch: If the limb is still alive, it may compartmentalize the wound and survive, though the shape may be permanently altered.
• Prune now: If the broken limb is unsightly, poses a hazard, or shows signs of dieback (browning needles, brittle wood), remove it cleanly at the branch collar.

Key Points

Without seeing the tree, a definitive answer isn’t possible. Either approach is acceptable—arborvitae often tolerate losing a limb. Ensure the tree is well‑watered and fertilized to support recovery.
