New Arborvitae Dying: Pot-Bound Roots or Transplant Shock

Investigating Summer-Planted Arborvitae Failure

A gardener planted 10 seven-foot arborvitae from Home Depot in summer; they're turning dry yellow/brown despite moist soil and no fertilizer.

Check for Pot-Bound Roots

Ed Gulliksen asks: were roots still in container shape when dug up? "Pot-bound" roots circle instead of expanding—score root ball sides before planting to prevent this.

If Not Pot-Bound: Transplant Shock

• Low-nitrogen granular fertilizer – Stimulates recovery
• Maintain good watering – Consistent moisture
• Proper mulching – Root protection

Most recover with supportive care.
