Dog-Damaged Dendrobium: Encouraging New Root Growth

Dendrobium Root Ball Destroyed by Dog: Recovery Steps

Debbie's dog destroyed the root ball and part of her Den. inagaki Pink orchid. Asks how to encourage new root growth.

Expert Response

Debbie, most Dendrobiums have a rest period before new growth. If plant wasn't producing new growth before accident, ensure it's tightly potted and water very sparingly. If new growth was emerging, keep tightly potted but resume regular watering/feeding. Seal any exposed new tissue with antifungal powder (powdered sulfur, Rootone) against fungal growth. New roots will occur naturally when plant resumes growth cycle. Rootone can stimulate root growth only during growth cycle. Old canes support new growth—preserve them. During rest, mist canes occasionally to prevent shrinkage.
