Troubleshooting
Rock Palm problems — and how to fix them
Rock Palm (Brahea dulcis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot
Overwatering in poorly draining soil is the primary risk; always ensure containers have drainage holes and soil is partially dry before rewatering.
Potassium deficiency
Yellow-orange mottling on older leaves is characteristic; apply a palm fertiliser with elevated potassium and micronutrients.
Spider mites in dry conditions
Increase ambient humidity slightly and rinse foliage; apply insecticidal soap for persistent infestations.
Slow growth
This species grows slowly; patience is required — fertilising lightly during the active season is the best encouragement.
Leaf tip browning
Often caused by low humidity or salt build-up in the soil; flush the pot thoroughly with water every few months.
