Thatch Palm problems — and how to fix them
Thatch Palm (Thrinax radiata) 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 from overwatering
The most common killer. Use gritty mix, water sparingly and never let it sit in water.
Frizzled new fronds
Manganese deficiency, common in alkaline soil. Apply a palm feed with manganese.
Slow growth misread as decline
Naturally very slow; patience is essential. Don't overcompensate with feed or water.
Cold injury
Tender below about 4-5°C. Frost browns fronds and can kill it; keep warm and frost-free.
