Troubleshooting
Cabbage Palm problems — and how to fix them
Cabbage Palm (Sabal palmetto) 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.
Frizzle top / manganese deficiency
New fronds emerge weak, frizzled and withered when manganese is lacking. Apply a palm fertiliser with manganese, especially on alkaline or sandy soils.
Potassium deficiency
Older fronds show yellow-orange spotting and necrotic, frizzled tips. Feed a slow-release palm fertiliser supplying potassium and magnesium through the season.
Transplant shock and slow establishment
Field-dug palms are slow to root and may decline if over-pruned at planting. Keep most fronds, water consistently until established, and avoid hurricane-cutting the crown.
Ganoderma butt rot
A soil fungus causes incurable trunk-base decay with conks at the base. There is no cure; remove affected palms and avoid replanting palms in the same spot.
Prevent cabbage palm problems before they start
Most cabbage palm issues are care-mismatch, not bad luck. Dial in the basics:
