Cuban Petticoat Palm problems — and how to fix them
Cuban Petticoat Palm (Copernicia macroglossa) 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 frequent cultivation problem; always allow extended drying between waterings and ensure excellent pot drainage.
Potassium deficiency
Manifests as yellowing and necrosis on older fronds; use a palm-specific fertiliser with potassium and magnesium.
Cold sensitivity
Not frost-hardy; move containers under cover when temperatures fall below 10°C.
Spider mites
Can affect foliage in dry, warm conditions; treat with insecticidal soap and improve ventilation.
Frond skirt fire hazard
The dead-frond skirt is highly flammable; in fire-prone areas, remove the skirt by stripping old fronds away from the trunk.
