Troubleshooting
Carnarvon Fan Palm problems — and how to fix them
Carnarvon Fan Palm (Livistona nitida) 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.
Spear pull in cold snaps
The growing spear can rot and pull out easily after temperatures below -5°C, particularly if the crown remains wet. Protect with horticultural fleece and keep the crown dry during cold spells.
Potassium deficiency
Manifests as translucent yellow-orange spotting on older fronds followed by necrosis. Apply a palm-specific fertiliser with elevated potassium and magnesium; avoid fertilisers with excess phosphorus.
Root rot in heavy soil
Waterlogged conditions cause Phytophthora root rot, leading to yellowing fronds and crown collapse. Improve drainage before planting; raise planting level slightly in clay soils.
