Troubleshooting
Sugar Palm problems — and how to fix them
Sugar Palm (Arenga pinnata) 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.
Low humidity stress
Frond tips brown rapidly in dry conditions; maintain humidity above 60% and mist frequently.
Root rot in cold, wet conditions
Watering with cold water or in cool temperatures promotes root disease; use tepid water and maintain warmth.
Potassium deficiency
Older fronds develop yellowish to orange necrotic markings; supplement with palm fertiliser.
Spider mites
Common in dry indoor environments; treat with insecticidal soap and improve humidity.
Hapaxanthic lifecycle
This species dies after flowering and fruiting; there is no remedy — plan for succession planting in the landscape.
