Fishtail Palm problems & how to fix them
Caryota mitis
Drooping, yellowing, brown tips, or a plant that just won’t thrive? Here are the most common Fishtail Palm problems, what usually causes them, and how to turn things around.
Common problems
Spider mites
Its most notorious indoor problem — dry air turns the fishtail leaflets grey and stippled fast. Tiny sap-sucking mites that thrive in warm, dry air and leave fine webbing and speckled leaves. Caught early they are very treatable; most plants recover fully within 3-4 weeks of consistent treatment.

Crispy tips (low humidity)
Low humidity chronically browns the ragged leaflet edges. Brown, dry leaf tips caused by air that is too dry for the plant, common in heated or air-conditioned rooms. Existing crispy tips never turn green again, but with higher humidity new growth should come in clean within a few weeks.
Underwatering
A missed watering in summer browns whole fronds on this fast grower. The plant is not getting enough water, either from infrequent watering or soil so dry it repels water. Prognosis is excellent - most underwatered plants perk up within days of proper rehydration.
Nutrient-deficiency yellowing
Fast growth in old soil runs short of magnesium and iron, yellowing older fronds. Leaves yellow because the plant has run out of one or more nutrients, usually after a long time in the same soil with no feeding. Old yellow leaves rarely green up fully, but with steady feeding new growth returns to a healthy color within 3-6 weeks.

The mistakes that most often kill it
- Dry air plus spider mites — the standard death spiral for indoor fishtails.
- Letting the root ball dry out during active growth.
- Cool drafts and cold windowsills in winter.
