How to care for Fishtail Palm

Caryota mitis · Arecaceae

palmdemanding to growtoxic to pets

A clustering palm instantly recognizable by leaflets shaped like ragged fish tails — the only palms with such doubly-divided (bipinnate) fronds. It grows fast and lush with generous light, warmth, and humidity, but sulks and browns in dry rooms. A striking choice for bright, spacious interiors. Water roughly every 5 days while it's growing (about every 9 in winter), give it bright, indirect light, kept above 55°F (13°C) — it wants humid air.

Care at a glance

Water: every ~5d growing · ~9d dormant
Light: Bright, indirect light
Humidity: high humidity
Keep above: 55°F (13°C)
Feed: every ~30d in season
Repot: every ~2 years

Keep the soil consistently lightly moist — it is thirsty in growth and quick to brown if the root ball dries.

Very bright, filtered light near a large window; some soft morning sun is welcome, harsh midday sun is not.

Half-strength balanced feed monthly — it is a relatively hungry, fast-growing palm.

Mistakes that kill this plant

  • 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.

Seasonal tips

  • Humidity is the make-or-break factor — humidifier or grouped plants in winter.
  • Shower the foliage monthly to keep spider mites suppressed.
  • Each cane flowers once at maturity and then dies — cut spent canes out and let the cluster continue.
