Fishtail Palm
Caryota mitis
Through the year 🗓️
☀️ Summer now
Water and mist generously. This is its sprint season and it will drink more than you expect.
🍂 Fall
Slow the watering rhythm and stop feeding as light drops.
❄️ Winter
Keep soil lightly moist, boost humidity near heaters, and check weekly for spider mites.
🌱 Spring
Pot up root-bound clumps and resume monthly feeding as growth takes off.
The details
Light & placement
- Light
- Bright indirect with a little soft morning sun; fronds bleach in harsh midday sun
- Ideal PPFD
- 200–400 µmol·m⁻²·s⁻¹
- Grow-light distance
- 14–20 in below LED
Water & feed
- Watering method
- Keep-evenly-moist: water when the top inch dries. It drinks fast in good light and wilts dramatically if forgotten.
- Fertilizer
- Balanced feed at ½ strength, monthly in spring–summer.
Home & habit
- Soil
- Rich, moisture-retentive but draining mix (peat/coco + perlite); pH 6.0–6.5
- Humidity
- High (50–60%+); tips crisp quickly in dry air
- Temperature
- 65–85 °F
- Mature size
- 6–10 ft indoors
- Repotting
- Every 2 yrs in spring; it grows faster than most palms and roots fill pots quickly
- Propagation
- Division of basal suckers (it clumps) or seed; single stems die after flowering, so keep the clump.
When something looks wrong
- Overwatering signs
- Yellowing fronds, sour soil, blackening stem bases
- Underwatering signs
- Dramatic all-over wilt, crispy brown leaflet edges
- Common pests
- Spider mites (its chief tormentor), scale, mealybugs

Filtered water, humidity above 50%, and a flush of the pot every few months.
Sticky residue or webbing
Likely cause
Scale or spider mites.
What to do
Wipe the fronds down and treat with horticultural oil or neem weekly until clear.
Whole fronds yellowing
Likely cause
Overwatering, or a hungry plant late in the season.
