Kentia palm (Howea forsteriana) care

Palms · easy to keep

Kentia palm (Howea forsteriana) wants medium indirect light, and tolerant of shade. Water it every 8 days. Keep the top of the compost just barely damp. Palms will not forgive a pot left standing in water, and brown tips are the receipt for the one time you let it dry out hard. Pot it in standard compost with perlite. A weak balanced feed monthly in spring and summer only, and repot every 2 years. Humidity: above 50% keeps the tips green. Non-toxic to cats and dogs.

The kentia palm: dark arching fronds on slim canes, tolerant of shade, cool rooms and general neglect. It is the most forgiving palm sold and the most expensive, because it grows slowly from seed on a single island — Lord Howe, off Australia — and cannot be rushed.

Watering a Kentia palm

Water every 8 days. Keep the top of the compost just barely damp. Palms will not forgive a pot left standing in water, and brown tips are the receipt for the one time you let it dry out hard.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Medium indirect light. Kentias are the most shade-tolerant palm sold as a houseplant, and the most forgiving overall — which is why they cost more.

Humidity and temperature

Above 50% keeps the tips green. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

Ordinary peat-free compost with perlite through it. Palms want moisture-retentive but never waterlogged.

Feeding

A weak balanced feed monthly in spring and summer only. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot every 2 years. Every two or three years, and reluctantly — palm roots resent disturbance. What is sold as one plant is usually a dozen seedlings in a pot; keep them together.

Common problems

Brown tips on every frond
Dry air, hard tap water, or a dry spell. Almost universal indoors.

Fix: Raise humidity, water with rainwater, and trim the brown off with scissors following the leaf's own shape.
Spider mites
Dry warm air. Palms are a favourite.

Fix: Shower the fronds, both sides, and treat weekly for a month.
Whole fronds yellowing from the bottom
Normal ageing if one at a time; overwatering if several.

Fix: Cut old fronds off at the base and check the mix is not staying wet.

Propagation

From seed only. A clump can be split, but each piece is an individual seedling and splitting often kills several.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Non-toxic to cats and dogs.

Questions people ask

How often should you water a Kentia palm?

Water every 8 days as a starting point — that is the cadence PlantParlour sets for Howea forsteriana. Keep the top of the compost just barely damp. Palms will not forgive a pot left standing in water, and brown tips are the receipt for the one time you let it dry out hard. Light, pot size and the time of year all move that number, so treat it as a reminder to go and check rather than a rule.
