Also called paradise palm, thatch palm, howea.

About Kentia palm

Howea forsteriana · also called paradise palm, thatch palm · houseplant

Kentia palm is an elegant slow-growing palm from Lord Howe Island with arching dark green fronds. Famously tolerant of low light, dry air, and neglect — once a Victorian parlour favourite. Pet-safe and one of the safest palms to keep with curious cats and dogs.

Howea forsteriana, the kentia palm, is endemic to Lord Howe Island off Australia, a single-trunked feather palm with arching fronds (growers often pot several together for fullness).

Use a well-drained potting mix; the palm dislikes both waterlogging and complete drying out at the roots.

Mature size: 2-3 m indoors

How to tell kentia palm needs repotting

Repotting on a calendar is less reliable than reading the plant. For kentia palm, watch for these signs:

How often to repot kentia palm

Every 2–3 years; top-dress in the in-between years. Kentia palm's growth habit — single-stemmed slow-growing palm — sets the pace.

What size pot to step kentia palm up to

Move up exactly one pot size. A heavy kentia palm dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot kentia palm

Early spring, just as new growth restarts, is the ideal window for kentia palm. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting kentia palm

  1. Consider top-dressing first. If kentia palm is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
  2. Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
  3. Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
  4. Repot at the same depth. Add fresh free-draining loam-based mix beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
  5. Water and leave it put. Water thoroughly, then leave kentia palm in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave kentia palm in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for kentia palm

Kentia palm wants free-draining loam-based mix. Loam compost with 20-25% perlite. Pot up only every 3-4 years; tight roots are fine. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting kentia palm — frequently asked questions

How often should you repot kentia palm?

Every 2–3 years; top-dress in the in-between years for kentia palm. Fully repot kentia palm only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with free-draining loam-based mix. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does kentia palm need?

Move up exactly one pot size. A heavy kentia palm dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot. Use our pot size calculator to size it from the plant's current pot and root spread.

When is the best time of year to repot kentia palm?

Early spring, just as new growth restarts, is the ideal window for kentia palm. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Should you top-dress or fully repot kentia palm?

For a big, heavy kentia palm, top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise kentia palm after repotting?

Not immediately. Wait about 4 weeks after repotting kentia palm. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
