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.
Preferred mix: Free-draining loam-based mix
Watch for — Yellow fronds: Overwatering; reduce frequency and check drainage.

Why kentia palm needs this mix
Kentia palm is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Kentia palm is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons kentia palm struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates kentia palm's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for kentia palm.
pH — does it matter for kentia palm?
Kentia palm is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A decent bagged houseplant compost works for kentia palm as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all kentia palm needs — the free-draining mix does the rest.
Refresh kentia palm's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for kentia palm covers the timing and technique step by step.
Kentia palm soil — frequently asked questions
What is the best soil mix for kentia palm?
Use 2 parts potting soil to 1 part perlite to 1 part coarse sand. Kentia palm is native to Lord Howe Island's fast-draining sandy soils, so drainage matters more than richness — a mix that stays loose and never waterlogged prevents the root rot this species is highly prone to indoors.
Can I use normal potting soil for kentia palm?
Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates kentia palm's roots. A decent bagged houseplant compost works for kentia palm as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Does kentia palm need a special pH?
Aim for pH 6.0–6.8 (slightly acidic to near-neutral). Below 6.0 fluoride becomes freely available to roots and causes the brown leaf-tip burn Kentias are notorious for; above 7.0 manganese uptake is impaired (noted by UF/IFAS). Soften if testing shows your tap water is low in fluoride.
Should I buy a bagged mix or make my own for kentia palm?
A decent bagged houseplant compost works for kentia palm as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
How often should I refresh the soil for kentia palm?
Refresh kentia palm's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. A pot with a drainage hole and a saucer you empty after watering is all kentia palm needs — the free-draining mix does the rest.
