About Curly Kentia Palm
Howea belmoreana · also called curly kentia, belmore sentry palm · houseplant
The curly kentia (Howea belmoreana) is the more compact, gracefully arching cousin of the classic kentia palm, native to Lord Howe Island. Its fronds curve elegantly inward, giving a softer, fountain-like crown. Slow-growing, shade-tolerant and remarkably forgiving, it is a refined, long-lived indoor palm prized for its elegance and durability in low light.
Preferred mix: Free-draining, loam-based potting mix
Watch for — Brown frond tips: From dry air, underwatering or fluoride and salts in tap water. Raise humidity, water with filtered or rainwater and flush the soil to remove salts.
Why curly kentia palm needs this mix
Curly Kentia Palm is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Curly 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.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons curly 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 curly 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 curly kentia palm.
