Kentia Palm problems & how to fix them
Howea forsteriana
Drooping, yellowing, brown tips, or a plant that just won’t thrive? Here are the most common Kentia Palm problems, what usually causes them, and how to turn things around.
Common problems
Overwatering
Its biggest risk — slow growth means slow water use, and wet soil rots the roots. The soil is staying wet longer than the plant can handle, starving roots of oxygen. If caught before roots start rotting, the fix is simple - let the soil dry out and adjust the routine - and most plants bounce back within 2-3 weeks.

Spider mites
Dry heated air lets mites speckle and dull the leathery fronds. Tiny sap-sucking mites that thrive in warm, dry air and leave fine webbing and speckled leaves. Caught early they are very treatable; most plants recover fully within 3-4 weeks of consistent treatment.

Crispy tips (low humidity)
Salty water and low humidity brown the tips, though less than on most palms. Brown, dry leaf tips caused by air that is too dry for the plant, common in heated or air-conditioned rooms. Existing crispy tips never turn green again, but with higher humidity new growth should come in clean within a few weeks.
Scale insects
Brown limpet-like bumps along frond midribs on long-lived specimens. Sap-sucking insects that hide under hard, shell-like bumps stuck to stems and leaves, making them resistant to sprays. Treatment is mostly manual and takes patience, but most plants recover well over 4-6 weeks of consistent removal.

The mistakes that most often kill it
- Overwatering a slow-growing plant in a big decorative pot with no drainage.
- Frequent repotting that wrecks its sensitive roots.
- Placing it in hot direct sun, which permanently scorches the fronds.
