Solitary Fishtail Palm problems — and how to fix them
Solitary Fishtail Palm (Caryota urens) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Spider mites
Common in dry air; treat with insecticidal soap or neem oil and raise humidity.
Brown leaf tips
Usually caused by low humidity, fluoride in tap water, or underwatering; switch to filtered water and mist regularly.
Root rot
Result of waterlogged soil; ensure the pot has drainage holes and allow the topsoil to dry between waterings.
Scale insects
Appear as brown bumps on stems; remove manually or treat with horticultural oil.
Monocarpic die-back
After flowering the trunk dies naturally; this is a normal life-cycle event, not a disease.
