Long-leaf Parlour Palm problems — and how to fix them
Long-leaf Parlour Palm (Chamaedorea oblongata) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from overwatering
Chamaedorea oblongata is notably sensitive to waterlogged compost; yellowing lower fronds followed by stem softening at the base are early warning signs — improve drainage and reduce watering immediately.
Mealybugs
White cottony clusters can appear in leaf axils and along the midrib; remove manually with a cotton swab dipped in rubbing alcohol, then apply neem oil spray as a follow-up treatment.
