Curly Sentry Palm problems — and how to fix them
Curly Sentry Palm (Howea belmoreana) 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 (Phytophthora)
Overwatering in poorly draining compost is the leading cause of death; fronds yellow from the base upward and the trunk base softens. Remove affected roots, dust with sulphur, repot into fresh dry mix, and reduce watering frequency.
Spider mites in dry air
Central heating below 40% humidity invites spider mite colonies on the undersides of leaflets, causing pale, speckled foliage. Regularly wipe fronds and treat with a dilute neem oil spray at 7-day intervals for three applications.
