Ceylon Date Palm problems — and how to fix them
Ceylon Date Palm (Phoenix pusilla) 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.
Lethal yellowing (phytoplasma disease)
A systemic phytoplasma disease spread by leafhopper insects. Premature fruit drop, frond yellowing from the lower canopy upward, and eventual spear-leaf collapse are diagnostic. No cure; preventive oxytetracycline trunk injections offer protection in endemic areas.
Spider mites in dry conditions
Fine webbing on frond undersides with stippled, bronzed leaflets indicates mite infestation. Increase humidity, rinse fronds with water, and apply insecticidal soap or miticide. Outbreaks intensify under hot, dry conditions.
Crown rot from poor drainage
Despite enjoying moisture, stagnant water at the root zone promotes Phytophthora root and crown rot. Fronds collapse centrally. Improve drainage, reduce watering, and apply a preventive copper-based fungicide to soil in early stages.
