Corn-Leaf Pitcairnia problems — and how to fix them
Corn-Leaf Pitcairnia (Pitcairnia maidifolia) 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.
Leaf tip browning
Results from low humidity, fluoride or chlorine in tap water, or irregular watering. Switch to rainwater and maintain humidity above 60%.
Root rot
Overwatering combined with a poorly draining substrate causes root and crown rot. Ensure the mix dries slightly at the surface between waterings.
Mealybugs
Can nest in the tight leaf axils. Inspect regularly and treat with a cotton swab dipped in rubbing alcohol or a diluted neem-oil solution.
