Cuming's Medinilla problems — and how to fix them
Cuming's Medinilla (Medinilla cumingii) 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.
Mealybugs
White cottony clusters appear in leaf axils and at the base of flower stalks. Treat promptly by dabbing with isopropyl alcohol, then applying insecticidal soap or neem oil every 7–10 days for several weeks.
Leaf scorch / tip browning
Brown leaf tips and edges result from low humidity, direct harsh sun, or fluoride/salt build-up in the soil. Raise humidity, move out of direct sun, and flush the pot with plain water monthly.
No flowers
Like other medinillas, M. cumingii benefits from a cool, drier winter rest at around 18 °C (65 °F) to initiate the next season's blooms. Without this rest phase, the plant may remain vegetative.
