Troubleshooting
Candy Corn Plant problems — and how to fix them
Candy Corn Plant (Nematanthus strigillosus) 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.
Failure to bloom
Most commonly due to low light or an oversized pot. Increase light levels and keep the plant slightly pot-bound; a short cooler rest in winter can also trigger flowering.
Leaf drop
Sudden temperature drops, cold draughts, or overwatering cause leaf drop. Keep above 16°C and avoid exposure to cold windows in winter.
Root rot
Overwatering in heavy mix is the primary cause of plant decline. Repot into a free-draining mix and adjust the watering schedule.
Mealybugs
Common in the crevices of stems and leaf axils. Treat with isopropyl alcohol and follow up with neem oil spray weekly.
Yellowing leaves from fluoride
Fluoride in tap water causes marginal leaf yellowing and tip browning. Use filtered, rainwater, or allow tap water to sit overnight before use.
