Troubleshooting
Royal Red Lipstick Plant problems — and how to fix them
Royal Red Lipstick Plant (Aeschynanthus pulcher) 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.
Sparse or no flowers
Usually caused by low light or pot-bound avoidance (this plant PREFERS to be slightly root-bound). Ensure bright indirect light and a cool, drier winter rest of 6-8 weeks to stimulate bud set.
Root rot
Most common cause of decline. Remove from the pot, trim any brown mushy roots, and repot into fresh free-draining mix. Reduce watering frequency going forward.
Mealybugs
Cottony clusters at leaf axils. Treat with isopropyl alcohol on a cotton bud and follow up with diluted neem oil spray every 5-7 days until eradicated.
Cold damage
Temperatures below 15°C cause leaf yellowing and drop. Keep away from cold windows and draughts, especially in winter.
Bud drop
Sudden environmental changes — moving the plant, cold draughts, or dramatic watering changes during bud development — can cause buds to drop. Keep conditions stable once buds form.
