Troubleshooting
Hoya Krimson Princess problems — and how to fix them
Hoya Krimson Princess (Hoya carnosa 'Krimson Princess') 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.
Yellowing leaves
Almost always a sign of overwatering or poor drainage - let the soil dry out more between waterings and check that the pot drains freely.
Brown, crispy leaf edges
Usually underwatering, low humidity, or sun scorch. Adjust watering, raise humidity, and move the plant out of harsh direct afternoon sun.
Mealybugs
Look for white, cottony masses on stems and leaf undersides. Dab with an alcohol-dipped cotton swab and treat with insecticidal soap; the waxy crevices make Hoyas prone to them.
No flowers
Often too little light or a too-young plant. Provide bright indirect light, allow it to become slightly pot-bound, and be patient - mature plants bloom from spurs.
Cutting off spent flower spurs
Never remove the bare peduncles (spurs) after blooms drop - the plant reflowers from the same spurs year after year, so cutting them off sacrifices future flowers.
