Troubleshooting
Hoya Rosita problems — and how to fix them
Hoya Rosita (Hoya rosita) 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.
Overwatering and root rot
The most likely cause of decline; this hybrid is very sensitive to wet soil. Let the top inches dry fully and use a chunky, free-draining mix.
No flowers
Insufficient light or too much disturbance. Give bright indirect light, let the soil dry between waterings, and don't move the plant once buds form, as this causes bud drop.
Loss of red leaf colour
Bronze and rosy tones fade in low light. Move to a brighter spot with some gentle direct sun to restore the stress colouration.
Mealybugs
Common on hoyas, hiding in leaf joints. Check new growth regularly and dab pests with 70% isopropyl alcohol or treat with insecticidal soap.
