Troubleshooting
Hoya Coriacea problems — and how to fix them
Hoya Coriacea (Hoya coriacea) 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.
Root rot from heavy soil or overwatering
The big root system suffocates in dense or constantly wet mix; use a very coarse medium and let it dry between waterings.
Insufficient light limits flowering
This large hoya needs strong indirect light to bloom; in dim spots it grows leaves but rarely flowers.
Outgrowing its support
It is a vigorous climber that quickly overwhelms small trellises; provide a tall, sturdy support and prune to shape rather than removing flowering spurs.
Mealybugs
Cottony pests hide along stems and leaf undersides; treat promptly with alcohol or insecticidal soap and check new growth.
