Troubleshooting
Hoya Retusa problems — and how to fix them
Hoya Retusa (Hoya retusa) 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 overwatering
The most frequent killer. Soggy, dense soil rots the roots, causing yellow, mushy leaves. Let the mix dry between waterings and use a fast-draining, airy blend.
Yellowing leaves
Usually signals overwatering or, less often, too much harsh direct sun. Check soil moisture first and adjust watering or move out of intense light.
Spider mites and aphids
Common pests on the thin foliage. Watch for fine webbing or sticky honeydew, then rinse and treat with insecticidal soap or neem oil.
Refusing to bloom
Almost always insufficient light or humidity. Move to a brighter indirect spot and never cut off the old flowering spurs (peduncles) — new blooms form on them.
Shrivelled, wrinkled leaves
A sign of underwatering or root damage. Check whether roots are healthy, then water more consistently once the top of the mix dries.
Leggy, sparse growth
Low light causes stretched, thin vines with wide gaps between leaves. Increase light and pinch back to encourage bushier growth.
