Troubleshooting
String Bean Hoya problems — and how to fix them
String Bean Hoya (Hoya shepherdii) 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 or dropping leaves
Usually overwatering or soggy soil; let the mix dry almost fully between waterings.
Shrivelled, puckered leaves
Underwatering — the succulent leaves draw on stored water, so give a thorough soak.
Mushy stems and root rot
Caused by poor drainage or constant moisture; repot into airy, fast-draining mix and salvage healthy cuttings.
No flowers
Too little light, or the flower spur (peduncle) was cut off. Move to brighter indirect light and never remove old peduncles — blooms return from the same spur.
Mealybugs, scale and spider mites
Wipe pests off with an alcohol-dipped swab, then treat with insecticidal soap every 7-10 days until clear; check leaf backs, nodes and peduncles.
Leaf scorch
Bleached or browned patches from harsh direct midday sun; move to bright indirect light.
