Troubleshooting
Hoya sigillatis problems — and how to fix them
Hoya sigillatis (Hoya sigillatis) 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 common killer. Yellowing, mushy stems or sudden leaf drop usually mean the roots have stayed too wet. Use a chunky mix, a pot with drainage, and let the medium dry before watering again.
Shrivelled, puckered leaves
Deep wrinkling signals underwatering or, paradoxically, rotted roots that can no longer take up water. Check the roots first; if firm, give a thorough soak and the leaves should plump back up.
Mealybugs and scale
Hoyas attract mealybugs, scale, aphids and spider mites, which hide in leaf joints and on undersides. Inspect regularly and treat with insecticidal soap or neem oil, repeating every 7-10 days until clear.
No flowers
Sigillatis blooms only with enough bright light and maturity. Never remove the old flower spurs (peduncles) — they rebloom from the same point year after year. Slightly pot-bound plants in bright light flower best.
Loss of leaf colour
Reddish-brown 'sun stress' fades and silver flecking dulls in low light. Move it brighter (without harsh direct sun) to restore the burgundy tones collectors prize; conversely, scorched pale patches mean too much direct sun.
