Hoya Bilobata problems — and how to fix them
Hoya Bilobata (Hoya bilobata) 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 leaves or stem dieback
Usually caused by overwatering or a heavy, poorly draining mix that keeps the roots soggy; let the mix dry further and improve drainage.
Shrivelled or wrinkled leaves
A sign of underwatering or roots that have dried out completely; rehydrate gradually and check that water is reaching the rootball.
Leggy stems with sparse leaves and no flowers
Indicates too little light; move to a brighter spot with more bright, indirect light to tighten growth and encourage blooming.
Blackened leaves or grey mould (Botrytis)
Brought on by cold, damp conditions or persistently wet foliage; keep the plant warm, improve airflow, and avoid misting this species.
Mealybugs and spider mites
The dense foliage hides cottony mealybugs and mites that cause stippling; inspect leaf joints and treat with insecticidal soap or diluted neem oil.
Failure to bloom
Often simply immaturity or insufficient light, and sometimes from removing the old flower spurs (peduncles), which re-bloom each year — never cut them off.
