Blunt-Leaf Wax Plant problems — and how to fix them
Blunt-Leaf Wax Plant (Hoya obtusifolia) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Failure to flower indoors
The most common frustration with H. obtusifolia is its refusal to bloom under standard indoor photoperiods. Simulating the natural shortening of days — reducing light exposure to around 12 hours from late summer — is key to triggering bud set.
Fungal root problems
Dense or water-retaining potting media quickly leads to root and base stem rot. Use an open, coarse substrate (charcoal, pumice, orchid bark) and never allow the plant to sit in standing water.
