Stenake's Wax Plant problems — and how to fix them
Stenake's Wax Plant (Hoya stenakei) 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.
Mealybugs and scale insects
Both pests are common on waxy-leaved hoyas; mealybugs leave a white cottony residue in stem joints while scale appears as brown bumps on stems. Treat with isopropyl alcohol on a cotton swab followed by insecticidal soap or neem oil.
Leaf yellowing from cold draughts
H. stenakei is sensitive to temperatures below 15°C and cold air from windows or air conditioning units; sudden chilling causes yellowing and leaf drop. Keep away from draughts and maintain steady warmth above 18°C.
