Naumann's Wax Plant problems — and how to fix them
Naumann's Wax Plant (Hoya naumannii) 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
White, waxy insects congregate at leaf axils and stem nodes, sucking sap and causing stunted growth. Wipe affected areas with isopropyl alcohol on a cotton bud and treat with insecticidal soap or neem oil; repeat weekly until clear.
Failure to bloom
Insufficient light is the primary reason Hoya naumannii refuses to flower. Move to a brighter location and ensure peduncles (flower spurs) are never removed — blooms re-emerge from the same spur each year.
