Troubleshooting
Hoya Pubicalyx 'Royal Hawaiian Purple' problems — and how to fix them
Hoya Pubicalyx 'Royal Hawaiian Purple' (Hoya pubicalyx 'Royal Hawaiian Purple') 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.
Won't bloom
The main complaint with this prized cultivar. It needs bright indirect light, a slightly pot-bound pot, and intact old peduncles — never cut off the spent flower stubs, as next year's blooms emerge from the very same spurs.
Root rot from wet feet
Soft, blackening stems and dropping leaves follow overwatering. Use the chunky mix, let it dry well between drinks, and guarantee drainage; the succulent leaves make drought far safer than sogginess.
Bud blast
Forming buds shrivel and drop if the plant is moved, suddenly dried out, or chilled. Keep conditions stable once an umbel is developing and don't reposition the plant mid-bloom.
Mealybugs and scale
Sap-suckers lodge in leaf axils and along stems. Spot-treat with isopropyl alcohol and repeat; inspect the dense growth regularly to catch infestations early.
