Troubleshooting
Fischer's Wax Plant problems — and how to fix them
Fischer's Wax Plant (Hoya fischeriana) 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.
Root rot from overwatering
The most common cause of decline in this species. Yellowing lower leaves and soft, darkened stems at soil level indicate root rot. Remove from the pot, cut away mushy roots, allow to dry briefly, and repot into a very free-draining fresh mix.
Mealybugs on stems and leaf axils
White, fluffy deposits at stem joints and in leaf axils are a frequent problem. Treat promptly by dabbing with rubbing alcohol on a cotton bud, then apply neem oil or insecticidal soap every 7–10 days until no further insects are visible.
Failure to flower
Insufficient light and removal of old peduncles are the main causes. Ensure the plant receives bright indirect light for at least 5–6 hours daily, and never remove spent flower stalks as Hoya fischeriana reblooms from the same spurs each season.
