Troubleshooting
Superb Stelis problems — and how to fix them
Superb Stelis (Stelis superbiens) 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 poor drainage
Roots sitting in soggy medium quickly rot, turning brown and mushy. Use a very open potting mix or mount the plant, and ensure pots drain freely. Remove dead roots promptly and treat with a fungicide drench.
Failure to bloom
Stelis superbiens often requires a slight cool and dry rest period in autumn-winter to initiate flowering. If temperatures remain uniformly warm, blooming may be skipped. Reduce watering and lower night temperatures to 10–13°C for 4–6 weeks.
Mealybugs
White waxy clusters appear in leaf axils and at the base of racemes. Treat with a cotton swab dipped in rubbing alcohol or an insecticidal soap spray. Check weekly and repeat treatment until clear.
