Troubleshooting
Bracteate Rhinephyllum problems — and how to fix them
Bracteate Rhinephyllum (Rhinephyllum ebracteatum) 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.
Winter rot
Watering too freely in winter — when temperatures are low and evaporation slow — is the primary cause of loss. Reduce to a bare-minimum watering once every 4–6 weeks in cold months, or withhold entirely.
Mealybugs
Root mealybugs are common in Rhinephyllum. Inspect the root system at repotting (every 2–3 years) and treat with a systemic insecticide drench if white waxy residue is found among the roots.
Failure to flower
Night-scented flowers require a distinct warm, light spring period following a cool, dry winter. Plants kept at uniformly warm temperatures year-round may not set buds. A cooler, drier winter rest of 8–12°C encourages flowering.
