Pierre's Stephania problems — and how to fix them
Pierre's Stephania (Stephania pierrei) 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.
Caudex rot
Overwatering during dormancy or poor drainage are the primary causes of this fatal condition. The caudex softens and collapses. Prevention is the only reliable strategy: withhold water entirely from leaf drop to spring bud break and grow in very well-drained soil.
Leaf scorch
Direct summer sun through glass can scorch the peltate leaves, producing brown patches. Move slightly further from the window or filter light with a sheer curtain.
Mealy bugs
Congregate at leaf axils and in the crown near the caudex. Treat small outbreaks with 70% isopropyl alcohol on a cotton swab. For persistent infestations, use a systemic insecticide appropriate for ornamental houseplants and repeat after 10 days.
