Large-perianth Goldfish Plant problems — and how to fix them
Large-perianth Goldfish Plant (Nematanthus perianthomegus) 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
Wilting despite moist soil, mushy stem bases, and brown roots signal rot; repot into fresh dry mix and reduce watering frequency immediately.
Failure to flower
Insufficient light is the most common cause; move to a brighter spot and ensure a slight temperature drop at night (around 16°C) to stimulate bud set.
Mealybugs
White cottony clusters appear in leaf axils; remove manually with a cotton bud dipped in isopropyl alcohol and follow up with insecticidal soap spray.
