Fritsch's Goldfish Plant problems — and how to fix them
Fritsch's Goldfish Plant (Nematanthus fritschii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leggy, non-blooming stems
Insufficient light is the primary cause; move the plant to a brighter position or provide supplemental grow lighting, and pinch stem tips in late winter to encourage branching and more flowering shoots.
Spider mites
Low humidity encourages spider mite infestations, visible as fine webbing on the undersides of leaves; raise humidity above 50% and treat with a dilute insecticidal soap spray.
