Troubleshooting
Flexuose Nerine problems — and how to fix them
Flexuose Nerine (Nerine flexuosa) 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.
Failure to flower
Most commonly caused by: burying the bulb too deep (neck must be at or above soil level), too much shade, or disturbing the roots. Leave established bulbs undisturbed for years.
Wet summer rot
The overriding cause of failure in UK gardens. Grow at the base of a sunny south-facing wall under the roof overhang, or in a greenhouse for summer.
Mealy bug
White waxy clusters in the leaf axils. Treat with neem oil or systemic insecticide; isolate affected pots.
Frost damage to flower buds
Emerging autumn spikes can be caught by early frosts. Fleece in hard frost warnings or grow in a cold greenhouse in colder regions.
