Troubleshooting
Poet's Narcissus problems — and how to fix them
Poet's Narcissus (Narcissus poeticus) 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.
Narcissus bulb fly
Larvae hollow out bulbs, causing soft, rotten centres. Lift and inspect bulbs at dormancy; destroy affected ones. Firm soil around emerging foliage in spring to deter egg-laying.
Basal rot (Fusarium)
Soft, brown decay at bulb base. Remove and discard affected bulbs; improve drainage and avoid replanting narcissus in the same spot for several years.
Narcissus nematode
Causes distorted, yellowing foliage with dark rings in the bulb cross-section. Lift and hot-water treat (44°C for three hours) or destroy infected stock.
Blind shoots (no flowers)
Often caused by bulbs planted too shallowly, drought during bud formation, or overcrowded clumps. Lift and divide congested clumps every 3-5 years.
Grey mould (Botrytis)
Affects foliage in wet, cold springs. Improve airflow; remove dead or dying leaves promptly; avoid overhead watering.
