Hoop Petticoat Daffodil problems — and how to fix them
Hoop Petticoat Daffodil (Narcissus bulbocodium) 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 (Merodon equestris)
Larvae tunnel into bulbs, causing hollow, rotted centres and failure to flower. Inspect bulbs at lifting; destroy infested ones. Cover emerging shoots with fine mesh in spring to prevent adults laying eggs.
Basal rot (Fusarium oxysporum f. sp. narcissi)
Brown, spongy rot starting at the basal plate, often with pink mycelium. Caused by warm, wet soils. Ensure sharp drainage, lift and dry bulbs after dormancy, and discard any showing soft spots.
Failure to flower ('blindness')
Most commonly caused by overcrowding, insufficient summer dormancy, or premature foliage removal. Allow leaves to die back naturally for at least 6 weeks after flowering. Divide congested clumps every 3–4 years.
