King Alfred Daffodil problems — and how to fix them
King Alfred Daffodil (Narcissus pseudonarcissus 'King Alfred') 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)
One of the most damaging pests of large-bulb narcissus. Grubs hollow out bulbs, causing failure to emerge or single, weak, grass-like leaves. Inspect bulbs at lifting; destroy any that feel light and soft. Cover planted areas with insect-proof mesh in spring.
Ink disease (Mystrosporium adustum)
Black streaks or blotches on the outer bulb scales and roots, causing reduced vigour or failure. More common in poorly drained soils. Lift and destroy affected bulbs; improve drainage and rotation in the planting area.
Clump congestion and declining flower size
'King Alfred' naturalizes so vigorously that clumps become overcrowded within 5–7 years, resulting in smaller, fewer flowers. Lift and divide clumps every 4–5 years immediately after foliage dies down; replant offset bulbs at the correct depth in refreshed soil.
