Troubleshooting
Autumn Daffodil problems — and how to fix them
Autumn Daffodil (Sternbergia lutea) 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.
Failure to flower
Typically caused by insufficient summer heat and sun to ripen the bulbs, planting too shallow, or moving the bulbs too often. Leave clumps undisturbed for three to four years, and ensure the planting site receives long, hot, dry summers.
Botrytis (grey mould)
Wet, humid conditions during dormancy encourage Botrytis cinerea on stored or in-ground bulbs. Improve drainage, mulch with grit over the planting area, and ensure good air flow around foliage in spring.
