Troubleshooting
Pale Yellow Fritillary problems — and how to fix them
Pale Yellow Fritillary (Fritillaria pallidiflora) 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.
Waterlogged soil
Prolonged waterlogging causes bulb rot. Improve drainage with organic matter or plant on a slight slope.
Lily beetle
Scarlet lily beetles attack foliage and flowers. Inspect plants regularly and remove adults and larvae by hand or treat with an appropriate insecticide.
Poor or no flowering
Often caused by overcrowding after several years. Lift and divide the clump in late summer every 3–4 years to reinvigorate.
Slug damage
Emerging shoots susceptible in early spring. Apply a grit mulch and use organic slug controls as needed.
Botrytis
Grey mould can affect foliage in cool wet springs. Ensure good air circulation and remove any affected tissue promptly.
