Troubleshooting
Yellow Glacier Lily problems — and how to fix them
Yellow Glacier Lily (Erythronium grandiflorum) 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.
Slug and snail damage
Slugs target the soft emerging shoots in spring. Use organic iron-phosphate pellets or sharp grit around the planting site; the RHS lists slugs as the primary pest of Erythronium.
Corm rot from desiccation or waterlogging
Corms perish quickly if allowed to dry out during storage or in excessively wet, poorly draining soil. Plant immediately on receipt and ensure good drainage is balanced with consistent moisture.
