Troubleshooting
White Trout Lily problems — and how to fix them
White Trout Lily (Erythronium albidum) 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.
Corm rot / failure to establish
Corms desiccate fatally within days of lifting; plant immediately on receipt and keep soil moist. Prolonged waterlogging in winter can also cause rot — good drainage is essential.
Slug and snail damage
Emerging shoots and soft leaves are highly attractive to slugs in early spring; use iron-phosphate pellets or copper barrier tape around planting areas, particularly in mild, wet springs.
