Bird-in-a-bush problems — and how to fix them
Bird-in-a-bush (Corydalis solida) 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 in waterlogged soil
Solid corms are particularly susceptible to fungal rot during summer dormancy if kept wet; ensure sharp drainage or lift and store corms dry in sand until autumn replanting.
Slugs and snails on emerging shoots
The tender young growth emerging in late winter is highly attractive to slugs; apply wildlife-safe iron phosphate pellets or use grit mulch around the crown at first emergence.
