Dickie's Bladder Fern problems — and how to fix them
Dickie's Bladder Fern (Cystopteris dickieana) 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.
Desiccation in dry conditions
The thin-textured fronds wilt and brown rapidly if the rootball dries out or if the plant is exposed to drying winds. Keep moisture consistent and shelter from wind; in a rock garden, position between moist rocks that act as a moisture reservoir.
Slug damage to emerging fronds
Young croziers unfurling in spring are particularly vulnerable to slug grazing. Apply iron phosphate slug pellets around the crown in early spring, or place grit around the base as a deterrent.
