Troubleshooting
Alpine Woodsia problems — and how to fix them
Alpine Woodsia (Woodsia alpina) 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.
Crown rot from waterlogging
The most common cause of death in cultivation; the compact rhizome rots rapidly in soggy soil. Position the crown just above the soil surface surrounded by grit, and ensure the container or bed drains freely.
Heat stress and dormancy disruption
Being an alpine species, Woodsia alpina dislikes warm temperatures above about 22°C (72°F) and may go prematurely dormant in a hot, dry summer; site in a cool, partially shaded spot and mulch the root zone with fine grit to keep roots cool and moist.
