Troubleshooting
Braun's Holly Fern problems — and how to fix them
Braun's Holly Fern (Polystichum braunii) 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
The primary problem in cultivation; wet, poorly drained soils — particularly in warm weather — cause the crown to rot, resulting in frond collapse; plant with the crown at or just above soil level, ensure good drainage, and avoid mulching directly over the crown.
Frond browning in heat and drought
Leaf tips and margins brown and become papery when temperatures are high, the soil dries out, or the plant is exposed to hot afternoon sun; site in a cool, shaded position, mulch generously, and water consistently during any dry spells in summer.
