Troubleshooting
Christmas Fern problems — and how to fix them
Christmas Fern (Polystichum acrostichoides) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Brown or tattered winter fronds
Largely cosmetic. Trim spent fronds at the base in early spring before new croziers unfurl to keep the clump tidy.
Scorched fronds in sun
Direct sun damages this shade-lover. Move to dappled or full shade.
Drying out during establishment
Young plants need steady moisture the first season. Water through droughts until the deep root system develops.
Crown rot in heavy wet soil
Poor drainage rots the crown. Plant on slopes or improve drainage with grit and organic matter.
