Troubleshooting
Tasmanian Holly Fern problems — and how to fix them
Tasmanian Holly Fern (Polystichum proliferum) 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.
Scorched fronds
Direct sun or hot, dry positions bleach and crisp the foliage; move to shade and keep the rootball cool and moist.
Crown rot
Soggy soil around the crown rots this otherwise tough fern; ensure sharp drainage at the collar and avoid standing water in the saucer.
Tatty old fronds
Evergreen fronds gradually brown with age; cut them away at the base in early spring to let fresh croziers emerge cleanly.
Slugs and snails outdoors
Young unfurling fronds are grazed by molluscs in shaded gardens; protect emerging croziers in spring with barriers or traps.
