Polystichum neolobatum problems — and how to fix them
Polystichum neolobatum (Polystichum neolobatum) 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.
Frond scorch
Bleached or browned fronds follow too much sun or drought. Site in deeper shade and keep the root zone mulched and evenly moist.
Winter crown rot
Waterlogged soil rots the central crown. Ensure sharp drainage with grit and avoid planting in spots where water collects in winter.
Sharp pinnae
The spine-tipped leaflets can prick when handling or weeding nearby. Wear gloves and site away from paths where people or pets brush past.
Vine weevil
Root-feeding larvae cause unexplained wilting and adults notch frond edges. Apply nematodes in late summer or inspect the rootball when dividing.
