Plumose Soft Shield Fern problems — and how to fix them
Plumose Soft Shield Fern (Polystichum setiferum 'Proliferum') 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.
Frond browning from winter wind
Despite extreme cold hardiness, persistent drying winter winds can scorch and brown the delicate frond tips; site in a sheltered spot or erect a simple windbreak of hessian during harsh spells.
Vine weevil grub damage
Vine weevil larvae feed on roots and rhizomes, causing sudden wilting or collapse of fronds; treat container-grown plants preventatively with a biological nematode drench (Steinernema kraussei) in late summer.
