Polystichum makinoi problems — and how to fix them
Polystichum makinoi (Polystichum makinoi) 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.
Leaf browning
Crisped frond edges indicate sun exposure or dry soil. Relocate to shadier conditions and maintain steady moisture with a leaf-mould mulch.
Crown rot in wet winters
A mushy central crown results from waterlogged soil. Plant on a slight mound or improve drainage so water never sits around the base.
Slug and snail damage
New unfurling croziers are tender and can be grazed. Protect emerging spring growth with barriers or wildlife-safe controls.
Slow establishment
Newly planted or divided ferns can sulk for a season. Keep them moist and shaded and avoid disturbing the roots while they settle.
