Troubleshooting
Wallichiana Fern problems — and how to fix them
Wallichiana Fern (Dryopteris wallichiana) 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.
Browning frond tips
Usually under-watering or dry air; keep the soil evenly moist and lift humidity, especially through heated winter months.
Crown rot
Sitting wet at the collar in cold, poorly drained mix invites rot; add grit and ensure the crown drains freely after watering.
Heat and dryness stress
Unlike tropical ferns it dislikes hot, stuffy rooms; in warm spells move it somewhere cooler and shadier to prevent scorch and wilt.
Vine weevil and fungus gnats
Larvae in moist compost can damage roots; let the surface dry slightly between waterings and inspect the rootball if vigour drops.
