Troubleshooting
Spider Brake Fern problems — and how to fix them
Spider Brake Fern (Pteris multifida) 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
Dryness at the roots or very dry air crisps the fine pinnae; keep the soil evenly moist and lift humidity in heated rooms.
Sparse, thin growth
Too little light or an exhausted, rootbound pot thins the clump; brighten the position and pot on or divide every couple of years.
Self-sown seedlings
Free-floating spores germinate in neighbouring pots and damp masonry; harmless but easy to weed out if unwanted.
Cold damage
Though tolerant of cool rooms, hard frost blackens the fronds; in marginal climates protect or overwinter it under cover.
