How to prune brittle maidenhair fern

Any time for dead-frond tidying; early spring if cutting back after full die-back. Remove dead stems at soil level with clean scissors. After full die-back, cut all stems to the base, water consistently and maintain humidity above 50% to encourage regrowth.

As needed. Brittle Maidenhair Fern (Adiantum tenerum) rarely needs pruning beyond removing dead or crisped fronds. Cut spent stems cleanly at the base. If the entire plant dies back from low humidity or drought, cut all growth to soil level — it often regrows from the rhizome when watering resumes. No shaping required.
