Keep the substrate consistently moist, but not waterlogged. Use distilled, rainwater, or reverse osmosis water to prevent mineral buildup. Allow the surface to dry slightly between waterings during cooler periods.

Avoid letting the soil dry out completely.

Pruning is rarely necessary. Remove any dead or yellowing fronds at the base to maintain a tidy appearance and prevent potential fungal issues. Use clean, sharp scissors.

Propagation is typically done through division of established clumps during repotting. Spores can also be used, but this method is more challenging and requires specialized conditions.

Repot Trichomanes membranaceum annually or when it outgrows its current container. Use a well-draining, peat-based potting mix. Handle the delicate roots gently during the process.
