Keep the soil consistently moist but not waterlogged. Trichomanes alatum thrives in high humidity and prefers to have its roots in damp conditions. Water when the top layer of soil begins to feel dry to the touch.

Avoid letting the plant dry out completely, as this can be detrimental to its delicate fronds.

Pruning is generally minimal for Trichomanes alatum. Remove any dead, damaged, or yellowing fronds as they appear to maintain the plant's aesthetic appeal and health.

This can be done with clean, sharp scissors or pruning shears. Early removal of unhealthy foliage prevents potential disease spread.

Propagation is typically done through division of established plants or by spores. For division, carefully separate sections of the rhizome with fronds attached.

Spore propagation requires specific, sterile conditions and patience, mimicking the plant's natural reproduction cycle in a humid environment.

Repot Trichomanes alatum every 2-3 years, or when it becomes root-bound. Use a well-draining, peaty potting mix. Ensure the new pot is only slightly larger than the current one.

Repotting is best done in spring before active growth begins. Handle the delicate roots with care during the process.
