Ceratopteris cornuta thrives in consistently moist to waterlogged conditions. For potted specimens, keep the soil saturated, mimicking its natural marshy habitat.

Avoid letting the substrate dry out completely, as this can stress the plant. Frequent watering is essential, especially during warmer periods.

Pruning is minimal for Ceratopteris cornuta, primarily involving the removal of dead or yellowing fronds. Use clean, sharp scissors or pruning shears to make a clean cut at the base of the frond.

This helps maintain the plant's aesthetic appeal and prevents potential disease spread.

Propagation is easily achieved through spores or by division. Spores are microscopic and require specific conditions to germinate.

Alternatively, mature plants can be gently divided into smaller sections, each with healthy roots and fronds, and repotted separately.

Repot Ceratopteris cornuta when it becomes root-bound or outgrows its current container, typically every 1-2 years. Use a well-draining potting mix, ideally with added organic matter.

Ensure the new pot is slightly larger than the old one to allow for continued growth.
