Keep the soil consistently moist but not waterlogged. Ophioglossum polyphyllum prefers a humid environment. Water thoroughly when the top layer of soil begins to feel dry.

Avoid letting the soil dry out completely, especially during active growth. Reduce watering slightly in cooler, dormant periods.

Pruning is generally not required for Ophioglossum polyphyllum. Remove any dead or yellowing leaves as they appear to maintain a tidy appearance and prevent potential disease.

This can be done with clean, sharp scissors or pruning shears at any time of year.

Propagation is typically done by division. Carefully separate the rhizomes during repotting. Each division should have at least one frond and a healthy portion of the rhizome.

Plant the divisions in well-draining potting mix and keep consistently moist until established.

Repot Ophioglossum polyphyllum every 2-3 years or when the plant becomes root-bound. Spring is the ideal time for repotting, just as new growth begins.

Use a well-draining potting mix, such as a blend of peat moss, perlite, and a small amount of compost.
