Keep the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out slightly between waterings. Reduce watering frequency during winter months.

Ensure good drainage to prevent root rot, which is a common issue with ferns.

Prune away any dead, brown, or damaged fronds at their base to maintain a tidy appearance and encourage new growth. This can be done at any time of year. Remove any spent fronds to prevent them from becoming unsightly.

Polypodium ferns can be propagated by division of rhizomes or by spores. Divide overgrown clumps in spring, ensuring each section has healthy rhizomes and fronds.

Spore propagation is more complex and requires specific conditions.

Repot every 2-3 years, or when the plant becomes root-bound. Use a well-draining, peaty potting mix. Repot in spring before new growth begins.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
