Polystichum X prefers consistently moist soil. Water thoroughly when the top inch of soil begins to dry, ensuring good drainage to prevent waterlogging.

Reduce watering slightly during winter dormancy, but do not allow the soil to become completely dry. Overwatering can lead to root rot.

Prune away any dead, damaged, or yellowing fronds as they appear to maintain the plant's appearance and health. This also helps prevent disease. Use clean, sharp pruners or a knife.

Avoid pruning healthy fronds unless necessary for shaping.

Polystichum X is typically propagated by division of clumps in early spring before new growth emerges. Carefully separate the rhizomes with at least one frond and a few roots.

Pot them in suitable, well-draining potting mix. Alternatively, spores can be used, but this is a slow process.

Repot Polystichum X every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix, preferably one formulated for ferns or containing compost and perlite.

Repot in spring, ensuring the rhizome is at or slightly above the soil surface.
