Keep the soil consistently moist but not waterlogged. Water thoroughly when the top centimeter of soil begins to feel dry. Avoid letting the plant sit in standing water, which can lead to root rot.

Reduce watering slightly during cooler months, but never allow the soil to dry out completely.

Remove any dead, damaged, or discolored fronds as they appear to maintain a tidy appearance and encourage new growth. Trim back leggy growth to encourage a fuller, more compact form.

Pruning can be done at any time of year, but is best performed in spring before new growth emerges.

Blechnum punctulatum can be propagated by division or from spores. Divisions are best taken in spring when repotting. Gently separate the rhizomes, ensuring each division has healthy roots and fronds.

Spore propagation is slower and requires specific conditions, making division the more common method.

Repot every 2-3 years or when the plant becomes root-bound, preferably in spring. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.

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