Water: Coastal woodfern thrives in humid forests and prefers consistent moisture, requiring weekly watering to maintain lush foliage. This evergreen plant retains water in its fronds, allowing it to stay vibrant through varying seasonal rainfall patterns, although it can tolerate short dry periods.

Fertilize: Coastal woodfern thrives with biannual balanced fertilizer applications in spring and autumn, promoting lush growth. Use diluted solutions to avoid root burn and adjust according to label guidelines during active growth. Apply on moist soil to protect coastal woodfern's delicate fronds.

Pruning: Coastal woodfern thrives in shaded areas with minimal pruning required. Perform pruning in early to late spring, removing dead fronds to enhance airflow and appearance. Avoid cutting the central crown. Regular checks for dead foliage ensure coastal woodfern remains healthy and vigorous throughout the year.

Propagation: Coastal woodfern can be multiplied by collecting spores and surface-sowing them on sterilized medium with indirect light and consistent moisture. Germination is gradual, requiring a humid environment to develop gametophytes into mature ferns. Patience is essential during this delicate cultivation process.
