Rusty woodsia (Woodsia ilvensis)

Rusty woodsia

Also known as: Rusty cliff fern

Found in cool, forested regions, rusty woodsia was once so popular with collectors that it has become endangered in the United Kingdom and certain parts of the US. Rusty woodsia grows on cliff sides, rocks, and sometimes terrestrially, and the silvery undersides of its fronds turn a rust color in autumn, giving it its name.

Water: Rusty woodsia thrives in temperate forest understories, requiring consistent humidity and organic-rich soil. It prefers evenly moist conditions with moderate drought tolerance. Weekly watering is essential for health, and rainwater enhances nutrient uptake and foliage quality.

Fertilize: For rusty woodsia, apply balanced fertilizers quarterly to enhance growth and health. Use modest amounts based on guidelines, especially during spring and summer. Opt for diluted solutions to prevent root burn and avoid over-fertilization to maintain optimal nutrient levels.

Pruning: Rusty woodsia is a hardy fern with rust-colored scales. Prune in early to late spring, removing dead fronds to promote growth. Clear old foliage to prevent disease and improve air circulation. Avoid heavy pruning to maintain its robust and natural appearance.

Propagation: Rusty woodsia is a small, clump-forming fern from the Woodsia genus. Propagation is best done through division, ensuring each section includes part of the rhizome. Replant at the same depth in well-draining substrate, maintaining consistent moisture for successful establishment.
