Rough sword fern (Nephrolepis hirsutula)

Rough sword fern

Rough sword fern is a lush fern with long, arching fronds covered with small, delicate leaflets. Its leaflets are finely toothed, contributing to a feathery appearance. The underside of each frond exhibits sporangia that appear as round sori, crucial for reproduction. Rough sword fern thrives in moist, shaded environments, where its dense, green foliage can form extensive clusters, enhancing ground cover and forest diversity.

Water: Rough sword fern thrives in humid tropical regions and prefers consistent moisture. Weekly watering is ideal, reflecting its natural habitat. As an evergreen typically grown indoors, regular misting helps maintain the necessary humidity for optimal growth.

Fertilize: Rough sword fern requires tailored fertilization based on age and soil type. Recently potted plants need little nourishment. Use a general all-purpose fertilizer (20-10-20) monthly for humus-rich soil or bi-monthly for sandy-loamy substrates as the plant matures.

Pruning: Rough sword fern thrives with proper pruning, which involves removing dead fronds during its active growth in early to late spring. This prevents overcrowding, enhances light circulation, and promotes healthy growth. Clean cuts minimize disease risks, contributing to a robust plant appearance.

Propagation: Rough sword fern can be propagated effectively through cuttings taken below the leaf node. Use well-draining soil and maintain consistent moisture, warmth, and indirect light for optimal growth. This approach aids in establishing a strong root system, supporting the ferns' vigorous development.

Repotting: Repot rough sword fern every 2-3 years in spring, using wide, shallow pots. After repotting, keep rough sword fern in indirect light and maintain consistent moisture. Avoid disturbing its delicate fronds for optimal health.
