Description

Nephrolepis – Sword Fern – There are about 30 species of fast growing evergreen or semi evergreen, epiphytic ferns, in this genus. They occur from rainforest or more open habitats in tropical and subtropical regions worldwide. They have short, erect, rhizomes, with numerous runners. The dense clusters of pinnate, fishbone shaped fronds may be erect, spreading, or pendent. Pinnae are usually linear and simple, but may be divided, forked, or crisp in cultivars, of which there are many. Where not hardy, grow as a houseplant, in warmer climates grow in moist, shady sites among shrubs. Indoors, grow in a mix of 1 part loam, 2 parts sharp sand, and 3 parts leaf mold, in bright filtered light, with moderate to high humidity and good ventilation. In the growing season, water moderately and apply a half strength, balance liquid fertilizer monthly. Water sparingly in winter. Out doors, grow in moderately fertile, moist but well drained, humus rich soil in partial shade. Prone to aerial blight, leaf spots, root rots, spider mites, scale insects, and mealy bugs.
