Sword Fern: Nephrolepis exaltata
Ideal and resilient fern for indoors, with long, tapering, usually erect fronds and several attractive forms (see sidebar).
Height: 1 ½–2 ½ft (45–75cm) |
Spread: 1 ½–3ft (45–90cm) |
Winter: 50–55°F (10–13°C). Direct light without full sun |
Summer: 55–64°F (13–18°C). Direct light without full sun, or indirect light |
Care: In winter, keep compost slightly moist; in summer, water freely and feed every 2–3 weeks with weak liquid fertilizer. Repot in spring when roots fill the pot, usually every 2–3 years. When already in a large pot, tease away some of the compost and repot into a same-sized pot, adding some fresh compost. |
