How to care for bird's nest fern (Asplenium nidus)

Asplenium nidus · Nest fern

Bird's nest fern (Asplenium nidus) — a tropical fern that grows on trees in the wild and forms a shuttlecock-shaped rosette of glossy, bright green, undivided fronds with a dark midrib and wavy edges. Indoors it slowly reaches 1–1.5 m; it has no flowers. Bird's nest fern needs partial shade and 16–30 °C. Water it about every 7 days while it grows and about every 12 days in the winter rest.

Watering and repotting bird's nest fern through the year

It lives indoors all year, so it has no sowing or planting dates: it grows from March to September and rests from October to February (the other way round in the southern hemisphere).

Repot it about every 36 months.

When to plant bird's nest fern?

Plant or repot bird's nest fern in spring, as it starts into growth; early to midsummer also works. It is a houseplant, so it has no outdoor planting date and no frost decides it: just avoid autumn and winter, when growth slows and fresh compost stays wet too long. After that, move it to a slightly larger pot about every three years, or sooner once roots circle the pot or grow through the drainage holes.

Growing notes

Light

Bright, indirect light, such as an east-, west- or north-facing window. Too much direct sun turns the fronds yellow or stops growth; in a south-facing room keep it behind a sheer curtain.

Soil

A rich, free-draining, slightly acidic mix with plenty of organic matter, for example peat-free houseplant or ericaceous compost with some grit. Use a pot only slightly larger than the root ball; overpotting leads to root rot.

Care

Water when the top 2–3 cm of compost feel dry, pouring around the edge of the pot rather than into the centre of the rosette, and never leave it standing in water. Do not let it dry out completely, but too much water is the more common killer, so check the compost before watering if fronds turn brown. Use rainwater or room-temperature water where possible. Keep it at 16–30 °C, away from radiators, heat vents and cold draughts, and raise humidity with a pebble tray or humidifier, especially in winter; a bright bathroom suits it well. Feed monthly from late spring to late summer with houseplant fertiliser at half strength. It grows slowly and needs repotting only every few years, in spring. Remove only dead or damaged fronds and handle the brittle fronds gently. Watch for scale insects and mealybugs; insecticide sprays damage ferns, so wipe pests off by hand.
