How to Care for Kangaroo Paw Fern

Kangaroo Paw Fern (Zealandia pustulata, formerly Microsorum pustulatum) is an attractive, easygoing fern with leathery, glossy green fronds that develop lobed, paw-like divisions as they mature. It grows from a creeping rhizome and is more forgiving of typical indoor conditions than many delicate ferns.

Light

Give Kangaroo Paw Fern medium to bright indirect light. It appreciates a bright spot out of direct sun, such as near an east-facing window or set back from a brighter one. It tolerates medium light but grows more slowly there. Avoid harsh direct sun, which scorches and bleaches the glossy fronds.

Water

Keep the soil lightly and evenly moist, never soggy and never bone dry. Water when the top of the soil begins to feel dry, giving a thorough drink and letting excess drain away. This fern is somewhat more drought forgiving than fussier ferns thanks to its thick fronds and rhizome, but prolonged dryness causes crisping, while constant sogginess rots the rhizome. Use room-temperature water.

Soil & Potting

Use a light, airy, well-draining mix rich in organic matter; a peat or coir based houseplant mix with added perlite, orchid bark, and a little sphagnum works well. The creeping rhizome grows along the surface, so plant shallowly and do not bury it. A pot with drainage holes is essential. A wide, shallow container suits its spreading habit.

Humidity & Temperature

Like most ferns it enjoys moderate to high humidity and appreciates a boost in dry indoor air; group it with other plants, use a pebble tray, or run a humidifier. It prefers warm, stable room temperatures and dislikes cold drafts and sudden chills. Keep it away from heating vents and cold windows, both of which dry and stress the fronds.

Feeding

Feed lightly during the growing season, spring through summer, with a dilute, balanced liquid fertilizer roughly monthly. Ferns are sensitive to fertilizer salts, so keep doses weak and flush the soil occasionally. Stop or greatly reduce feeding in autumn and winter when growth slows.

Propagation

Propagate by division of the creeping rhizome. In spring, lift the plant and cut the rhizome into sections, each bearing several fronds and a portion of roots, then pot them up in fresh moist mix. Keep divisions warm and humid until they establish. Sections of rhizome laid on moist mix will also root from the nodes.

Repotting / Pruning

Repot every couple of years or when the rhizome overflows the pot, choosing a wide, shallow container and keeping the rhizome sitting at the surface. Spring is the best time. Pruning is minimal: trim away any browned, damaged, or old fronds at the base with clean scissors to keep the plant tidy and encourage fresh growth.

Common Problems & Pests

Brown, crispy frond edges usually indicate low humidity or the soil drying out too far, while yellowing, mushy fronds point to overwatering and poor drainage. Scorched pale patches come from direct sun. Watch for scale, mealybugs, and spider mites, the last favored by dry air; raise humidity and wipe or treat pests promptly. Good drainage and steady moisture prevent most trouble.

Seasonal Care Tips

In spring and summer keep the soil evenly moist, feed lightly, and repot or divide as needed. In autumn and winter reduce watering slightly and pause feeding, but maintain humidity, as indoor heating dries the air and stresses the fronds. Keep the fern warm and away from cold drafts year round.
