How to grow weeping grass
Overview
Weeping grass (Microlaena stipoides) is a fine-textured native grass grown for its graceful, arching foliage and soft movement in the garden. It provides a dependable, low-maintenance groundcover that adds rhythm and texture to planting beds, especially in shaded or woodland settings.

Soil Preparation
Weeping grass prefers slightly acidic to neutral soil (pH 5.5–7.0) with good drainage. Improve heavy clay with coarse sand or organic matter. Avoid waterlogged sites; if soil is poor, top-dress with compost before planting.
Growing Guide
Plant weeping grass in part shade to dappled light, avoiding harsh afternoon sun. It prefers well-drained loam or sandy soil with steady moisture; water deeply once a week during dry spells. Space clumps 30–40 cm apart for a dense groundcover, or 50–60 cm for a more open meadow effect. Sow seed directly on the surface in autumn or spring, lightly raking in, and keep moist until germination in 2–3 weeks.
Sowing
Sow seed directly on the surface in autumn or spring, lightly raking in. Keep moist until germination in 2–3 weeks. Space 30–40 cm apart for groundcover. Direct sowing is preferred; transplanting is possible but less reliable.
Care
Feed with a low-nitrogen native fertiliser in early spring. Trim back old foliage to 5–10 cm in late winter to encourage fresh growth. Divide clumps every 3–4 years to maintain vigour and prevent centre dieback.
Companion Planting
Weeping grass pairs well with understorey plants like Dianella, Lomandra, and native ferns. Avoid planting with aggressive, fast-spreading grasses such as kikuyu or buffalo, which can outcompete it.
Common Pests & Risks
Weeping grass is generally pest-free, but can occasionally suffer from grasshoppers or caterpillars in late summer. Treat with a low-impact insecticide or encourage natural predators like birds and wasps. Fungal issues are rare if drainage is adequate.
Troubleshooting
Yellowing foliage: overwatering or poor drainage – reduce water and improve soil. Brown leaf tips: dry air or underwatering – increase humidity or water more frequently. Sparse growth: too much shade – move to brighter spot. Centre dieback: clump too old – divide every 3–4 years. Seedling failure: dry soil during germination – keep consistently moist.
