Care

Watering

Once well established, this Australian grass tolerates drought well and requires minimal watering. During planting or in hot spells, water regularly for the first two months. Afterward, watering is only needed to compensate for lack of rain in summer.

Exposure

Place Rytidosperma setaceum in full sun to achieve the best foliage and abundant flowering. It can tolerate light dappled shade, but the plant will be less dense and less ornamental. Avoid overly shaded and humid areas.

Pruning and cleanup

Clean out dead or damaged parts in late winter, before new growth resumes. Cut dried leaves at the base without severely cutting back the entire clump. A light combing in spring is enough to maintain its open form.

Soil

Choose well-drained soil, even poor or stony, as this grass dreads waterlogging. It adapts to dry soils and needs very few nutrients. Avoid compacted or heavy clay soils without proper aeration.

Fertilizer

No fertilizer is needed once the plant is established. A naturally balanced and well-drained soil is sufficient for its development. Excess nutrients may encourage overly vigorous growth and reduce its graceful appearance.

Diseases and pests

Very hardy and little susceptible to pests, this grass mainly fears excess moisture which can lead to root rot. In well-drained soil and sunny exposure, it remains healthy and vigorous. Specific treatments are generally not necessary.

Did you know?

Rytidosperma setaceum is an Australian grass prized by modern landscapers for its fine, silky texture that shimmers in the setting sun. Its scientific name 'setaceum' literally means 'resembling silk,' referring to the characteristic delicacy of its leaves, making it an essential element in contemporary Mediterranean and dry gardens.

Where to buy it

Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
