Care
Exposure
Place Rytidosperma caespitosum in full sun or partial shade for optimal growth. It tolerates wind-exposed areas well and develops better with generous light. Avoid overly shaded spots that would slow its vigor.
Watering
Once established, this grass is very drought-tolerant and needs little regular watering. Water moderately during the first season to encourage root development, then reduce applications. During prolonged dry spells, occasional watering is sufficient.
Soil and drainage
Prepare well-draining soil, poor to average in nutrients, without excess fertility. This species tolerates rocky or sandy soils typical of its native habitat. Improve drainage with sand or gravel if your soil is heavy.
Pruning and maintenance
Prune lightly in spring to remove dead or damaged foliage. Avoid severe cutting: this grass prefers to keep its natural, tufted form. A fine-tooth comb allows you to remove debris without stress.
Fertilization
No fertilizer is necessary. This grass adapts to poor soils and develops naturally without regular feeding. Excess nitrogen can actually harm its structure and hardiness.
Health and prevention
Rytidosperma caespitosum is generally robust and rarely susceptible to disease. Ensure good drainage to prevent root rot. Adequate spacing between tufts promotes air circulation and prevents fungal problems.
Did you know?
Rytidosperma caespitosum, often called 'Wallaby Grass,' was once the basis of natural Australian pastures. It owes its common name to the fact that wallabies (small kangaroos) once grazed on these grasses in the savannas and temperate grasslands of South and South-East Australia. Today, it is being rediscovered for Mediterranean or dry-style gardens, a symbol of resilient flora adapted to water scarcity.
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.
