Care
Light exposure
Gaudinia fragilis prefers full sun to partial shade. It tolerates bright locations and thrives in airy spots. Avoid overly dark areas that would slow its development.
Soil
This grass adapts to most soils but prefers well-draining, light substrates. It tolerates poor and even rocky soils. Avoid excessive stagnant moisture that could promote root rot.
Watering
Water moderately during the active growth phase, without letting the soil dry out completely. Once established, Gaudinia fragilis tolerates drought well. Reduce watering in winter or after flowering.
Pruning and cleanup
Remove dry or damaged parts as needed. At the end of flowering, you can lightly cut back the clump to encourage a compact appearance. This fine grass requires only minimal maintenance.
Fertilizer
Gaudinia fragilis isn't a heavy feeder. A light application of balanced fertilizer in spring is sufficient. In poor soils, an annual mineral application can support growth, without excess.
Diseases and pests
This grass is generally robust and rarely subject to pests. Ensure good drainage to prevent fungal diseases. Problems remain rare if growing conditions are respected.
Did you know?
Gaudinia fragilis is a discreet yet characteristic grass of dry meadows and Mediterranean limestone hillsides, where it forms light, undulating carpets at the slightest breeze. Its Latin name 'fragilis' evokes its apparent fragility, but this pioneer plant is actually well-adapted to arid conditions and efficiently colonizes disturbed habitats, playing a major ecological role in stabilizing poor soils.
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.
