Care
Exposure
Install catapode in full sun for optimal growth and intensely colored foliage. This grass tolerates wind-exposed situations and direct heat very well. It also tolerates partial shade, but strongly prefers intense light.
Soil and drainage
This festuca thrives in well-drained, rocky or gravelly soils with poor to moderately fertile content. Avoid overly wet or compacted soil: adding gravel or coarse sand improves drainage. It adapts to neutral to slightly alkaline pH.
Watering
Once established, Festuca lachenalii is very drought-resistant. Water regularly in the first year to encourage rooting. Afterward, limit watering: one to two summer waterings are sufficient except during prolonged drought.
Pruning and maintenance
Comb or lightly mow in late winter (February-March) to remove dead stems and rejuvenate the clump. You can also manually remove faded flower heads after flowering. Avoid severe pruning that could damage the plant.
Fertilization
No fertilizer is necessary; this grass adapts to poor soils. Excess nutrients cause excessive growth and weaken the plant. A light application of organic matter (compost) in spring is sufficient.
Health and pests
Festuca lachenalii is relatively insensitive to diseases and pests thanks to its hardiness. Overly wet soil can promote root rot: improve drainage. No routine pesticide treatment is required.
Did you know?
The name 'lachenalii' honors Werner de Lachenal, an 18th-century Swiss botanist. This small festuca was traditionally called 'catapode' in the mountains, from ancient Greek evoking its tightly clustered form. It naturally colonizes alpine scree and gravel, where it plays a major ecological role in soil stabilization.
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.
