Care

Light exposure

Plant Calamagrostis villosa in full sun for generous flowering and optimal form. This grass also tolerates partial shade, but its growth will be less vigorous. Avoid overly shaded areas that would reduce its airy silhouette.

Watering

Water regularly during the first year to encourage root establishment. Once established, this grass is moderately drought-tolerant but prefers fresh soil. During extended summer periods, water if the soil surface becomes dry.

Soil and planting

Prepare well-drained, fresh soil rich in organic matter. Avoid compacted or waterlogged soil that promotes root rot. Adding compost at planting improves establishment.

Pruning and cutting

Cut back the clumps in late winter (February-March) before growth resumes, cutting to about 10-15 cm from the ground. This rejuvenates the clump and removes dried portions. You can also leave the winter foliage in place for its aesthetic interest in autumn and winter.

Fertilizer

Apply balanced fertilizer in spring when vegetation resumes. A well-established grass in rich soil needs only moderate annual fertilization. Avoid excess that would promote loose foliage.

Diseases and pests

Calamagrostis villosa is generally hardy against common diseases. Root rot problems occur mainly with insufficient drainage. Check soil drainage and avoid excessive watering.

Did you know?

Calamagrostis villosa is prized in contemporary gardens for its light silvery plumes that ripple in the wind, creating permanent visual dynamics. Its supple panicles earned it the nickname 'swaying reed' in landscape horticulture. It's a mountain grass that evokes the grassy slopes of Central Europe.

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.
