How to keep Carex Supina.
Light
Weak arctic sedge is a sun-loving, perennial herbaceous plant that comes from open habitats and commonly thrives in meadows and grasslands. It prefers full sun but can also tolerate partial sun.
Fertilizer
Weak arctic sedge needs extra nutrients to encourage healthy new growth. In spring, spreading some compost around the plant's base can effectively supply the nutrition it requires. Fertilizing supports robust growth and helps the plant resist diseases and pests.
Pruning
To promote healthy growth, it's important to prune weak arctic sedge in early spring before new shoots appear. Trim away any dead foliage and remove old stems to prevent overcrowding, reduce the risk of disease, and encourage vigorous growth. This will help maintain a compact and tidy appearance for the plant.
