How to keep Trichophorum Alpinum.
Light
Cotton deergrass is a sun-loving, perennial, herbaceous plant native to open habitats and commonly found in meadows and grasslands. It prefers full sun but can also tolerate partial sun conditions.
Fertilizer
Cotton deergrass benefits from extra nutrients to encourage healthy new growth. In spring, adding a layer of compost around the plant’s base can effectively supply the nutrition it requires. Fertilizing helps support vigorous growth and enables the plant to resist diseases and pests.
Pruning
Cotton deergrass features tufted stems and fluffy seed heads. For best results, prune the plant in early spring to remove dead stems and stimulate new growth, but avoid severe pruning. Regular trims help improve air circulation and increase the plant's vigor, ensuring that cotton deergrass stays healthy and visually attractive.
