Care
Watering
Trichophorum caespitosum thrives in moist environments and isn't afraid of waterlogging. Keep the soil constantly moist, particularly during the growing season. In pots, water regularly without letting the substrate dry out completely.
Light exposure
This grass thrives in full sun to partial shade. It tolerates partially shaded locations in warm climates. Choose a bright spot for optimal growth.
Soil
A peaty, acidic to neutral, and very moist or even spongy soil is ideal. This species adapts well to nutrient-poor soils typical of peatlands. Ensure excellent drainage to prevent stagnation in pots.
Pruning and cleaning
Remove dead or damaged foliage in late winter or spring. Light pruning helps maintain a compact and attractive shape. This operation is not essential for the plant's vitality.
Fertilizer
This grass doesn't require significant fertilizing, as it adapts to poor soils. A light application of balanced fertilizer in spring can support growth, but avoid excess.
Diseases and pests
Very resistant, this species rarely suffers from pests or diseases under appropriate conditions. Excess stagnant moisture can promote root rot: ensure good substrate aeration and adequate drainage.
Did you know?
Trichophorum caespitosum is emblematic of northern peatlands where it forms dense, cushiony mats. Its dense tufted structure allows it to stabilize fragile wetland zones, playing a major ecological role in maintaining these threatened heritage ecosystems.
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.
