Hair-grass, a genus of meadow grasses, thrives in sunny to partially shaded environment. They prefer moderate watering and temperature conditions, around 15-25°C, and well-drained soil. They are resilient but are often plagued by fungal diseases and pests like aphids. Mites are also a common issue. Seasonally, they relish summer's warmth, require regular watering in the hotter months, and less in winter. During autumn, removing dried leaves helps prevent fungus. Pruning in spring promotes fresh growth.
