Soil Type

Water: Originating from areas with varied moisture, blue grass shows moderate drought tolerance. It thrives with a watering schedule of twice weekly to maintain soil moisture. As an outdoor grass, blue grass benefits from natural rainfall, requiring less supplemental irrigation during the growing season when precipitation is sufficient.

Fertilize: Fertilize blue grass with mulch or compost at the beginning of the growing season, then lightly every 3 months. Use a thin layer to avoid over-saturation. Withhold fertilizer during winter dormancy, ensuring gentle integration into the soil for root protection. These practices support sustainable cultivation.

Pruning: Pruning blue grass in early spring before new growth promotes health and shape. Remove dead stems and thin dense areas for better air circulation, reducing disease risks. This practice encourages fresh growth and enhances overall vigor, resulting in a lush appearance throughout the year.

Propagation: A warm-season perennial cultivar, blue grass is resilient and suitable for ground coverage. Propagate by division in spring or early summer using healthy clumps with multiple shoots. Post-planting moisture is crucial for establishment and growth.
