Water: Bulbous bluegrass thrives in moderate moisture, requiring weekly watering to maintain health. It tolerates short dry spells and benefits from natural rainfall during its growing season, supporting lush foliage development in habitats like grasslands and open woodlands.

Fertilize: For bulbous bluegrass, apply balanced fertilizers every 4-6 weeks during growing season. Avoid over-fertilization to prevent harm. Adjust feeding based on seasonal growth, watering after fertilization to enhance nutrient absorption and prevent root burn.

Pruning: Bulbous bluegrass thrives with early spring pruning, cutting dead stems and excess foliage. This promotes robust growth, enhances air circulation, and reduces disease risk, leading to a healthier lawn appearance. Consult horticultural sources for detailed care guidelines.

Propagation: Bulbous bluegrass propagates effectively by dividing bulbils, which should be separated during dormancy with roots attached. Plant in loamy, well-draining soil, ensuring proper spacing. Maintain consistent moisture without waterlogging, as bulbous bluegrass thrives in moist but not overly wet conditions.
