Water: Sleepy grass flourishes with moderate hydration, requiring weekly watering to thrive. This herbaceous perennial prefers outdoor environments, benefiting from natural rainfall and seasonal growth cycles, aligning with its historical adaptation to prairie moisture conditions.

Fertilize: To care for sleepy grass, apply a thin layer of mulch or compost in spring for gradual nutrient release, ensuring no direct contact with the stem to prevent rot. Avoid over-fertilization and use organic materials to enhance growth and support the ecosystem. Minimal intervention is needed for optimal health.

Regular pruning enhances density and vitality, supporting its natural growth cycle for vibrant beauty throughout the season.

Propagation: Sleepy grass is a native perennial grass that forms tufted clumps. Propagate by dividing mature clumps during dormancy, replanting at the same depth and ensuring adequate water for establishment.
