Water: Asian watergrass thrives in tropical wetlands, requiring high humidity and consistent moisture. Weekly watering is essential to maintain hydration. Primarily an outdoor plant, asian watergrass flourishes with ample water during its active growing season for vigorous growth and resilience.

Fertilize: Fertilize asian watergrass with mulch or compost every two months to promote growth. Increase to monthly during active seasons. Avoid over-fertilization; use slow-release options. Adjust schedules for seasonal growth, applying near the root zone and monitoring plant response for optimal results.

Pruning: Asian watergrass is a semi-aquatic plant thriving in waterlogged conditions. Pruning in early spring helps maintain shape, prevents overcrowding, and enhances water circulation. Clean, sharp tools are essential for effective pruning, which improves both aesthetic appeal and overall vigor of asian watergrass.

Propagation: An aquatic perennial, asian watergrass thrives in wetlands and propagates by division. Separate root parts with attached stems, transplant into similar water conditions, and anchor to prevent drifting. Divisions quickly establish and can expand into lush aquatic cover.
