Water: Water whorlgrass thrives in wetland habitats with consistently moist soil, requiring weekly watering to maintain its ideal moisture levels. It prefers high humidity and is intolerant to drought, flourishing in regions aligning water availability with its growth cycle.

Fertilize: Water whorlgrass thrives with biannual compost application, reflecting its riparian habitat's nutrient dynamics. Avoid over-fertilization to prevent aquatic runoff. Adjust feeding during active growth, especially in spring, and ensure even distribution to enhance vitality while monitoring plant response.

Pruning: Water whorlgrass is a perennial aquatic grass with slender, whorled foliage thriving in wet habitats. Prune in early spring using sharp shears to encourage healthy growth and prevent disease. Regular pruning enhances airflow and light, promoting vibrant plant health.

Propagation: Water whorlgrass is a perennial grass that thrives in moist conditions. Propagation can be done by dividing rhizomes during active growth, ensuring each section has roots and shoots. Plant divisions in wet soil or shallow water for optimal root establishment, handling them gently to minimize disturbance.
