Water: Grassleaf arrowhead thrives in moist, high-humidity environments typical of wetlands and marshes. It requires weekly watering for optimal growth and adapts well to changing water levels. Growth peaks during rainy seasons, as this aquatic perennial flourishes outdoors with consistent water availability.

Fertilize: To ensure optimal health, grassleaf arrowhead benefits from balanced nutrition through monthly fertilization during growth seasons (spring and summer). Use a diluted liquid formula to prevent root burn. Reduce frequency in fall and winter, and always water afterward for better nutrient absorption.

Pruning: Grassleaf arrowhead has unique grass-like leaves and benefits from pruning in early to late spring. Regular removal of dead or damaged leaves promotes new growth, while thinning dense clumps improves air circulation. Pruning enhances aesthetics and supports vigorous development and flowering.

Propagation: Grassleaf arrowhead is a perennial aquatic plant ideal for wetland habitats. Propagate by division in late winter or early spring, ensuring each section has a bud or shoot. Replant immediately in moist soil, as consistent moisture is essential for successful establishment.
