Water: Swollen duckweed thrives in still or slow-moving freshwater, requiring weekly watering to mimic its natural habitat. It flourishes outdoors, spreading across the water's surface and benefiting from full sunlight, which enhances growth and contributes to ecosystem oxygenation.

Fertilize: Fertilize swollen duckweed with balanced nutrition fertilizers bimonthly during active growth to promote lush growth. Apply diluted liquid fertilizers evenly to prevent algae. Adjust for seasonal changes, reducing in cooler months. Monitor water quality and follow package instructions to avoid nutrient burn.

Pruning: Swollen duckweed flourishes in stagnant or slow-moving freshwater and is characterized by dense green clusters. Pruning in early spring encourages growth and manages space, promoting water quality and ecosystem balance. Adhering to ecological guidelines is vital, as swollen duckweed can significantly affect aquatic environments.

Propagation: Swollen duckweed is simple floating aquatic plants that propagate primarily through vegetative fragmentation. Optimal growth requires quality water, sufficient nutrients, and bright, diffused light. Maintaining stability prevents overcrowding, promoting healthy expansion and growth.
