Narrow-leaf duckweed is a submerged aquatic plant ideal for ponds, aquariums, and water gardens, where it helps oxygenate the water and provides cover for fish and aquatic invertebrates. It prefers partial shade and still to slow-moving water, spreading naturally without any additional fertilization. Simply maintain clean, nutrient-rich water and thin the colony periodically to prevent overcrowding.
