Maintain consistently moist soil, mimicking its natural wetland habitat. Sagittaria natans thrives in shallow standing water or waterlogged soil.

Avoid allowing the substrate to dry out completely, as this can stress the plant. Regular watering is crucial for healthy growth, especially during warmer periods.

Pruning is minimal for Sagittaria natans. Remove any yellowed or dead leaves as they appear to maintain plant health and aesthetics.

Trim back overly crowded foliage if necessary to improve air circulation, but avoid excessive cutting as it prefers a naturalistic growth habit.

Sagittaria natans readily propagates through runners and the division of tubers. Runners will form plantlets that can be separated and replanted. Mature plants can be divided during repotting.

Seeds can also be collected and sown in moist substrate.

Repotting is typically done every 1-2 years or when the plant becomes pot-bound, usually in spring. Use a heavy, shallow aquatic pot to prevent tipping.

Ensure the substrate is a heavy loam or aquatic planting mix, and plant tubers just below the surface.
