Maintain consistently moist soil for Chinese Arrowhead, especially during its active growing season. It thrives in boggy conditions and shallow water.

Avoid letting the soil dry out completely, as this can stress the plant and lead to browning leaves. Reduce watering slightly in cooler months.

Pruning Chinese Arrowhead mainly involves removing any yellowed, brown, or dead foliage. Cut stems back to the base of the plant. This tidies its appearance and encourages new, healthy growth.

Pinching back overly long stems can help maintain a more compact shape if desired.

Sagittaria trifolia is easily propagated through division of its tubers or stolons. In spring, gently separate the plant, ensuring each division has roots and at least one growing point.

Alternatively, it can spread readily from seeds, though division is more common for cultivated plants.

Repot Chinese Arrowhead when it becomes overcrowded or outgrows its current container, typically every 1-2 years. Use a heavy pot to prevent tipping. Fresh aquatic plant soil or a mix of loam and sand works well.

Repot in spring for optimal establishment.
