Growing Guide: Duck Potato
Growing Tips
Plant Duck Potato in full sun to part shade and provide consistently wet, rich, loamy soil. It grows especially well with the soil submerged beneath approximately 2–12 inches of water, making it ideal for ponds, marshes, rain gardens, and shallow aquatic environments. Plant tubers or divisions approximately 12–18 inches apart in spring or early summer to give plants room to spread. Remove dead foliage in late fall and monitor growth in smaller ponds, as Duck Potato can spread readily once established.
