Potamogeton crispus is sometimes cultivated as a pond plant, and generally speaking makes a good garden plant. Since it starts to die back rather early, it is probably a good idea to cut it back in July after it has flowered. In common with other pondweeds of this group it roots poorly from stem cuttings and is best propagated by division of the rhizomes or from turions. As it has proved invasive in some areas, curly pondweed should not be grown outside its native range.
