Planting threeway sedge (Dulichium arundinaceum) is a relatively simple process that can be performed in both a pond or a wetland habitat. Follow these steps to ensure successful planting and cultivation of threeway sedge:

  1. Choose a suitable location that receives full to partial sun. Threeway sedge thrives in wet, boggy conditions, so ensure the planting area has good drainage.
