Burying Phragmites

  • Effective burial requires about 70 cm (or 27 in) of soil over the Phragmites

  • Make sure the sediment is dry to prevent Phragmites re-sprouting

  • Nearby municipal dumps can also bury mounds under 70 cm without additional cost

Piling Phragmites After Cutting

  • Simply move piles to shore. When left high and dry, Phragmites won’t re-sprout. Bare rock or nearby shoreline are best. 
  • If mounds are large, use a barge to collect cut Phragmites and a backhoe to move them to a pile 
  • Any regrowth can be managed by hand pulling or backpack spraying
  • Piles also speed up decomposition; crushing stems with equipment will also help speed up decomposition
  • If you can’t move the cut material out of a wetland, moving Phragmites into a pile can create areas of open water
  • If a field is nearby, you can also leave these mounds and burn them during the prescribed fire’s season

  • Cutting down stems isn’t necessary for this method
