Put on gloves. Excavate the grass and topsoil around the base of the large sedge using a pickax and shovel. Keep excavating until the sedge roots become visible.
Wrap a tow strap tightly around the base of the large sedge, cinching it as tightly as possible with the claps.
Attach the other end of the tow strap to the tow-hook on a truck. Slowly begin to drive away, making the tow strap taut.
Drive the truck slowly farther away once the tow strap is taut, pulling the large sedge and its root system out of the ground.
Backfill the hole left in the ground by the large sedge with a shovel. Fill the hole all the way up to ground level with topsoil thereafter.
Spread grass seed over the topsoil or lay down sod to cover the excavated area and regrow grass to blend with the rest of the lawn on your property.
