From Ground: Start by watering the glaucous sedge to dampen the soil. This makes it easier to remove the entire root ball. Now, dig a wide trench around the plant using the shovel or spade, ensuring to encompass the entire root ball. Once you've dug around the plant, work the spade underneath the root ball. Try to keep the root ball intact as you carefully lift the glaucous sedge out of its original location.
From Pot: Water the glaucous sedge plant then gently tip the pot on its side and coax the plant out. It should slide out with the root ball and soil. If the plant resists, you can run a knife around the inside of the pot to loosen it.
From Seedling Tray: First, water your young glaucous sedge plant. Gently hold the plant at its base and apply pressure to the underside of the pot with your other hand until the plant and its root ball come out.
