From Ground: First, water the cattail sedge plant to dampen the soil. Then, dig a wide trench around the plant using a shovel or spade, ensuring the plant's root ball remains intact. Carefully work the spade under the root ball to lift the plant from its original location.
From Pot: Water the cattail sedge plant to make the soil easier to work with. Gently turn the pot on its side and tap the bottom to loosen the plant. Carefully slide the plant out, supporting the root ball as you do so.
From Seedling Tray: Water the seedlings to make the soil easier to work with. Use a trowel to gently lift each seedling from the tray, taking care not to damage the roots.
