From Ground: First, water the two-flowered iris plant to dampen the soil. Then, dig a wide trench around the plant with a shovel or spade, making sure to preserve a large root ball. Carefully slide the spade underneath the root ball to lift the two-flowered iris out of the ground.
From Pot: Begin by watering the two-flowered iris to make the soil moist and easier to work with. Tip the pot sideways and gently tap the bottom to loosen the plant. Gradually ease the two-flowered iris out while supporting the base of the stem.
From Seedling Tray: Moisten the soil before attempting to remove the two-flowered iris. Use a hand trowel or spoon to gently lift the entire root ball from the seedling tray, being extra careful not to disturb the roots.
