From Ground: First, water the purple toadflax plant to dampen the soil. Then, using your gardening fork and spade, dig a wide trench around the plant, 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: For pot-planted purple toadflax, water it thoroughly a few hours before transplanting. Turn the pot sideways and gently tap it to remove the plant. Try to keep as much original soil around the roots as possible. Be careful not to damage the roots during this process.
From Seedling Tray: Moisten the seedling tray soil first. To remove the purple toadflax plant, press the base of the cell gently and lift it out. Carefully separate any tangled roots without breaking them.
