From Ground: Initially, water the wild sweetwilliam plant to moisten the soil which will make uprooting easier. Use a gardening fork to loosen the soil around the plant, causing minimal root damage. Then, use a shovel or spade to dig around the plant; ensure to keep a good distance to avoid cutting into the rootball. Gradually, work the spade under the rootball lifting wild sweetwilliam from its original location.
From Pot: If the wild sweetwilliam plant is in a pot, first water it well. Gently turn the pot sideways, hold the plant at its base and tug it out. If it resists, tap the sides or the bottom to loosen the rootball.
From Seedling Tray: If you're removing it from a seedling tray, use a trowel to carefully lift the wild sweetwilliam without causing damage to the young roots.
