From Ground: Begin by watering the creeping thistle plant thoroughly to soften the soil. Then, using a shovel or garden spade, dig a broad circle around the creeping thistle, keeping it far enough away to avoid damaging the root system. Carefully work the spade under the roots, lever up slowly and lift the plant.
From Pot: Ensure to water the creeping thistle well in advance. Turn the pot upside down while holding the plant's stem and give a sharp tap to the bottom. The creeping thistle should slide out with the soil and root-sphere intact.
From Seedling Tray: Transplant the creeping thistle when it has two leaves or more. Use a garden trowel to gently lift the plant, make sure to include as many roots and as much soil around the roots as possible.
