From Ground: First, water the marsh ragwort 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 marsh ragwort plant adequately. Turn the pot sideways, hold the plant gently by the base, and tap the pot edge on a firm surface to help loosen the plant. Gradually pull the plant out while avoiding damage to the stem or roots.
From Seedling Tray: Water the seedlings well before transplanting. Use a spoon or a dibber to lift the seedling out of its cell, keeping as much soil around the root ball as possible. Handle the seedling by the leaves rather than the stem to minimize damage.
