From Ground: Begin by watering the common nipplewort plant to dampen the ground, this makes it easier to remove the plant. Dig a generous trench around the plant with your spade or shovel, ensuring you're not too close to the plant to avoid damaging the roots. Gently work your way under the common nipplewort's root ball with your spade, taking care not to harm the roots. Lift the plant slowly from its location.
From Pot: Water the potted common nipplewort plant first as it helps to hold the soil together. Tilt the pot sideways, supporting the topsoil around the plant with your other hand. Give the base a gentle tap, if the plant doesn't slide out easily, run a trowel around the inner rim of the pot to loosen it, and then repeat the gentle tap.
From Seedling Tray: Water the common nipplewort seedlings to bind the soil together. With your fingers, apply gentle upward pressure at the base of each cell to pop the seedlings out, keeping the root ball intact.
