From Ground: Water the bitterroot to dampen the soil, making it easier to lift out the plant. Make sure to dig a wide enough trench around the plant with your spade or shovel, taking care to avoid damaging the roots. Use the tool to carefully lift the plant and its surrounding soil.
From Pot: Water the bitterroot before starting the process. Gently tilt the pot on its side and lightly tap the edges. The plant and the soil should slide out together. Handle with care to avoid damaging the root system.
From Seedling Tray: Water the soil well before removing the bitterroot. Carefully hold the seedling by its leaves to avoid damaging the stem or roots, and lift it from the tray using a garden trowel. Handle with extreme caution to avoid damaging the young plant.
