From Ground: Start the removal process by watering the area around the culver's root to moisten the soil, which will make digging easier and minimize root damage. With your shovel, dig a wide trench around the culver's root, taking care not to cut through the root system. Work your spade or shovel under the root ball and gently lift the root ball along with the plant.
From Pot: If the culver's root is in a pot, watering before you begin will make it easier to slide out from the pot. Tilt the pot sideways and gently coax the plant and its root ball out of the pot by tapping on the sides. Avoid yanking the plant out as it can damage the roots.
From Seedling Tray: Gently remove the culver's root seedling by pushing up from the bottom of the individual cell. Be sure to handle the seedling by its leaves to avoid damaging the stem. If the roots have grown through the bottom of the cell, carefully snip these off before transplanting.
