From Ground: First, water the chinese birch 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 chinese birch plant thoroughly. Then, gently tip the pot and slide the plant out, supporting the root ball with your hands. If the plant is root-bound, you might need to carefully loosen the roots by hand or with a tool.
From Seedling Tray: Water the chinese birch seedlings lightly. Use a small tool or your fingers to gently lift each seedling out of the tray, ensuring you keep as much of the root system intact as possible.
