From Ground: First, water the buerger holly plant to dampen the soil. Use a garden fork to gently loosen the soil around the plant's root ball. Carefully dig a wide berth around the plant with a shovel or spade, ensuring you're far enough out not to damage the root ball. Lever the spade under the root ball to lift the plant from the ground.
From Pot: Water the buerger holly plant to ensure the soil is moist, which will make removal easier. Turn the pot to its side and gently tap it to loosen the plant. Grasp the base of the plant and ease it out of the pot, taking care not to tug on it harshly.
From Seedling Tray: Water the starter tray well before beginning. Use a spoon or a small tool to carefully dig around the seedling's root mass. Gently lift it out, maintaining as much of the root ball and surrounding soil as possible.
