From Ground: First, water the avens 'Fireball' 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 plant thoroughly to make the soil easier to work with. Gently press the sides of the pot to loosen the soil, then tip the pot and carefully slide the plant out, supporting the root ball with your hand.
From Seedling Tray: Water the seedlings to moisten the soil. Use a trowel or a flat object to gently lift the seedlings out, making sure to keep as much soil around the roots as possible.
