From Ground: Begin by watering the soil around the possumhaw to dampen it. Use a gardening spade to dig a wide trench around the plant, ensuring the plant's root ball retains its shape. Work the spade gently under the root ball to dislodge the plant from its initial place.
From Pot: Water the plant in the pot. Tilt the pot sideways, tap it lightly or insert a trowel along the inside edge to help loosen the soil. Pull out the plant taking care not to damage the roots. You may need to lay the pot sideways and slide out the plant gently.
From Seedling Tray: Water the seedling tray before removal. Use a trowel or spoon to carefully lift out the possumhaw, taking care to keep the root ball intact.
