From Ground: Begin by watering the southern dewberry plant to dampen the soil around its roots. Use a shovel or spade to dig a wide, shallow trench around the plant, taking care not to damage the roots. Work the spade under the root ball and gently lift the plant from its original location. Place it carefully in a bucket to prevent the roots from drying.
From Pot: First, water the plant. Turn the pot sideways, hold gently the southern dewberry plant's base and try to slide it out. You might need to tap the pot's bottom to facilitate this process. If the plant is pot-bound (roots filling the pot), you might need to break the pot.
From Seedling Tray: Carefully lift the southern dewberry plant with a dibber or a small trowel, supporting the root ball. Do not hold the seedling by the stem as this can cause damage.
