From Ground: Start by watering the rose blackberry plant to soften the soil, making it easier to work with. Use a shovel or spade to dig a generous circle around the plant, several inches away from the base to avoid damaging the roots. Gently pry under the root ball and lift the plant out of the ground with its root system intact.
From Pot: If rose blackberry is in a pot, water it well prior to the start of the transplantation. Turn the pot to the side and gently tap or press the sides to loosen the root ball. Slide the plant out of the pot, being careful to support the plant and its roots during the process.
From Seedling Tray: With rose blackberry in a seedling tray, first make sure the soil is moist. Use a trowel or your fingers to carefully lift the plant from its compartment, taking care not to damage the delicate roots and shoots. It's essential to handle the seedling by the root ball rather than the stems or leaves.
