From Ground: Start by watering the swamp Rose plant thoroughly to soften the soil. Then, using a shovel or spade, dig a generous trench around the plant, ensuring that the root ball is not damaged. The trench should be deep enough to incorporate most, if not all, of the roots. Carefully lift the swamp Rose from the ground, making sure you incorporate as much of the roots as possible to minimise stress on the plant.
From Pot: If your swamp Rose is in a pot, watering it well before starting helps to ease the removal. Turn the pot sideways, hold the swamp Rose close to the base and gently pull or tap on the pot until the plant comes loose. Avoid pulling by the stems or leaves as this can damage the plant.
From Seedling Tray: If the swamp Rose is sprouting from a seedling tray, handle it very delicately to avoid damaging the young roots or shoots. Loosen the soil and carefully lift the seedling by the leaves and not the stem. You might use a small tool or your fingers to help dislodge the seedling while preventing damage.
