From Ground: Begin by watering the burford thoroughly to ease the removal process. Then, dig a generous perimeter around the plant, going beyond the spread of its branches, with your shovel or spade. Aim to preserve a large, intact root ball as you lever the plant gently out of the ground.
From Pot: Water burford adequately before starting. Tip the pot sideways and tap the bottom to loosen the soil and roots. If the plant doesn't slide out, run a spade around the inside edge of the pot. Then carefully pull the plant out by the base, avoiding damage to the stems and roots.
From Seedling Tray: Moisten the soil in the tray to make the roots less stressed during removal. Gently press the soil from the bottom of the tray to help push the burford out. Use a tool or your fingers to lift the plant, holding it by its root ball and not the foliage.
