The best time to move rosebushes is when they are dormant. Moving them any other time will typically cause severe die back in their growth as the root system will not be established enough to support the current growth. If they must be moved while actively growing, water them a day or two before the move with some water that has a product called Super Thrive in it. This will help them deal with the coming stresses and shock of the transplanting. Once moved to their new locations, water them with some water that has both Super Thrive and a Root Stimulator product in it. Water them with this mix the next 5 to 6 times they need watering, even with the rains they need these additives to help them get their root systems established and to deal with the stresses and shock of the move.
