Answer: Dormant, bare root plants must be kept cool (above freezing but below 45 degrees) until planting, otherwise they will try to grow too early. If they have started to grow, the best you can hope to do is pot them up. Use containers large enough to hold their roots without crowding and with drainage holes in the bottom. Use a good quality potting mix formulated for container plants. Plant them in the containers and keep the soil slightly moist, not sopping wet and not dried out. Put them outside when the temperatures are above freezing, bring them into a cool place such as an unheated garage whenever it is below 32 degrees. Hopefully they will continue to grow and releaf in a few weeks time. Once the weather has settled and freezing temperatures are over, and once they have rooted well in the containers and are growing healthily, plant them in the garden. In the meantime, do not let them sit in water for too long. After eight hours or overnight in the water, take them out and wrap in damp newspaper, then place the roots only in a plastic bag until you can pot them up. (Leave the canes in the air. Do not let the roots dry out now that you have wet them.) Try to pot them up right away. Good luck with your roses!
