Answer: In almost all cases, mail order nurseries ship plant material at a time which is appropriate for planting in your area. Therefore, I'd advise planting shortly after you receive them.
Plant according to instructions, or see our guide <a href="http://www.garden.org/howtos/scripts/howtos.taf?id=1288"target"new">"Planting a Bare-Root Rose"</a>. If a hard frost still is possible, cover the lower part of the main stem and canes with mulch to protect them from the cold. Once growth resumes in late May, brush the mulch away from the center of the plant.
