When your order arrives remove the wrapping, soak the plants in water over night and then heel them in as deeply as possible and then water. As soon as there is a thaw get the roses into their chosen spot. Prune off any shot buds, plant deeply, water well and wait with happy anticipation for the first new shoots that signal spring is here. Yes - but you must change the soil. Roses will not thrive where another has been growing.
Fresh soil is essential.
A Give them time. A newly planted rose is working to re-establish its root system, some of which was removed when it was lifted for dispatch. While roses soon grow new roots, they do not send out vigorous long canes immediately. Some varieties are faster than others and some will grow only in a tiered kind of way - a bit at a time. As long as there is growth in the spring following planting the rose is going to gain strength and find the resources to send out climbing shoots.
