Bare Root Roses
When you first receive your rose delivery, unwrap them, and inspect for any damage. Then carefully place the root or roots in a cool place to stop growth but with some moisture such as a damp cloth, so that they don’t dry out
As long as there is good wrapping or packing around the roots you can keep them for some time, such as in an empty freezer which is switched off. Keep the top open a tad of the freezer and make sure they are kept moist.
However, if you need to store them for more than say twelve days then I suggest you take them outside and heel them in.
Using this method you can store the bare root for some time, firstly create a trench around twelve inches deep in reasonable soil not too boggy, then lay the roots on their side at a 45 degree angle, cover the root ball with soil and heel them in with your boot, leaving the head of the root exposed.
Be sure to check the trench regularly for moisture and when needed gently ease out each rose for replanting in final destination.
Obviously they should be moved prior to the generation of new root growth as this is easily damaged so a good planting plan should be adopted in order to make certain the roses are given the best chance to thrive.
