Rosemummy touched on this above.......and I would stress the importance of using Mycorrhizal Fungi, particularly if planting where roses have grown previously.
There have been some change in thinking re planting depths since I started out, but I still plant mine the old way i.e. with the graft union just above the surface of the soil. Modern thinking dictates the graft union being "at soil level (not below as this is reported to increase the risk of rose dieback)".......as per the RHS.
