The problem of replanting a rose where one has grown previously is now really no longer the problem it once was. Science and plant breeder discovered the lack of plant aiding fungus and came up with Mycorrhizal Fungi.
As allium says replenish the bed and give the new rose roots a generous sprinkling of the fungus spores, water well and let the new plant get on with it.
Science knows relatively little of what goes on beneath our feet, so gardeners will benefit from the growing body of research now going on.
The fungi is readily available, just buy the type recommended for roses
