About 3 years ago we moved a Mermaid from my garden to my daughter's. The Mermaid was about 7 years old and well established. We cut it back to about 2 feet, then dug it out leaving as much of the rootball as possible intact. We wrapped it in a plastic tarpaulin, keeping it damp and took it to my daughter's garden. Due to some awful weather she didn't get it planted for about a week, but she kept it well wrapped and damp but not sodden. She dug out a hole a bit bigger than the rootball and added some well-rotted stable manure and dug it in, then planted the rose. Three years on it covers the walls and roof of the garages at the end of their garden, acting as a wonderfully thorny deterrent to anyone thinking about trying to get into their garden from the path behind.
Ramblers are usually wonderfully resilient.
