What is the best way to transplant heirloom roses?

These roses are over 40 years old and the roots are very large. When is the best time of the year?

What is the best way to transplant heirloom roses?
Best time of year first.....Early spring or fall with at least 8 weeks of weather before freeze so roots have enough time to get established before freeze.


Large roots......do the best you can at recovering the most roots. Be sure to prune any off that are dead or broken before planting and be sure to WATER WELL. Dont forget to water often during for the first few weeks. a Good rose fertilizer (avail at local "mart" store) is a good idea but NEVER fertilize roses after August.
Reply:What zone are you in? If your up north do it now that way the roots can get established before it starts to frost. But I would wait to prune until spring. Also keep as much of the dirt that their already in as possible.
