Erika you are an angel for giving these away instead of destroying them. I moved many many roses in the heat of summer and they survived. I just used big trash bags with some water squirted into the bags. The secret is to not let the tiny roots dry out, and as others said, water them well before digging, and prune them back. I agree with Steve on letting your rose loving friends do the digging. My cynical self thinks people take better care of something if they work for it.
