I have these beautiful pink roses that I would love to have more of and I already know they are not on a root stock. They are starting to get older and the bush is huge so what I am trying to say is I want to propagate them because the bush is to big to move any where else and it can not stay were it is. So at the time being it will be OK for a year or two more but I would like to start some more early. I have heard that seeds are a bad idea though not impossible is this true?
