Rimmer, I am in the North Carolina mountains, zone 6a - 7b depending what elevation you are, I am in a cold pocket, about 2 weeks behind other local gardens. I planted the them only with the small amount of potting soil that was in the 2-3" pot they were in. Have never bare rooted any when I planted them. Plant that was given to me was dug up where some seed had been planted by a mouse or ants, so was in native soil at a friend house that does not have this problem. As far as rust they do not look like they have rust but I don't know what rust looks like on them, I have never seen it on jack's. I am a retired perennial propagator so have grown a lot of plants in various garden and have not had this kind of problem.
