 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

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.
