Let me see if I can follow the line of logic here. Planting them in the
late summer/fall causes roots to grow. Established roots in a freeze
thaw environment cause the rzs to rachet up and heave, tearing the roots
and rendering them useless. Rzs left on top of the ground did just fine
So why not just wait for the spring thaw to plant them and avoid all
I like the other process. Let them freeze, mulch them to keep them
frozen (no heaving). Uncover them when spring thaw arrives.
