This past spring, I pot planted a nice Cascade and it grew and grew and I got 3oz from it dried, not bad for a first year. It has since died down. I was mowing the lawn the other weekend and decided I could move the post and try and store it. When I picked it up, it wouldn't move and not thinking, I yanked hard and heard a smap. To my surprise, the root had grown thru the hole in the bottom of the terracotta pot (a big one mind you) and I snapped it in two.
I put the pot back where it was and am not sure what to do. Did I kill it? should I assume that the root in the ground needs to be protected from winter and will sprout in the spring? Should I plant my potted cascade in the ground? Just not sure what to do and any help will be appreciated.
