Hi BrooklynStart, thanks for your answer, looks like I did not explain myself clearly enough, the idea of the potting was to babysit it a little or give it a boost but never to leave it there permanently. I live in Montreal (zone 5a) and winter temps go below -9F quite often. No JM will survive that in a pot, even if it is big. What I meant is to pot it during the growing season and then back to the ground before the freeze.
