Thanks for all of your advice so far... just one more question..

What do I do to try and make sure the leaves stay on over winter? Water
regularly, add a growbag, or a little of both?

Thanks again!

Basically try and ensure well watered, and that the temp in your area
doesn't get too low, the last is something somewhat outside of your
control, so you will just have to hope for the best in that.
