With a winter protection, your tree should be fine planted in the ground. Plant it id you can.

If you're leaving it in a container, that's a bit small for a 6' tall tree. I would be more inclined to pot it up into a 15 gal container, but I'll defer to our container citrus experts.

its probably close to being root bound if it isn't already.

what do you plan for the meyer? in ground or in pot? do you want it to get big?
