Ok...I have a side bar question. I have a White Pine and a few older Junipers that need to be dug up at my folks place. The junipers have been there a long time...but need to be dug up and moved to a better location. I was planning an in-the-ground bed in my yard with protection...but of course I would rather put them into the proper training grow boxes...I always seem to be able to recover sick plants better in grow boxes than the ground.
Anyway, the question is that I do not have a winter harbor anymore for larger trees...can you plant the whole grow box into the ground for winter? mulching...watering...caring for them as if they were in the ground of course. then, pull them up in the spring for additional work
I always wonder about better winter protection for the roots. I live in a south suburb of Chgo...Zone 5. It can get pretty brutal.
Any thoughts?
