I bought an olive tree(in a major supermarket!) this year. I supect it may have been grafted onto a dwarfing rootstock as its trunk is only 15" high which hasn't changed over the course of the summer although overall it has gained 2'6". Should this be brought in for the winter or would putting something like bubblewrap around it's pot be sufficient if I put it against a west facing wall?
