I wonder about the effects of freezing and thawing and UV light and what toll they may take on the bags. I have a 4ft avocado tree growing in a 5 gal bag that I will bring in when the freeze begins. I have a fig tree in a 30 gal bag I've left outdoors for 3 years now and it is hanging in there, certainly not a show piece. It is a Smart pot.
