Yes, I have searched the site for overwintering articles ... they are all fantastic. I thought I'd ask some specific information on my environment though.
I live in Michigan, in an Apartment. The winters get really cold here ... I have 2 elms that I need to overwinter on my balcony (rather small, 9 feet wide by 5 feet deep).
Should I put them in some sort of insulated box? Do they need to see the sun? How often do they need water?
Thanks
Jason
