To start this is my first post sure could use some help. This is a new hobby that took me 69 years to find, I love these little trees. Well I bought a little elm from one of the internet stores and two hundred or so in bonsia tools I'm ready HA. One thing on my pea brain what do here in Louisville Ky. with my tree this winter. I was ready to purchase an hunt for more trees but worried about what to do this winter. I want to do all I can to insure the trees health an not hurt them. I have read keep in garage or build a cold frame but no details. Sure would apreciate a reply or pm. thanks in advance, Skip
