Hi MN, I live in a cold climate, agreed not Minnesota, but it does get down to zero and below (F) now and then. You are correct in saying that trees can come out of dormancy earlier than the norm for the area. The question is why? Yes it will allow for a greater growing (length) season, but it is not easy to do. Different trees require different lengths of dormancy (I !think most like 8 -12 weeks). Also, different tree types require different minimum temps(usually all below 39F), that said..... It is not just a light issue for starting to bring your trees out of dormancy. The 'type' of light and the amount is also important. The temp is an issue and most importantly the humidity is an issue, plus with too much humidity mold is an issue. Most of our homes are way to dry, even with a humidifier to have some trees inside. I guess you could start them inside a few weeks early, but how many weeks is a good question. Remember, if you could do this...you could raise the tree inside full time. That of course is something we know is not possible!

I am interested in the groups feeling on this issue. At the moment I live in Zone 5b (ish) and will probable be moving to Vermont in the next 6-8 months. So, I will be going to a colder climate and probably will have to do somethings different...say a greenhouse!
