Hi all. I am a novice in Zone 5/6, near the meeting of NY, NJ, and Penn. I have kept Bonsai for several years indoors. This is my first wintering of hardy plants. I have an unheated garage which I have placed a shelf near the north facing window. The shelf has a large lip ( 3 inches) so as to allow for the trees and a liberal amount of peat moss around them for some insulation. In addition I have a home made heater of sorts to prevent super low temps from harming the trees. I have a 1/2 inch copper tube under the shelf. The tube is filled and there is an electric heat tape on the copper when the temps fall below 32 F, the heat tape will come on. Being it is below the shelf the heat will rise. It is my opinion it will give a slight heating affect to the shelf. I hope it will reduce the possibility of single digit temps without bringing the temps up to high. I will get back to you all as the winter progresses.
