I have a Crown of Thorns that I need to bring into the house for the winter. I live in the lower penninsula of Michigan. It is very cold and snowy pretty much from December thru March. I do not have a large enough window area to put this plant in for the winter months. My house is dark and dreary because of the lack of windows with sun coming thru. I was thinking about putting her in the mud room which gets diffused light thru the door and put a sun lamp on her during the day. Does any one have any ideas for me to get her thru the winter?
