Hey guys!!! We live in Ottawa, Canada. Husband and I are in serious thoughts to start a new garden in our front yard. But as u guys must be aware, Canada have distinct seasons , winters are very cold with periods of snow and summers can be hot and dry. What kind of flora gardening might possibly work in these zones? What are the precautions to be taken care? Also about the energy efficient windows and doors for my garden exit, I have already spoke with my dealer, Landmark solutions and they have offered us a good discount, does these energy efficient technology really help to keep the windows and doors from warping?
