Season extenders...

I have been spending my free time reading about four season gardening. This is not something I had previously considered given that I live in zone 5a. After reading about people in Maine being able to garden throughout the year I decided to get educated on the topic. It would appear that with the right preparation I could grow greens and some root crops year round. That would save us a tremendous amount of money considering that we eat tons of salads. My next goal is to get a proper cold frame built for our climate and begin testing this type of gardening out. I have a small hoop house that I have used to get a jump start on my spring gardening but I now intend to refit it such that it can also be used in winter.
