I found this interesting piece on MotherEarthNews
and I quote :
Most homesteaders seek what is referred to as “self sufficiency.” I have blogged on this topic in the past, but there are so many facets to the subject that writing could be extensive and exhaustive. Being able to grow your own vegetables is personally rewarding and provides a source of food that you know hasn’t been washed in something or treated before you get it. Gardening is the most often used term when talking about food self sufficiency.
Our personal garden is still producing well into the fall season. It is a small garden, but then it only has to provide for two people. Insects are not a problem in the mountains but rodents are a major problem, which is why we grow most of our vegetables in an aboveground garden box totally encased in hardware cloth
