our gardens can feed us -- practice growing calorie crops
Even if some of us are just beginning or have a small space, it takes time to learn what grows and how. I am still learning, and I will have some experiments this year, but the focus is to see about growing "easy" to grow calories, how much for the space and effort.
One place to start learning about gardening is the Biointensive self-learning free materials, here : http://www.growbiointensive.org/Self_Teaching.html with a short, free handbook and a short video course series. The main book, of course, for this method is "How to Grow More vegetables..." and is in many languages. The Diet/21 bed booklets are interesting as well for ideas on one way to learn to grow your own complete diet, it is not the only crops to use, but is an experiment into one of the ways it can be done, with the least square footage. This has now been replicated for other areas and cultures with different crops.
Booklet 14, complete 21 bed model is the original one that runs the numbers on one way to grow a complete diet on around 2000 sq ft of space. Companions to that are the short 1 bed teaching/learning beds. SO, try it out with just one bed to learn how to grow these types of crops and to rotate (booklet 26), there is also the 3 bed model for Kenyan diet ( booklet 25) and one basic mexican diet ( booklet 15). Looks like there is an update to the 21 bed model, using less stringent and possibly more easily doable space, booklet 36, including a 3 bed model to learn on and plans for at scale. http://www.growbiointensive.org/ePubs/index.html
So, they use the term calorie crops for what we need the most of to feed ourselves, things like potatoes, sweet potatoes, winter squash..... And I will be practicing some of these this season.
First, and main crop for me is the potatoes, more than I have ever tried for. I have 3 beds planted out to potatoes. These are the first 2 early planted beds of Yokun gem, Yukon gold and red norland, they should be out and done before end of june, and I plan to replant to early corn.
