I tried square foot gardening for the first time last year and it was a huge success. I had more vegetables in two 4x4 gardens than I ever had when row gardening. I am putting in at least two more this year.
I have had an herb garden for several years in one of those big 4' patio pots and it works wonders!
I had been told about SFG for years and finally bought his updated book a few months ago. Living in the desert some of his ideas won't work but as I read his book I found I was already doing many of the things he teaches in his book. It is a good book and uses sound ideas. I don't use a grid system permanently in my garden. I lay it all out and plant but don't have his fancy white squares. . .
Also being in a desert, I don't have his individual raised beds. They would dry out WAY too fast. My whole garden spot is raised but I then plant in the native soil and lots of compost. I do have more weeds. . . but not too bad.
My dad gave me Mel's book years ago. But, I had already fallen in love with a Californian Chines guy's (Peter something) idea of long 4' wide beds. All of mine are 4' x 8' right now, but next year I'll make one 12' long. I prefer solid paths over Mel's way. In French the concept may be called "potager".
I have some seeds to trade via mail if anyone is interested. Passionflower grows wild here and, next year, I may be able to get more wild plum bush/tree seed from under a tree/bush at the road. My wild plum seed produced 4 ft. trees this year, about 6 of them. Also, have some veggie seeds I can trade. TommyToe, the prize-for-taste-winning, lg. cherry tomato is my newest.
Here is a photo of my back yard take in 1993. Notice the Blue Spruce and arborvitae in back of my family, the lawn and broken concrete patio and the old pear tree. This was the first stage of the redo. Compare it to last autumn's photo. Each plant has a story. We have had weddings, funerals, showers, family and neighbors gather for shared events. I mostly sit and remember, now. A nice way to live the last stage of my life.
