In our community we have a farm that is a CSA. I volunteered on the farm one afternoon. I said to an environmental intern from the University of Vermont that the soil appeared to me to lack organic composition. I asked him how they successfully grow anything. His answer: “fertilizer”.
This CSA and many others participate in the local farmers’ markets. Many of us believe that if it is purchase at a farmers’ market it must be good. I would like to encourage you to start small with a Square Foot Garden and see where it takes you.
One more point. A Square Foot Garden can be an urban garden. The only space it takes is a patio, a driveway or even a front yard.
