As I recommended that everyone should have their own survival garden for the best teacher is experience. We don’t know the details how Native Americans grew their gardens 1000 years ago under our vary feet, but the early explorers were eye witnesses to some of their techniques. Using this information, my first year I used charcoal and ash to sweeten the soil but I actually made the soil more acidic. The yield was a corn stock the size of a blade of grass. The second year I used fresh fish for the source of nitrogen and my corn stocks grew 3 large ears of corn. The third year I used mulch that was not aged so my yield was one small ear of corn but I have learned a great deal in my forth year.
