Uncle Dale teaches a course at the University of Maryland titled Farm Management & Sustainable Food Production. He stresses that everyone can be a farmer through backyard farming. One of his students took this to heart and developed an new innovative product.
It's called a Nourishmat and according to the University of Maryland's College of Agriculture & Natural Resources website it is a "6 feet by 4 feet polypropylene mat with pre-cut holes, labels and a grid telling would-be gardeners exactly what, where, and how far apart to plant. The UV treated polypropylene cuts down on weeds and is outfitted with a drip irrigation system that works by simply plugging in a hose."
