Annette Shrader visits with an experienced gardener who adheres to the methods of permaculture. All of the plants in his vast backyard are part of a food forest, and each plant contributes in some way to the good of the whole. Food guilds, trap plants, green manure, and chop+drop plants are discussed, along with how they make edible plants thrive.
More folks are growing their own food these days, so perhaps a nut crop could fit into the home landscape. Tammy Algood goes to Bethpage TN to learn about seed germination, what's needed for good pollination, and expectations of yield over the course of the tree's life (which can be 150 years).
