- Get neighbors or other like-minded people together. Find a good spot of land, and apply for a variance from your city... if the group buys it, you want to use that space for keeping chickens and bees, and run a community garden and/or plant an orchard or berry brambles. Combine your voice and negotiating power, pool finances and distribute responsibilities to ensure long-term success for providing healthy food for your family.
- Have room for only a couple of trees? Replace non-food-producing trees with grafted fruit and/or nut trees. There's a "fruit cocktail" tree that grows nectarines, peaches, plums, and apricots. There's also a 5-in-one apple tree and a 5-in-one pear tree. These are generally dwarf trees so they don't take up a lot of space. There are also dwarf nut trees, like filberts and almonds. You could conceivably provide a lot of fruit and nuts for your family on the space of a normal-sized driveway. Starks Bros even has a colonnade group of fruiting trees that look like sticks with fruit growing on them... includes apples/crabapples and something called a rocket peach.
- Vines grow upwards: try grapes to provide fresh table fruit, juice and wine to bottle, and vinegar for cooking.
These are just a few suggestions. What do YOU think?
