Growing enough food to survive solely off the land is a big feat. It’s one I have never tried to accomplish! First, it requires an immense amount of land or growing space that isn’t easily accessible to everyone. It also requires an immense time commitment to keep your garden in good shape. Rather than try to survive off of only your food, grow enough to replace some of your groceries. What you can’t grow or don’t have enough of, purchase from CSA subscriptions, farmer’s markets, or local growers.
