If you’ve had a successful garden before you know nothing compares to what you can grow yourself. Produce your vegetables without pesticides or inorganic fertilizers. Eating fresh, healthy, unprocessed food is the best way to survive. Non-hybrid and heirloom plant varieties will produce viable seeds that you can collect, store, and plant the next season which is what sustainability is all about. Whether you have acreage or a patio anyone can grow something to at least supplement their diet. Plant a wide variety and experiment with cultural practices to increase your knowledge and skill in home gardening.
