Gardening is fun and nutritious! Anyone can grow food, it's easy. People think I joke when I say: food is free. But you pay for land and plants and seeds and equipment and the time it takes to work it and you have to know how to process it or cook it but, but, but.. But nothing!
OK in this day and age - gardening does require a small investment but the rewards are bountiful! Get a little dirt and some seeds and grow yourself a little friend that is so gracious as to allow you to consume its fruit. It's awesome.
