If you do not have enough space in your garden, grains are not conducive for your farm. A few pots and a few patches cannot be turned into a grain farm. If you have abundant space, then you can grow grains for baking purpose or for feeding the livestock. Remember that a lot of pests and bird feed on the grains. You may need a scarecrow. One can grow wheat, oats, barley, corn, flax and rye, to start with. If you want to use them for baking, you should cure, thresh and grind them. Growing your own grains will give you a sense of fulfillment which is rare, to get, these days, owing to our stressful lifestyle. It will allow us to be self sustainable and allow us to grow our own food.
