They are cheap - just get the kind sold for feed. They will grow in cold wet weather. They will freeze to death about the time the ground freezes hard and will be effortless to dig in the next spring. Oats and other grains have a very fibrous root system that helps develop a crumbly texture in heavy soil. You can find oats for sale in the city in small quantities in places that sell food for rabbits, birds, pet rodents, etc. or in feed stores in rural areas. The current issue of Organic Gardening suggests sowing overwintering crops like spinach mixed with oats: the oats grow, freeze, die and protect the veggie plants, which get off to a fast start in the spring. This is a big win if you have heavy soil which can't be worked early when it is cold and wet. I'm going to try this method. It's amazing what will overwinter, even in southern Canada, given the chance. Last year I overwintered lettuce, spinach, chicory and onions with just a few inches of dead leaf mulch. I'm also going to plant oats in the garlic plot. Buckwheat is excellent in frost free weather, but is easily killed by frost. Use it as a cover/smother/soil-improver in late spring and summer. It is juicy and fairly easy to chop up and dig in with a hoe. You can do this as soon as it starts to set seed, then plant another crop of buckwheat if there is time, else get the oats off to an early start. I have only about 250 sq ft of intensive raised bed veggie garden, but I find it worth while to 'fill in the blanks' in the fall with oats. I have heavy soil and like Kay says: "ANYTHING to improve the organic matter!" Beverly Erlebacher Toronto, Ontario Canada AgCan Z6b USDA Z5
