No More Tilling For Me

After tilling my garden a few times my clay soil was so bad last year that I hardly got any food from my garden. I was quite distressed to see that the soil was cracked and hard and I began to worry. Yes, I know it sounds strange to some of you but I would lay awake at night worrying about my soil and how I would produce food for my family. I decided that I would do as others have done, and I began to cover my soil with all the leaves from my yard. I made paths of mulch and covered the rest of the garden with straw. When I need to plant I push aside the straw and plant the plants that I want to, then I cover it back up with straw. No tilling doesn't mean no digging. I still have to dig deep holes for my tomatoes and other plants but I am not tilling the entire garden. I am already seeing the results. When I went to put in plants my soil is full of earthworms. Last year that wasn't the case. I know it will take a few years, but I can wait and in the meantime I add composted manure and humus to the areas that I am planting to help things along. Do you till? Maybe you should try a small speck of your garden without tilling and compare the results.
