Organic lawns are lawns that the grass grows because of a healthy soil base not because it has been treated with tons of chemicals. In organic lawns there are thousands upon thousands of workers making sure the soil nutrients are available. These workers a come in the form of beneficial microbes, fungi, earth worms and beneficial insects. So if you are growing your lawn organically you have a huge work force taking care of your soil and feeding your grass even while you sleep. Nature is totally amazing and works well when we work with it.
