Answer: If the soil is hard and compacted and the grass cannot root the best thing to do is cultivate that soil and add organic matter to loosen it and help it drain well. If it is a reasonably small area just dig it with a shovel, as deep as the shovel blade, break the soil up, add a good amount of compost or other organic matter and mix it into the soil. If it is a large area you may have to rent a rototiller. After amending the soil, level it and reseed. I think you will find a great difference with the lawn this season.
