Yes, that's a hard one..Clay is not really good for growing much (well Roses like some clay). Depending on how large your area is and how much money you want to spend there are a couple of options. You need to a sand and humus mixture and mulch into your soil. You can also use peat moss but it will raise the acidity so test and then likely add agricultural lime to raise the PH. You should till this into the soil to a depth of 4 inches or more. At that point, depending on your budget, you'll need to re-sod or begin from seed. The grass that is on there now will be sacrificed into the till.
Good Luck RM
