I have never used compost on my lawn. It's a 3 year old lawn. We have
lot of clay in this area (zone 7b/8a). There's quite a bit of rocks
too thanks to the lousy builder.

Whenever we mow, we leave the grass clippings on the lawn. We want to
use compost also this year to see if it makes any difference to the
health of the lawn.

How much compost should I add to the lawn? How should I do it? When
should I do it? Any other info you can provide would be great.

Thanks

Leaving the grass clipping, or better yet using a mulching mower will
provide a continuous supply of compost as the clipping decompose. I
would apply the compost, then overseed. Not sure about your
particular climate (we have harsh summers), but I would apply the
compost in the fall after mowing the lawn short, about a 1/4 to 1/2"
layer. One drawback...I applied mushroom compost to my lawn and the
following year had a horrible time with weeds, even though the compost
was very hot and steamy. I use processed organic products on the lawn
instead.
