    Again I agree, but it is a common solution in the minds of many an lco... The subject just came up again... :)

    Thanks for the link. I actually have a copy of that paper. It's good to review it occasionally.

    Not sure how thick the clay is but its defiantly deep. The owner says the landscaper applied 3 to 6 inches of top soil although I dug a couple of test holes and the clay started an inch below the surface.

    So my question, Is aeration with a topdress of compost going to help this lawn?

    Is the soil compacted? How deep are you aerating?

    If the clay is compacted aeration will not fix the drainage problem. If the clay is not compacted, and you are aerating to a well into the clay, then conditions will improve over time.

    You need to map the area for compaction before you can determine what is the appropriate course of action.

    .... and buy yourself a soil sampler.

    How do I tell if the clay is compacted? My aerator pulls plugs about 3" deep.

    If there is no place to 'punch thru' the clay then you are going to have to live on the hardpan... Like starting a lawn on the sidewalk... 3-6 inches of sandy loam, hope for worms and watch the irrigation...
