We have the problem here in Düsseldorf in our back yard that it gets very soggy after it rains. I recently told a friend about this and he said I should spread a thin layer of sand on the grass. This will create a layer to absorb or filter water to lower layers of earth and the grass will simply grow taller in order to accommodate the new layer. It makes sense given all of the water we get around here and what I know about filtration under the earth.
So, I tried it today. My neighbor saw me and asked what I was spreading on the grass. I told him it was sand. He said - yes you need to do that from time to time.
Amazing - I had never heard of such a thing in the US. And, here it is a normal solution to the problem of water drainage in lawns (or the lack of drainage). Another tip for life overseas or life in an unfamiliar environment - ask a friend or a neighbor if you are baffled by local conditions.
To think - I could have asked three years ago.
