And it is nearly impossible to spread it evenly.
When it comes to overseeding existing turf, it will also be impossible to stir up the soil 1/4" deep as well... I would want seed to germinate in a space between 2 plants 2" wide...

When the grass is cut short those 2", or more, bare spots really show up all over the lawn and you just can culivate those spots to be 1/4" deep w/out harrassing the plants all around it... many times the seed is still visible, just sitting on the surface of that bare spot so the compost, even a little compost, makes the necessary contact for the seed to germinate while on the surface...

This is the very reason why having dead grass clippings sitting in these little bare spots is so important... the seed will never stay in place otherwise...
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...
