how to improve a yard's soil?
Our yard is just a mass of gritty red clay underneath the grass. The
contractors obviously bulldozed off all the topsoil and probably hauled
it away and sold it. Does anyone have any suggestions for improving
the soil over the longer term? Does leaving the clippings on the yard
actually help? The lot has been in this state for at least 20 years
and there is little or no topsoil on any of it. (We just moved here
couple years ago.) Suggestions appreciated.
