Is there any good method to retain moisture in areas that are sloped? I spent quite a bit of time removing rocky lousy soil in areas along my driveway the past few years. To the point I put everything through a mesh screen (1/2 inch grid). The soil that was "approved" or made it through the screen was then mixed with a combination of cow manure and good decomposed wood chips, making it very fertile or so I thought. Problem is no moisture is retained so it dries out too fast. It's one of few areas that gets full sun that I'd like to see flourish.

I've given thought to digging out the soil this spring and placing some plastic sheathing under it? It would be perforated to allow some drainage. Bad or good idea? Areas in question are the tulip area on left of drive and fence line right of drive.
