Poor Drainage in Garden Areas
Winter is often a good time to fix areas in the garden where water sits and does not drain properly. Such areas often harm plant roots due to poor oxygen levels in the soil. Consider adding good topsoil so water doesn’t sit. Be sure to till or spade the area to mix the new topsoil and the underlying existing soil. Plant roots do not like to cross distinct barriers caused by one type of soil sitting on top of another. Internal drainage can be improved by adding organic matter such as peat moss, rotted hay, cotton burrs, rotted silage, tree leaves or compost. This can be done by adding a 2- to 4- inch layer of organic matter to the surface of the soil and tilling or spading in as deeply as possible. (Ward Upham)
