How to Make Clay Soil Drain & Be Fertile

Clay soil is the ideal ground for certain plants, such as oaks, maples and poplars. But its compacted structure prevents the development of vegetables and most flowers, whose roots require an aerated environment where water, nutrients and air flow freely. To improve your garden soil to the point it can support those crops, incorporate store-bought topsoil and organic matter into it. Compost, grass clippings, pine bark and dead leaves are some amendment options. Top it off with manure to fertilize the garden bed.
