The Good and Bad of Clay
Clay soils are not always bad. They hold more water than sandy soils and are often high in nutrients plants need. But clay soils can become so waterlogged that they deprive plant roots of oxygen, or so dry that they become too hard to dig in. To determine how much clay is in your soil, feel the soil. Run a pinch of moist soil between your fingers. The smoother it feels, the more clay it contains. If you can roll moist soil into a ball that hangs together, it contains more clay. Fortunately, you can find plants that thrive in clay soils and soil amendments that will help you grow a wider range of plants.
