Understanding Clay Soil and How to Improve It - The Spruce
WEBJun 24, 2024 · Clay particles are extremely dense and resistant to water movement, which is not conducive to root growth. In clay soil, the bulbs of spring flowers simply rot over the winter, for example. However, it is possible to improve clay soil by adding organic matter, such as bark, sawdust, peat moss, composting materials, or manure to the soil.
