Leaching In Plants And Soil What Is Leaching

Pure sand is probably the best leaching type, but isn't very hospitable to garden plants. In general, the more sand your garden soil has, the more likely it is that you will have excess leaching. On the other hand, soil with more of a clay component presents less of a leaching problem.
