Leaching In Plants And Soil What Is Leaching

Apr 04, 2018· Leaching of potted plants. Leaching in plants can happen in potting containers. Once the chemicals have drained down through the soil, they can leave a crust of soluble salts on the surface, which makes it hard for the soil to absorb water. Removing this crust with water is the other type of leaching.
