Leaching of soil. The soil in your garden is like a sponge. When rain falls, the soil near the top absorbs as much as possible, keeping the moisture available to the plants growing there. Once the soil is filled with all the water it can hold, the water begins to leak downward through the layers of rock and subsoil beneath your garden.
