Abstract: A method of draining moisture from a soil includes steps of providing a first surface in contact with the soil, wherein the first surface is permeable and non-absorbent; providing a plurality of granules in contact with the first surface, wherein the plurality of granules is permeable and non-absorbent; and providing a second surface in contact with the plurality of granules, wherein the second surface is permeable and non-absorbent. The method includes dispersing the moisture via the first surface, the granules, and the second surface, distributing the moisture via the first surface, the granules, and the second surface, and draining the moisture via the first surface, the granules, and the second surface. The dispersing, distibuting and draining are caused by gravitational and capillary effect. The method is performed by a potting insert. The potting insert is located in a potting container, below soil in the container.
