An apparatus is provided which promotes and enhances the development of microorganisms in the ground, which microorganisms are indispensible for promoting the growth of vegetation, including plants and trees, by recycling water and circulating air to the zone in which the roots of the vegetation are located. The apparatus includes a relatively severely flared, frustoconical skirt portion which is adapted to cap the roots of vegetation within the ground. It also incorporates a small, generally cylindrical collar which extends above the ground and which surrounds the trunk of the vegetation being protected. A plurality of drains, formed by channels along the interior surface of the skirt and collar, extend over the length of generatrices of the apparatus and serve to conduct water and air to the roots of the vegetation. The apparatus is formed by two identical members, each of which has a dimension greater than one-half of the collar and one-half of the skirt. These two portions overlap when attached and are connected by a flexible band or similar member. In addition to maintaining a fertile zone in which the roots of plants, trees and other vegetation can flourish, the apparatus protects plants from ingrowth of undesirable weeds and damage which occurs from the use of small agricultural tools. |
