The tree root aeration and nutrient delivery device shall be manufactured specifically for this purpose. It shall be constructed of a single tubular highdensity polypropylene polymer. The root aeration device shall contain sidewall openings in a horizontal and vertical pattern, equally spaced, that span the entire length and circumference in a uniform manner providing a 5:1 ratio of sidewall openings area to total surface area equally. The sidewall openings may number in the thousands depending on the length and diameter of the root aeration tube model. The root aeration device shall be capable of having the sidewall shape distorted without damage to the device. The top and bottom end caps shall be constructed of a high-density styrene polymer. The top end cap also contains the air convection insert device which shall have a flexible central tube that extends from the top cap into the tube’s interior 5”. The flexible tube shall have an outside sidewall dimension of .3125 “, and an internal diameter of .25 “. The top cap has additional ¼” openings to promote the convection of internal air currents for fresh air transition for increased Oxygen and Nitrogen content.
