Abstract: A slope guard device having one or more panels formed of impervious material, interlocking along their periphery to form a rigid annular unit capable of encircling a planted area on a slope. The panels define an inner side adjacent to roots, and an outer side remote from roots, said panels of varying heights to allow a user to customize a slope profile to a slope where taller panels support the slope above the planted area. Vanes extend from the panels and project inwardly from the inner side of the panels. The vanes direct root growth. Vents are attachable to some of the vanes each having an open upper end and open lower end, said vents providing additional structural support for the slope guard. The vents guide steel stakes that can be driven into the ground.

Abstract: A device for improving the delivery of water, aeration and fertilizer to the root system of plants provides an open-ended, water retaining, root barrier envelope which is placed around the root system of the plant, and a plurality of root deflector ribs for delivering water, aeration and fertilizer that extend downwardly along the envelope, and which are attached to the root barrier. Water, aeration, and fertilizer which are applied to the plant in the envelope will percolate downwardly through the upper portion of the soil surface embedding the root. The water will also move downwardly through the deflector ribs and then migrate inwardly through the perforations to a sub surface portion which is below the watered portion of the upper soil surface.
