Plant watering and root protection device

A plant watering and protecting assembly adapted for protecting roots from underground rodents and for containing overhead water in a circumferential area above said roots for drainage into said roots, comprising a plurality of interlocking pieces adapted to removably interlock with one another to form a continuous annular sheath for underground encircling of said plant root system;

• each of said pieces accommodating securing means to which a solid chemical stick can be secured wherein each of said pieces is a single-molded form comprising a vertically-elongated sheet of stiff material, the upper edge of said piece comprising a curled lip wherein the degree of curling of said lip is sufficient to form an upper curvilinear edge to said piece and said curvilinear edge is adapted with a continuous groove extending along the entire length of said curvilinear edge, said curvilinear edge forming a berm for surrounding the base of a plant above ground in order to confine standing water within confines of said berm;
• the two vertical edges of said piece being of sufficient length to extend to an underground depth beneath the entire, or a major portion of, said root system;
• each of said vertical edges being adapted with interlocking engaging means for engaging and interlocking with a corresponding interlocking engaging means on a vertical edge of another of said pieces.
