An irrigation device for facilitating growth of a plant includes a mat that is air and water permeable and has an opening through which a plant extends. A slit extends from the opening to a peripheral edge to facilitate placement of the mat around the plant. A drip tube is disposed within the mat between upper and lower surfaces, and has an open end connectable to a water source, and a series of emitters along the length thereof permitting water to exit the drip tube and through the lower surface of the mat. Stakes may extend through the mat and direct water into the ground towards roots of the plant.
