A mulching structure for covering the soil around the stem of a growing plant and over the roots thereof to screen sunlight from the adjacent soil and thus minimize the growth of weeds. The mulching structure also allows water from irrigation or rain to flow therethrough to the soil. The mulching structure includes a first wall made out of a substantially impermeable material. The first wall is provided with a first wall aperture extending therethrough. The mulching structure also includes a second wall made out of a substantially impermeable material. The second wall has a second wall aperture extending therethrough. A wall spacing structure extends between the first and second walls for maintaining the latter in a spaced relationship relative to each other. The mulching structure is so configured as to allow through flow of the water between the first and second wall apertures while preventing through passage of the light rays from the first wall outer surface to the second wall outer surface. The first wall and the second wall extend in a generality parallel relationship relative to each other. The first wall aperture is configured, sized and positionned so that its geometrical projection on the second wall in a direction perpendicullar to the first wall is offset relative to the second wall aperture. Similarly, the second wall aperture is configured, sized and positionned so that its geometrical projection on the first wall in a direction perpendicullar to the second wall is offset relative to the first wall aperture.
