Tested by the U.S. Department of Agriculture, this mulch increases tomato yield an average of 20%. In addition to keeping soil moisture constant and controlling weeds, it warms soil to stimulate early plant growth and reflects specific light frequencies to improve yield. Perforated so water and air reach roots. Use for tomatoes, strawberries, red peppers, melons and other above ground fruit bearers. Reusable for 2-3 seasons. (8 precut 3’ x 3’ sheets)
