White on Black Plastic Mulch

Upper white layer reflects sunlight back on the plants, increasing photosynthesis. Black lower layer blocks light to suppress weeds. Less solar energy is transmitted to the soil, keeping soil temperatures lower. Growers on the Vermont Vegetable and Berry Growers Association listserv report that white-on-black mulch repels thrips as well as reflective silver mulch, while being easier on workers’ eyes. Recommended for cool-loving strawberries, onions, brassicas and lettuce. 1.0 mil. 4' wide.
