White on Black Mulch

Great for cooler temperature crops. Lettuce, cauliflower, broccoli and other cool loving crops will thrive in this dual-color, embossed plastic mulch. White plastic faces upward, keeping soil temperature down while increasing the amount of light available to the plant. The black plastic underside allows less light to reach the ground, which helps to control weeds. The coextruded white-on-black mulch can result in a decrease in soil temperature up to 12 degrees, even as it reflects light back into the plant canopy. During spring and fall production, the increased light availability promotes faster growth and larger yields, offering an added value over non-coextruded white mulches. Mulch is 1.5 mil. thick and is embossed.

The Harris Seeds company began catalog operation in 1879. It evolved from the efforts of Joseph Harris who was extremely successful in the selection of superior strains of vegetables and grains. The company became wildly popular because of his basic business philosophy - "Offer my customers a quality product at a fair price and they will return."
