Standard black mulch film for suppressing weeds, reducing evaporation, and increasing soil temperature to encourage earlier crops and higher yields. Average soil warming of 3–5°F at the root zone. Flexible and durable. Easy to install and remove. Larger sizes are embossed (dimpled), allowing extra stretch for a snug fit over raised beds and better soil contact when applied with a mechanical mulch layer. 1.0 mil polyethylene.
