Harvest sweet corn up to 2 weeks earlier! Increase soil temperatures without the labor and hassle of cleanup at the end of the season. The latest in plastic mulch technology, this photo-degradable mulch breaks down into water, CO2, and biomass throughout the season, saving you cleanup time and money. Photo-degradable mulch can be laid just like traditional plastic mulch and needs no extra care. The mulch breaks down over time, becoming brittle and then breaking apart. Mulch has an extra degrader additive aid in breaking down into smaller pieces. The speed of degradation varies with climate and sun intensity. Mulch is embossed and 1.25 mil. thick.
