Silver Mulch has been University proven to increase yields up to 20 percent and lowers insect problems. The extra light from the reflection repels insects and the increased light from reflection is one of the reasons your yields increase. The bottom of the plastic is black to cool the soil when needed and suppress weeds. Good for all types of plants and great to use in organic gardens. Just a review, Studies at the University of California Kearney Ag Center, test show that plants grow better and more rapidly over reflective mulch than ones without any mulch. Both harvest yields and coloring of fruit increased with Silver Mulch. Silver Mulches reflect sunlight up into the undersides of the canopy, thereby increasing photosynthesis, leading to rapid growth. Helps control soil temperatures. Repels aphids. Helps conserve soil moisture & soil structure.

Red Plastic Mulch is primarily used on tomatoes for an early harvest. According to researchers at Cornell and Clemson universities, when tomatoes are grown on red mulch they have higher yields, stronger stems and ripen earlier. Research has also found that red mulch reduces nematode damage. The plant responds to the high proportion of reflected far-red from the red mulch by growing taller and putting out more leaves. Eggplant have also shown increased yields when grown on red. It is the color of the mulch that changes the intensity of certain wave lengths of light that in turn has an impact on plant growth and subsequent yields. Studies by Penn State University show tomato yields have been as much as 20% higher with red plastic mulch than with black. Red mulch reflects intensified red light to the developing plants which increases their photosynthetic capacity. There is more reflectivity early in the season when more of the mulch is exposed to light. This red plastic mulch is made of high quality, durable plastic that is 1.0 mil thick and lays well over flat or raised beds. It has season-long integrity and is easily removed from the field after harvest.
