In studies at the University of California Kearney Ag Center, tests 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. Mulches in general also hold temperatures at consistent levels. In another study by the same group, aphid and whitefly numbers were lower in plants grown on reflective mulches. Reflective mulches were also shown to lower the numbers of cucumber beetles by 6 times in a study written up in Hort Technology. Apparently, insects are confused by the amount of sunlight being reflected up by silver mulch, so they are less likely to land on these plants. Silver mulch is also effective in weed control and prevents snails from crawling across the shiny surface. This hybrid metallized(on one side), polyethlene film is 20% stronger than other typical low density films. Engineered to be applied silver side up, for periods of 3 weeks depending on environmental conditions.
