What is the benefit of using red plastic mulch in my garden?
Red plastic mulch reportedly helps some crops go gang-busters. Tomatoes do well with it because the red light reflects onto the undersides of the leaves and triggers a physiological response that causes the plants to grow large and mature more fruit. Red mulch raises soil temperature and reduces the incidence of leaf blights. Melons, squash and cucumbers reportedly do better with red mulch as well.
