Weed Preventer
I have been using this product for 3-4 years. It helps to avoid growing of weeds between my tomato plants. It almost all deteriorates by end of a season. To allow more water to the plants, I punch about 1/2" dia. holes with slantly cut PVC pipe around them. I gave 4* because it deteriorates somewhat faster than I would like. My season lasts from mid of May to end of October.
