The red color stimulates stem strength and fruit production in tomatoes by simulating the conditions of overcrowding. Your plants not only produce more heavily, but they get stockier to be able to support that additional bounty! And USDA tests show that plants using Tomato Mulch bore tomatoes weighing an average of 46 percent more than others! Wow!
The sheet of mulch is 18 inches wide and 25 feet long -- enough to cover an average row of 10 tomato plants. Set the mulch on either side of the stems, bringing it together so that there is no gap of earth between the two sheets. Then start harvesting big, heavy fruit all summer!
