The fruit production in tomato plants increases when you apply mulch around the plants during the growing season. The mulch increases soil moisture content and controls weed growth for increased air circulation. Red plastic mulch is believed to reflect the beneficial sun rays onto the plant foliage for increased growth. Purchase special red plastic planters at gardening stores or make your own by laying red plastic sheeting around the growing area.
Plant tomatoes in the spring season after there is no longer a danger of frost. Allow the plants to grow until the roots become established.
Purchase red plastic sheeting on a roll at your hardware supply store. A thin plastic used for table coverings is also available at party supply stores.
Clear all vegetative growth around the tomato plants in early summer once the plants are established.
Measure the tomato growing area and placement of each plant. Lay the sheeting out and cut 2- to 3-inch-diameter holes at the location of each tomato stem. Cut four slits around the hole for ease in pulling it over each plant.
Install the sheeting mulch in the garden by gently pulling it over each plant. Take care not to break any tomato branches.
Water the tomato plants during the growing season, making sure the water penetrates the soil at the base of each plant. Special care is required for watering plastic mulched plants, as water will not penetrate the sheeting.
