Secrets to Success »
Plant deeply so that two-thirds of the plant is buried, stem and all. The buried stem will sprout roots, adding to the strength of the plant. Fertilize when planting and during the growing season with Bonnie Herb & Vegetable Plant Food.
Water regularly. Tomatoes need steady watering to develop to full size and to prevent cracking and blossom end rot. To keep the soil moist, mix compost into planting holes, and mulch around the plants after the soil warms. Watering with a soaker hose is best to keep the foliage dry. Wet leaves encourage disease.
Support plants on stakes or a sturdy wire cage to keep fruit off the ground. This helps prevent disease.
Harvest and Use »
Pick red, vine-ripe tomatoes to slice or quarter on a plate, in a salad, or on a sandwich. Use green ones for fried green tomatoes or tart sauces. The red tomato is considered a “superfood” because it’s full of vitamins and antioxidants, including cancer-fighting lycopene.
