To grow tomatoes in your garden, begin by sowing tomato seeds in flats about six to eight weeks before the last frost. Keep the plants in a warm window, water them regularly and transplant them outside when the soil temperature is above 55 degrees Fahrenheit. Tie the plants to a stake for support, keeping the soil moist throughout the growing season.
Many people choose to grow tomatoes from transplants purchased at a garden supply store rather than growing them directly from seed. This method is less time consuming, and the chance of accidentally killing the plants is lower. When growing tomatoes from transplants, whether started at home or at a garden center, place the transplants outdoors to harden off for a week before planting them in the soil. When it's time to put them in the ground, dig wide planting holes at least 2 feet apart, and sprinkle a teaspoon of Epsom salts into each hole before inserting the tomato plants. Epsom salt contains magnesium, which promotes strong plant growth.
Water your plants well, and keep them on a regular watering schedule to keep the soil moist. When the plants start to sprawl out, tie them to stakes with twine to keep them upright. Most varieties produce fruit within 80 days. Pick the fruit as it ripens by gently twisting the tomatoes off of the plant.
