Steps
#1 Buy a tomato plant from a nursery and transplant it to your garden for the first-time grower. More experienced growers will find it easy to start their own tomatoes from seed, beginning, as appropriate, in a greenhouse or sunny window indoors.
* In most cases, there's no reason to pay extra to buy larger plants.
* Good first-time growers’ varieties include Better Boy, Creole, Big Boy, Early Girl, Brandywine, Celebrity, Lemon Boy, or just about any cherry or grape tomato variety.
* Plant several varieties rather than all of one type-- this ensures a steady harvest. As a rule of thumb, it's good to have two plants for each member of the family who will eat tomatoes. If you plan on canning or making salsa, use up to four plants per person.
* Plants usually cost US $4 or less.
#2 Choose a sunny spot to place the plants. Place tomato plants in a site receiving full sun (7 hours or more daily) Tomatoes need lots of warm sunshine for optimum taste.
#3 Prepare the garden bed by adding lots of compost (5 to 8 pounds per square foot/25 to 40 kilograms per square meter) to the soil. Turn compost into the top 3 inches (6 to 8 cm). Tomatoes demand a growing medium rich in organic matter. If you don't make your own compost, use store-bought compost or composted manure available in the 40-pound bags. Compost or Manure is usually less than US $5 per 40-pound bag.
# 4Transplant the tomato deeply. Bury about 75% of the plant. It’s okay to bury some of its leaves. New roots will emerge along the buried stem, giving the plant a development boost; a new transplant needs to focus on root production.
#5Give each plant about 1 gallon (about 4 liters) of warm water (about 80 degrees F/ 27 degrees C) within ten minutes of transplanting to avoid transplant shock.
#6 Space tomato plants 18 to 36 inches (45 to 90 cm) apart; space them half the suggested distance in warmer climates, especially if using tomato cages. The normal distance recommended is for plants allowed to bush out hugely on the ground, while planting closer together in cages allows the plants to shade each other's fruit, helping prevent burn and allowing a sweeter flavor.
* Don't forget to leave yourself enough space to get in between the plants to water, weed, and harvest. Those cute, little seedlings may not remain that way for long.
#7 Continue to water about 16 ounces (about 500 ml) of warm water per plant every day for the first 7 to 10 days after transplanting.
#8 Wait a week or two after transplanting,and then place a mulch of straw, dried grass, or pine needles to control weeds and keep the soil moist during dry weather. The mulch should be about an inch (2.5 cm) thick and surround at least a circle 12 inches (about 30 cm) in diameter around the stem. Pine needles are especially good for helping raise the acidity of the soil.
#9 Ensure that plants are receiving 1 to 3 inches (2.5 cm to 7.6 cm) of rain weekly. If not, give each plant about 2 gallons (about 7.5 liters) per plant per week, beginning 14 days after transplanting.
* The tomato plant should be watered 2 to 3 times weekly (so, water each plant with about .75 to 1 gallon each time (about 3 to 4 liters).
* It's okay in hot or dry weather to water even more frequently with larger volumes.
#10. Consider using a tomato cage or a stake to support the tomato vine about 14 days after transplanting.
* A stake should be at least 0.5 inches (1.3 cm) thick and 6 to 8 feet (1.8 to 2.4 meters) long. Pound stakes about 12 to 24 inches (30 cm to 60 cm) deep, at least 2 inches (5 cm) away from the plant. Secure the plant to the stake using loose knotted double-loops that won't strangle the plant. Stakes can be made of bamboo, scrap wood, electrical conduit, or iron bar.
* While it is less common, they can also be vined on a trellis or fence, like grapes, beans, squash, and other vining plants. This can produce especially large yields, but is less popular because tomato plants grow so large and bulky.
* A cage should be at least 48 inches (1.2 m) tall, even taller if you grow the plant well. Some tomato plants can be more than six feet (1.8 m) tall in cages. Cages have a tendency to bend if the plants get heavy, and sometimes collapse in summer storms. Carefully pull leaves and secondary stems inside the cage as the plant grows. Cages cost less than USD $4 each.
* If your plants routinely outgrow purchased tomato cages, get some hardware cloth (wire mesh) with a broad grid and cut it and roll it into wide cylinders to make your own, larger cages. Bend the wire ends around the wires on the opposite end, making a circle. This type of cage may need a strong stake for support.
#11. Choose whether to use use chemical fertilizers. Tomatoes can grow very well organically, provided the soil is well enriched with organic matter. If you do use chemical fertilizers, try using half the recommended concentration per gallon (using package directions), but fertilize twice as often, in order to avoid the stress caused by the feast-famine of the longer fertilization gaps.
* Over-fertilization can cause plants to grow too quickly, leaving them more susceptible to disease and insects.
* Remember that your goal in growing tomatoes is fruit, not leaves. Fertilizers, especially when used in excess, may cause the plant to produce more leaves and foliage.
#12. Shake your plants gently once or twice each week for about 5 seconds once flowering begins. According to the National Gardening Association, shaking the tomato plant increases fruit production by more evenly distributing pollen.
#13. Watch for fruit to appear 45 to 90 days after transplanting. Tomato plants usually have small, green fruit to start. Wait until the fruit is of good size with a bright, deep coloring. This means that the fruit is ripe and ready to pick. The texture of the fruit can also determine if it is ready to pick. Ripeness is usually determined by a slight softness. Be careful not to squeeze too hard and bruise the fruit. Also, be careful of allowing it to become overly ripe, which results in a very soft tomato.
