Tomatoes are one of the most popular garden fruits, according to the University of Rhode Island. Tomatoes are versatile fruit that have steadily become a dietary staple. Whether cooked or eaten raw, tomatoes are low in calories and contain both lycopene and vitamin C. Growing giant tomatoes requires careful preparation and proper care.
Turn the soil in the planting area thoroughly about two weeks prior to planting the tomato plants. Cultivate the soil down to a depth of 10 to 12 inches. According to the University of Rhode Island, tomatoes grow best in deep, loamy, nutrient rich soil that offers good drainage.
Lay out, over the planting area, a 2- to 3-inch layer of organic media. You can used aged manure, dehydrated compost, leaf mold or other like material. Mix the organic media into the soil thoroughly using a garden fork or a shovel.
Mix into the soil 1 1/4 to 1 1/2 pounds of 5-20-20 or 5-10-10 fertilizer for every 50 square feet of area you are going to plant.
Create planting rows spaced about 5 feet apart. In the center of each row, dig holes that are spaced approximately 3 feet apart. Each hole should be about twice the diameter of the growing container and about the same depth.
Remove a tomato plant from its growing container and place it into a previously dug planting hole. Pop out a tomato plant using your thumb, if you're planting from planting packs. If the tomato plants are growing in 3- or 4-inch pots, turn the pot upside down while supporting the plant, and pull the container off the root system. After placing the plant, fill the hole.
Fertilize the tomato plants every 14 days using a fish-based liquid fertilizer. Read the directions so you will know how much fertilizer to use per gallon of water. Once the tomato plants are growing, eliminate all but one stem from the plant. Make sure to remove any suckers that sprout (suckers of side-shoots that form off the main stem). Spread 2 to 3 inches of leaves, straw, grass clippings or other similar material for mulch around each tomato plant once the first set of flowers appears.
Remove all but two or three tomatoes from each plant once they first appear. Place a tomato cage around each tomato plant, to offer support as each plant grows. Water the tomato plants with the equivalent of 1 inch of water a week, if there is no rainfall.
