How to Grow the Biggest Tomato


Tomatoes are fast-growing garden vegetables that are relatively low-maintenance and hardy. They are the classic addition to the backyard garden. Employ several tomato plant care tactics, such as fertilization and selective pruning, to limit the number of fruit per plant, to boost your tomato plant's health and to increase the size of your tomato fruit.

Step 1

Choose a sunny garden garden plot. Tomatoes thrive best in full sun. If your tomato plot is shaded, prune back surrounding vegetation or trees to increase sunlight, or move the garden plot to a new location.

Step 2

Water your tomatoes. Tomato fruit are made up of mostly water, and too little water may result in poor fruit size. Give 3 to 4 quarts of water to each plant per day, and boost this to 4 to 6 quarts of water once the plant begins producing fruit.

Step 3

Feed the tomatoes. Giving your plants the right amount of nutrients ensures they have the energy for optimal fruit production. Apply a standard low-nitrogen garden fertilizer with a nutrient ratio of 5-10-10 or 8-16-16 according to the fertilizer label's guidelines, since potency varies by product. Fertilize when you plant the tomatoes and again when the plants produce their first set of flowers.

Step 4

Cut off extra tomato fruit before they develop. Allow just one to two tomatoes to grow per plant at a time. This maximizes the tomato fruit's size since the plant channels all of its energy into developing only a few fruit.

Tips and Warnings

  • Tomato pests, such as beetles or white flies, can stress the plant and decrease fruit size. They may even physically destroy your fruit. If your plant is attacked by insects, mist the plant with an insecticidal soap or a general garden insecticide spray.
