How to Grow Huge Tomatoes


The world's largest tomato weighed 7.76 lbs. and was grown in Oklahoma, according to Master Gardeners at Ohio State University's Cooperative Extension. The vine on which the tomato grew was also a record-breaker: 53.6 inches in length. The variety of tomato grown by the gardener, was the delicious. Other varieties suggested by the Master Gardeners include Dutch man and giant Belgium. Plant the tomato plants in the garden in March, according to Gordan Graham, father of that huge tomato, if you want to grow your tomatoes really large by harvest time.

Step 1

Choose a location in which to plant the tomato. It should get full sun all day.

Step 2

Amend the soil in the planting area by mixing in 4 inches of compost or well-rotted manure. Use the gardening fork to mix it to a depth of 8 inches.

Step 3

Dig a hole the same depth and twice the diameter of the pot in which the tomato plant is growing.

Step 4

Gently remove the plant from its pot and place the roots in the hole. Pack the soil well around the base of the tomato plant.

Step 5

Drive a stake 1 to 2 feet into the ground, placed 3 feet from the tomato plant, on its north side. As it grows, you will need to tie it to the stake with soft, fabric strips or plant ties from the gardening center.

Step 6

Cut the bottom off of a 1-gallon plastic milk jug. Place the open end of the jug over the tomato plant to protect it. Take the cap off the jug during the day and replace it at night. Remove the jug when there is no longer a danger of frost.

Step 7

Give the tomato plant at least 1 inch of water per week. If the weather is particularly dry, increase the frequency with which you water to twice per week.

Step 8

Fertilize the tomato plant every two weeks with fish emulsion, diluted to half the strength recommended on the packaging.

Step 9

Spread a 3-inch layer of mulch around the base of the tomato plant when it begins to flower.

Step 10

Pinch off any suckers (small sprouts of growth between the branches and the main stem) before they are 1 inch long. Allow just one main stem to grow.

Step 11

Remove all fruit with the exception of two or three from the bottom of the vine. Remove, as well, any new leaves or flowers that form.

Step 12

Pinch off the top of the plant when it reaches the top of the stake. This will direct the plant's energy into the fruit.
