How to Grow Large Tomatoes


Anyone with a passion for tomatoes would love to grow large tomatoes; the ones in which one slice covers the bread. As the weather begins to warm and gardens become established, many wait in anticipation for that first tomato of summer. If you've decided this is the year that you're going to try growing large tomatoes, you're in for some excitement. Assuming you know the basics of growing tomatoes, a few tips can ensure your tomatoes are those one-slice tomatoes that friends and neighbors crave.

Step 1

Choose the right variety. One can use every tip and trick for growing large tomatoes, but if the tomato variety is one that does not produce large fruit, it simply won't work. Some of the large tomato varieties: Beefmaster, Celebrity, Champion, Delicious, Fantastic, Genovese, Golden Boy, Golden Jubilee, Ida Gold, Jubilee, Supersteak, Top Sirloin, Whopper and Yellow Oxheart.

Step 2

Plant tomato plants at least 2 feet apart if caged or supported. Tomatoes that are not supported will need two to three times more room. Know the variety you are planting and plant according to the tomato plants' mature size, not the size of the transplant.

Step 3

Avoid planting tomato plants in shady spots. Plants require the energy of the sun to produce fruit. While the plant may grow exceedingly well with less light, tomatoes require at least six hours of full sun to produce quality fruit.

Step 4

Fertilize using a 1-1-1 ratio organic fertilizer. Using a fertilizer that you have on hand can defeat your efforts to grow large tomatoes. Tomatoes require equal amounts of nitrogen, phosphorus and potassium.

Step 5

Prune tomato plants to help achieve fruit size. Removing the side shoots and suckers that form from the primary stem will increase the size of the fruit, while decreasing the total yield.

Step 6

Water tomato plants as the ground begins to dry out. Do not allow the ground to dry out entirely, which will prompt blossom-end rot. Applying organic mulch or compost around the tomato plants will help to preserve moisture.
