Skip to Introduction

The tomato is a warm season crop. With special production practices you can produce your first tomatoes in 60 days. This crop can be grown for production from June through November by choosing the right varieties and production practices. Generally, tomatoes require a large investment in time and labor, but increase in intensity of management is repaid by increased yields and profits.


Skip to Varieties*

There are many good tomato varieties. The choice of varieties is important to orderly production, earliness, shipping quality, and disease resistance. Here are some varieties which do well in your part of North Carolina, unless noted they are harvested as breakers.

Recommended varieties change over time, check with your county extension agent for the latest recommendations.

Select a well-drained soil with high organic matter. Test the soil for fertilizer and lime requirements and nematodes. A pH of 6.5 is best. If a nematode test is not done use a fumigant type nematicide.


Skip to Fertilization

Tomatoes use a lot of fertilizer. If soil is not tested, apply 400 to 600 lbs per acre of 10-20-20 in the Coastal Plain. In the Piedmont more phosphate will be needed. While the Coastal Plain soils may not need this much phosphate, half the fertilizer should be broadcast and the remainder banded 6 inches on either side of the row and 4 inches deep before transplanting. Side-dress with 150 to 250 lbs per acre of 14-0-14 or 15-0-14 just after the first blooms set fruit and again 3 weeks later. Sandy soil may require 13-0-44 and/or a third sidedressing.


Skip to Transplanting

It is best to grow your own plants (See AG-337, Vegetable Transplants). If this is not feasible, obtain plants from a certified plant grower. Transplant as soon as the danger of frost has passed or use sprinkler irrigation for frost protection. For early production use plants that have been grown in 3- to 4-inch containers.

Starter Solution

Skip to Starter Solution

Water young plants with a starter solution. This is particularly important if bare-rooted plants are used. Commercial water- soluble fertilizers are available. Apply 1 cup of this solution per plant.


Skip to Spacing

The spacing depends on the variety, the training system, and the spray equipment. Rows are 4 to 6 feet apart. Determinate plants are usually spaced 18 to 24 inches apart.

Weed Control

Skip to Weed Control

Several good herbicides are avail-able for pre- and post-plant applications. Check with your county extension agent for the latest recommendations.

Plastic Mulch

Skip to Plastic Mulch

Black plastic mulch speeds maturity and increases yield. Methyl bromide can be used in conjunction with a plastic mulch. If plastic mulch is used, all fertilizer should be put down prior to laying plastic. If plastic is used drip irrigation will increase yields. Also, fertigation will help increase yield. (Consult AG-502, A Guide to Intensive Vegetable Systems and AG-489, Plasticulture for Commercial Vegetables).

Staking, Training, and Pruning

Skip to Staking, Training, and Pruning

Plants should be staked or trellised. For staking, drive a stake by every other plant leaving at least 4 feet of the stake above the soil level. Use plastic twine to form a support on both sides of the plant. The twine is wrapped around each stake. Consult AG-405, Commercial Production of Staked Tomatoes in the Southeast for a complete description of the stringing process. Remove all suckers up to the one just below the first fruiting hand. Remove suckers when they are small. Tomatoes can be grown without staking in the Coastal Plain but yields will be reduced.


Skip to Irrigation

Tomatoes need 1 to 1.5 inches of water per week either by rain or irrigation. A uniform water supply reduces blossom-end rot and results in higher yields and better quality. If drip irrigation is used it should be applied daily.


Skip to Grading

Radial cracks result from uneven water supply; cracking is reduced by certain varieties and uniform water supply.


Skip to Insects

Watch for flea beetles, aphids, colorado potato beetles, spider mites, and fruit worms. Consult your county agent for the latest control recommendations.


Skip to Diseases

Spray with recommended fungicides to control early blight, grey leaf spot and other foliage diseases. Spray once a week after first flowers appear. A spray pressure of at least 200 psi is needed for good coverage. (Use a sprayer with a piston or diaphragm pump.)

Harvesting and Packaging

Skip to Harvesting and Packaging

For shipping to distant markets, harvest fruits in either the mature green or breaker stage. For local markets, fruit should be allowed to develop more color. Package in the size container your market wants. Usually this is a 20-, 25- or 30-lb cardboard carton. Pack to assure uniform size, color, and quality.

Table 1. Tomato shipping and packaging
Tomato Sizes Diameter Inches
Jumbo 4 x 5 3 x 31016
Extra Large 5 x 5 21416 x 3616
Large 5 x 6 21116 x 3316
Medium 6 x 6 2816 x 21416
Small 6 x 7 2416 x 21016

If the crop is produced according to the steps outlined in this leaflet and no serious problems develop, the yield should be at least 10 to 15 tons per acre. Failure to do the job properly will seriously reduce yields. Some better growers exceed 20 tons/acre -- it depends on the job you do.

General Comments

Skip to General Comments

To be successful with fresh market tomato production, you should select a good variety, grow your own plants, have your soil tested and apply proper rates of lime and fertilizer, fumigate for nematodes or use resistant variety, stake or trellis, spray with proper chemicals for disease and insect control, harvest on time, grade properly, and have a previously arranged market outlet.
