Tomatoes are warm- and sun-loving plants. Full sun for at least 8 hours a day is essential for growing healthy crops. They also need a warm environment; tomato growing temperatures between 71 and 84˚F (22 and 29˚C) will be ideal. Though the crops can endure cool weather, their development will be stunted. At the same time, frost might become a problem for unprotected tomato plants, making them perish. 

Tomato plant water requirements are 1 to 2 inches (2.5 to 5mm) of moisture every week to grow and produce well. Variables such as temperature and plant density influence the rate of evapotranspiration and, thus, the crop water needs.

Plants growing in sandy soil fields might need more watering than those in clay soil fields because the former drain more quickly. However, the plant’s root system is extensive, reaching depths of up to 5 feet (1.5 m) in deep soils. As tomatoes grow, their root systems expand, allowing them to draw water from further down in the soil and making them less susceptible to drought.

Field-grown tomatoes thrive in nearly every type of soil (with the exception of heavy clay). Similar to other vegetables, they grow best in sandy loam soil that drains well and has a pH of 6.2 to 6.8. The soil for growing tomatoes should be high in phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg). The bare minimum for soil temperature is 57°F (14 °C); the optimum is between 65 and 70°F (18 and 21°C).

You should start soil preparation for growing tomatoes a couple of weeks before you plan to transplant seedlings. By plowing to a depth of 23.6 inches (60 cm) after removing weeds and crop residue, farmers improve drainage and soil aeration.

A week later, farmers commonly apply pre-planting fertilization, like aged manure or synthetic fertilizer. Although it would be more economical to spread the top dressing across the rows, application across the entire field might have a more positive effect on tomato plant growth. Right before planting, till the soil to a depth of 12 to 18 inches (30 to 45 cm) to encourage a more robust root system.

One more step before you can plant tomatoes is soil solarization, which is especially important in growing regions with cold soil during the planting season. This method helps keep the root zone at an ideal temperature of around 70°F (21°C) and prevents weeds from growing. When it comes to covering their rows, some farmers prefer green or black infrared-transmitting (IRT) polyethylene, while others use standard 1–1.25 mil black plastic.

Farmers can get a head start by purchasing and planting pre-grown tomato transplants. However, if you want to grow your plants from seeds, which gives you more control over the transplanted material, there are a few things to keep in mind.

A high-quality transplant takes about 5–7 weeks to grow. Maintaining nighttime temperatures over 60°F (15°C) encourages fast development. The average height of the transplants is 8 inches (20 cm), and they each have about 3–5 true leaves. Remember that seedlings aren’t ready for transplanting until they grow a few true leaves.

Typically, “hardening” (i.e., artificially stressing) seedlings is necessary to get them fit for transplanting. This process, which may involve moving the seedlings outside for a regulated duration or other techniques, is intended to help the tomato acclimate to an outdoor growing environment. To simulate water stress, most farmers progressively cut off their crops’ watering. Usually, they’ll switch off the water supply 13–15 hours before the transplanting procedure begins and then turn it back on when it’s finished.

Once all the necessary preliminary operations are completed, it is time to plant tomatoes. The farm workers either make marks on the plastic film or in the ground to indicate where the seedlings will go. After that, they prepare holes and set the seedlings inside.

The tomato planting distance should be 18 to 24 inches (45 to 61 cm) between plants and 48 to 72 inches (122 to 183 cm) between rows. Indeterminate plants tend to grow larger, so be sure to give them more room. There won’t be as much of a chance of disease spreading if tomato spacing allows each plant to grow in the light and air.

How Long Does It Take For Tomatoes To Grow?

The tomato’s growing time depends on the variety. Small determinate varieties ripen faster than their larger counterparts, such as beefsteak and many heirloom varieties. The typical time to harvest tomatoes is between 60 and 100 days after transplanting seedlings and 100 and 120 days after planting the seeds. Some early cultivars, though, can be picked in as little as 50 days after being transplanted.

When And How To Harvest Tomatoes

The optimal tomato harvest time varies by growing region. The earliest fruits ripen in late spring and persist through the summer in regions with unusual growing climates, like areas of California and the Pacific Northwest. Late spring to early summer is the ideal season for harvesting fruit in the Mid-Atlantic. Fruits in the Northeast and Midwest growing regions begin ripening in July and keep up until the first fall frost. Meanwhile, heatwaves typically put a stop to the tomato harvest time in the South and Southwest at the beginning of June.

Choose the method of harvesting tomatoes based on the fruits’ final use. For instance, traditional manual harvesting is a better option for direct consumption or producing whole canned tomatoes, whereas mechanical harvesting is acceptable for producing sauces and concentrates. Self-propelled machines specifically designed to clear-cut plants and sort harvested fruits from plant residues are used in mechanized harvesting.

If you strive for high yields, keep in mind that commercial tomato growing relies on extensive planning and pinpoint execution. You can assure the profitability and sustainability of your farming business by growing the right varieties, preserving soil health and fertility, implementing pest and disease control measures, and adopting best practices across the whole production cycle.
