The ABCs of Tomatoes, Dirt, and Sun

Tomatoes are one of the most popular vegetables in the world. Some would call them a fruit, since they are officially classed that way. But let’s forget that for a moment, especially since they can be considered vegetables by nutritionists.

The first step in growing tomatoes is to get some seeds, which you can acquire from any ripe tomato or seed store.

The next step is to choose a location for your plants. Tomatoes need a lot of sun, so they should be planted in an area that receives at least six hours of sunlight each day.

They also need well-drained soil, so choose a location near an area where water can be drained without causing problems for other plants or lawns.

Those are just the basics, so read on to find out everything you need to know to grow plump, delicious tomatoes for yourself!

Planting the Seeds

It is important to plant tomato seeds in containers, because they can grow roots and develop a better root system. It is also essential to produce them in the right depth and use potting soil that has a good drainage system.

Tomato plants need enough nutrients to grow healthy, so it's necessary to supplement them with the right type of fertilizer.

It is also essential to keep the soil moist but not wet and keep the temperature at a steady level. Tomato plants need a lot of water, but too much water can cause root rot. When the leaves start to yellow, it is an indication that too much water is in the soil.

Tomatoes thrive in full sun, and they will require at least eight hours of direct sunlight each day. During the afternoon, they can tolerate some afternoon shade. This can either be natural or artificial.

Preparing the Soil

Once you find the perfect spot for your tomato plants, it's time to prepare the soil by adding some organic matter like compost and aged animal manure and mixing it with your native soil. Now you are ready to plant your tomato plants.

Dig a hole that's twice as deep as the longest tines of your spade. Fill it with a mixture of compost and soil, add water, and then place the tomato plant into the hole.

It's important to follow these steps, because otherwise your plants may not get enough moisture and sunlight.

Keep the Soil Loose by Adding Organic Matter

The soil needs to be loose enough to allow the roots of the plant to grow, but not so loose that it packs down and becomes too dense. The best way is to add organic matter such as leaves, grass clippings, compost, or manure. It can also be done by tilling or digging up at least 6 inches of organic material from an area nearby and adding it back into your garden bed.

It is also important to keep your soil moist. So mulch the soil with hay or straw around the plants to prevent evaporation.

Note: Allow the soil to break down for two weeks before planting your tomatoes. Once the soil has thawed, plant the tomato plants in the newly prepared space.

Watering Requirements

Whether you are growing in containers or full-grown in the ground, watering is essential to the growth and care of tomato plants. The amount of water your plants need varies with the climate, growth rate, and soil moisture.

Make sure to water the soil at least 6–8 inches deep around the plant. In general, you should water your plants daily, although this can vary depending on the amount of rainfall and temperature.

To determine how much water to give your tomato plants, you should check the moisture of the soil by using a soil auger or shovel. The soil should crumble when the soil is cool to the touch. When watering, make sure to fill the entire root zone of the plant, which typically extends from ground level to about 18–24 inches. Make sure you keep a water bottle near the plant and refill it as needed.

Fertilizing Your Tomatoes

The best way to ensure that your garden is ideal for growing tomatoes is to test the soil. The results of an analysis will show the number of significant micro-nutrients present in the soil. They will also provide suggestions on what amendments you should use to improve the soil's quality.

Fertilizing your tomato plants can help ensure that they will produce fruit that is both delicious and plentiful. Additionally, using a wooden stake to prop them up will help prevent them from developing yellow leaves, which may be an indicator of fungus or another disease.

Follow a Feeding Schedule

When fertilizing tomato plants, make sure to follow a feeding schedule. Tomatoes need frequent feedings. If you do not fertilize every day, you'll end up wasting money on fertilizer. Instead, fertilize every two weeks.

Fertilizing should be done at least 6 inches away from the base of the plant. Depending on where you live, you can fertilize your plant once a week.

Tomatoes need a steady source of nitrogen and potassium. In general, their fertilizer ratio should be 6-to-4 for nitrogen and 8-to-32 for potassium. In addition to using these organic fertilizers, you can also make your own by composting banana peels and potato skins.

After you have completed the planting process, you can use a slow-release fertilizer to provide a steady supply of nutrients. You should place the fertilizer about 3–6 inches away from the stems of your plants. In addition, make sure to keep the plant well-watered during this time.

After it has reached maturity, the plant should be able to bear fruit, so you can continue fertilizing and reap the rewards of growing tomatoes.

Providing shade for your tomatoes is important if you live in a very hot climate.

Protecting Tomato Plants From Daytime Heat

During the hottest part of the day, tomatoes are vulnerable to excessive heat. To combat this, you can choose tomato varieties with higher heat tolerance. Then, just keep them watered and protect them from the hot afternoon sun. Listed below are some tips to help protect your tomatoes.

  • A heatwave is an especially tough time for tomatoes, so protect them with shade cloths or other protective measures.
  • Aside from shady areas, you can also cover the tomato frame with a frost cloth. Frost cloth is available in different materials. It should cover the entire structure, including the soil line. Be sure to secure the fabric in place using bricks, large stones, ground staples, or tent pegs.
  • To protect your tomato plants from the heat of the day, you can place clip lights along the ground. Be sure to place them far enough from the plants to avoid touching the frost cover fabrics or foliage.
  • Keeping the soil moist will also help. The moisture in the soil will radiate heat upwards, warming the plants nearby.
  • To keep your tomato plants cool at night, consider burying them under a heavy mulch. Mulch should be applied to a depth of six inches.

The Effects of Extreme Heat on Tomato Plants

In extreme heat, tomato plants may fail to pollinate. During prolonged heat, flowers on the tomato plant will fall off. The leaves will also droop, exposing the fruits to the intense sunlight.

When the temperature drops, the plants will begin to produce tomatoes normally. After that, temperatures will return to normal and they will flower. But in the meantime, they may have a difficult time pollinating.

Pruning Tips

In addition to promoting increased yield, pruning tomato plants helps prevent disease by eliminating conditions that encourage the growth of fungus and other pests, as well as by reducing plant height and promoting healthy growth.

A tomato plant with unpruned vines forms many overlapping side shoots that become unsupported and susceptible to soil-borne diseases. In addition, this type of plant produces more side shoots, resulting in denser foliage and an increased risk for disease.

Sanitation and Proper Technique Are Key

The process of pruning tomatoes requires knowledge of what to prune and how to do so in a sanitary way. The basic rule is to remove any foliage that contacts the soil and prune only the lower 12–16" of the plant. This method also avoids damaging the remaining foliage. This is important as many common tomato diseases reside in the soil, such as early blight and bacterial leaf spot.

When pruning tomatoes, keep in mind that you should pinch off the tips of suckers when they're small. The tip of the sucker will be a smaller wound, so pinching it off will have less impact on the plant than removing large side stems. Besides that, the remaining suckers will grow new suckers.

Proper tomato pruning will encourage the plant to focus more energy on its fruit rather than its foliage. The result will be fewer fruits and larger ones. Moreover, it will increase sunlight exposure, allowing for more flowering and reduced chances of pests.

As long as you prune properly, it will help you to grow a tomato plant with fewer leaves. Though if you prune your plant too hard, you may risk sunburn and blossom end rot.

Pruning Indeterminate Tomato Plants

If you want a consistent crop of tomatoes, consider growing an indeterminate variety. These varieties will produce fruit throughout the summer and fall.

Indeterminate tomato plants are generally bush-type, while determinate varieties grow vine-like. However, they can benefit from pruning to produce fruit earlier. Without pruning, indeterminate tomato plants will grow uncontrollably, and they'll require serious support.

Before beginning pruning, use clean pruning tools and disinfect them with hydrogen peroxide. Identify the main stem from where the tomato plant grows. Once you have identified this, you can proceed with the pruning process.

First, remove any lower leaves. The lower leaves are often infected with soil-borne diseases. These can cause blotches and leaf spots, and even early blight.

Indeterminate tomato plants tend to produce a large number of suckers during the growing season. By removing these, you can prevent the disease from spreading throughout the plant. Be sure to remove all suckers that sprout below the first flower cluster. After the growing season is over, the suckers will die off, and the tomato plant will look healthier.

Pests, Diseases, and Other Potential Problems

  • If your tomatoes are not producing fruit, you may have an insect problem. Aphids are pear-shaped bugs that love to live on tomatoes. Whiteflies and spider mites are pear-shaped and move when your plants are jostled. If you notice any of these pests, you can try an organic remedy such as insecticidal soap.
  • Moisture fluctuations can also cause cracked fruit on tomato plants. This should be left on the plant until the fruit has developed into color.
  • If your tomato plants are still not producing flowers or fruit, they may be receiving too much nitrogen.
