A Complete Guide to Growing Beefsteak Tomatoes in Pots


Beefsteak tomatoes are known for their large, meaty fruits. We will walk you through how to grow beefsteak tomatoes in pots.

Beefsteak Tomatoes Suitable for Container Gardening

When choosing a variety of beefsteak tomatoes for container gardening, it should be compact and has a short growing season. Patio Princess, Celebrity, and Bush Early Girl varieties are recommended. These plants tend to grow smaller but still produce abundant fruit.

Selecting the Right Containers and Soil

Pot Size for Beefsteak Tomatoes

It is recommended to use containers 20 inches deep with a diameter of 18-24 inches. This will provide enough space for the root system to grow.

Plastic plant pots are lightweight and easy to move. But they can overheat in hot temperatures. Clay pots are porous and can help with drainage. But they can also dry out quickly. Ceramic pots are durable and can retain moisture well. But they can be heavy and more expensive.

Make sure the containers have drainage holes at the bottom. Because waterlog can lead to root rot and other diseases. If your container does not have drainage holes, you can drill some yourself. You can also use gravel at the bottom of the pot to improve drainage.

Recommended Soil Types and Composition

Beefsteak tomatoes are heavy feeders. They require nutrient-rich soil for optimal growth. When choosing a soil type, avoid using garden soil. Because it is too heavy and may contain pests or diseases.

The ideal composition of the potting soil includes peat moss, perlite and vermiculite. Peat moss helps with moisture retention. Perlite improves drainage and vermiculite provides essential nutrients to the plants. You can also add a handful of compost or well-rotted manure to the potting mix to further enrich the soil.

Adding Organic Matter and Nutrients

You can also make your own organic tomato fertilizer. For example, combine equal parts of fish meal, bone meal, and kelp powder. You can easily find these ingredients at your local garden center. Simply mix the three ingredients together.

Regularly check the pH levels of your soil. Beefsteak tomatoes thrive in slightly acidic soil with a pH 6.0-6.8. You can use a pH testing kit to determine the acidity levels. Make any necessary adjustments using agricultural lime or sulfur.

How to Grow Beefsteak Tomatoes in Pots?

Planting Beefsteak Tomato Seeds or Seedlings in Containers

Start by filling the pot with well-draining potting mix. Avoid using soil from your garden. ​Because it may contain pests or diseases.

For seeds: sow them about 1/4 inch deep in the potting mix. Lightly cover with more mix. Keep the soil moist but not waterlogged.

For seedlings: carefully remove them from 5 gallon pot. Transplant them into the prepared pot. Make sure to keep the soil level consistent.

Place the pots in a sunny location. It should receive 6-8 hours of direct sunlight each day. You can use grow lights to provide adequate light if you are growing indoors.

As the seedlings grow, thin them out so that only one strong plant remains in each pot. This will prevent overcrowding and allow the plant to receive enough nutrients and water.

Proper Spacing and Depth

A general rule is to plant one seedling per 5 gallon container or two seedlings in a 10 gallon pot. When planting your seedlings, make sure to cover the stem up to the first set of true leaves. This will encourage a strong root system to develop and help the plant grow taller.

Watering and Maintenance

Watering Schedule

Provide them with consistent moisture to avoid blossom-end rot and cracking of fruits. Keep a regular watering schedule. Preferably once or twice a day depending on the weather conditions. During hotter days, it may be necessary to water more frequently.

Watering Techniques

When watering beefsteak tomatoes in pots, make sure to water at the base of the plant. Avoid wetting the leaves as this can lead to fungal diseases. Using a watering can or drip irrigation system can provide targeted watering.

Water deeply rather than frequently. This encourages deep root growth and strengthens the plants' ability to withstand drought conditions. To check if your plants need watering, stick your finger about an inch into the soil. If it feels dry, it's time to water.

Fertilization Requirements

Fertilize your potted beefsteak tomatoes every two to three weeks. Starting when the plants have established themselves and are actively growing. Avoid over-fertilizing, as this can lead to excessive foliage growth and reduced fruit production.

When fertilizing beefsteak tomato in pot, make sure to water them first and then apply the fertilizer. This will help avoid burning the plants with concentrated fertilizer. Lightly scratch the fertilizer into the top inch of soil, so it can easily reach the roots.

Mulching and Staking

Mulch helps retain moisture in the soil, suppress weeds, and regulate soil temperature. For beefsteak tomatoes in containers, 2-3 inches of organic mulch is recommended. For example, straw or shredded leaves.

Choose a sturdy stake and drive it into the soil near the base of the plant. For example, bamboo or metal. As the plant grows, gently tie it to the stake using garden twine. This will help prevent the branches from breaking under the weight of the tomatoes.

Sunlight and Temperature Requirements

Sunlight Needs

Beefsteak tomatoes require plenty of direct sunlight. The plant should be exposed to the sun’s rays during its peak hours. However, too much direct sunlight can also harm the plants. For example, sunscald or leaf burn. Therefore, monitor the amount of sunlight your beefsteak tomatoes are receiving. Provide shade if necessary.

Managing Temperature

Tomatoes are sensitive to extreme temperatures. This can affect their growth and production. The ideal temperature is between 70°F-80°F. Move the pots to a shaded area during the hottest part of the day. Cover the plants with plastic sheets during cold weather.

Dealing with Pests and Diseases

Common Pests and Diseases

Aphids, whiteflies and spider mites are common pests. These tiny creatures feed on the leaves, stems and fruits. This can cause significant damage to your beefsteak tomatoes.

Another common pest is the tomato hornworm. These large caterpillars can quickly strip a plant of its leaves. They are challenging to spot as they blend in well with the foliage. If left unchecked, they can severely damage or even kill your beefsteak tomatoes.

Diseases such as blight, wilt, and mosaic virus can also affect beefsteak tomatoes. Various fungi, bacteria and viruses can cause these diseases. They are easily transmitted from plant to plant.

Organic and Natural Methods

You can attract beneficial insects to your garden. For example, ladybugs, lacewings, and hoverflies. These insects feed on pests like aphids and whiteflies.

Certain plants can repel pests with their strong scents. For example, marigolds and basil. Planting them alongside your beefsteak tomatoes can help prevent pest infestations.

Organic sprays are effective in controlling pests without harming beneficial insects. For example, neem oil or garlic oil.

Pruning and Training Techniques

Importance of Pruning

Pruning involves removing suckers and lower leaves to promote better airflow and light penetration. This helps prevent diseases and encourages the plant to focus its energy on fruit production.

Beefsteak tomatoes are indeterminate varieties. They will continue to grow and produce fruits until the first frost. Without proper pruning, these plants can become too bushy and crowded. This results in smaller fruits and increased chances of disease.

How to Prune and Train Beefsteak Tomato in Pots?

Remove any suckers as these can compete with the main stem for nutrients. This can lead to reduced fruit production. Next, remove any lower leaves that are touching the soil. Because these can easily pick up diseases and transfer them to the rest of the plant.

As the plant grows taller, use stakes or trellises to support its weight. This can stop plant pots falling over in the wind. This also helps promote better air circulation and light penetration.

Harvesting and Storage

Signs for Harvest

Ripe tomatoes will have a bright and deep red color, with no hints of green. You can gently press it to determine if your tomato is ripe. A ripe tomato will give in slightly when pressed but should not feel too soft or mushy.

Techniques for Picking and Storing Tomatoes

Handle them with care when picking your tomatoes. Use a sharp pair of scissors or shears to cut the stem of the tomato. Instead of pulling it off the plant. This will prevent any damage to the tomato.

You should store tomatoes at room temperature, away from direct sunlight or heat sources. You can also wrap each tomato individually in newspaper. Store them in a basement or pantry for later use. This will slow down the ripening process. You can enjoy your tomatoes for several weeks.
