How to Train Cordon Tomatoes: A Beginner's Guide

Tomatoes are one of the most popular vegetables (or fruits, depending on who you ask) to grow in a home garden. They are relatively easy to cultivate and provide a bountiful harvest. However, training tomatoes can be a bit tricky, especially if you're not familiar with the process. In this article, we'll walk you through the steps to train cordon tomatoes to help ensure a successful crop.

What Are Cordon Tomatoes?

Cordon tomatoes are a type of tomato plant that is trained to grow vertically rather than sprawling along the ground. This method of growing helps conserve space and makes it easier to manage the plants. The plants are trained to grow up a single stem or leader, which is supported by stakes or trellises.

Choosing the Right Tomato Variety

The first step in training cordon tomatoes is selecting the right variety. Look for determinate or indeterminate varieties that are well-suited for vertical growth. Determinate varieties tend to have a more compact growth habit and are often bushy, while indeterminate varieties grow tall and require support.

Some popular cordon tomato varieties include:

• Roma
• San Marzano
• Celebrity
• Beefsteak

Planting Cordon Tomatoes

When planting cordon tomatoes, space them about 1 foot apart. This will help ensure adequate airflow and light penetration. Make sure to plant them in soil that is rich in nutrients and has good drainage.

After planting, prune the leaves from the bottom few inches of the stem. This will help prevent disease and pests from attacking the plant.

Training Cordon Tomatoes

As the cordon tomato plants grow, it's important to train them properly. Use stakes or trellises to support the main stem or leader as it grows upward. Tie the stem to the support every 6 inches or so, being careful not to tie it too tightly.

As the plant grows taller, pinch off any side shoots that develop in the leaf axils. This will help keep the plant focused on growing upward rather than outward.

Once the plant reaches its desired height (usually around 5 to 6 feet), pinch off the top of the stem. This will encourage the plant to focus on producing fruit rather than continuing to grow taller.

Watering and Fertilizing Cordon Tomatoes

Cordon tomatoes require regular watering to ensure they stay healthy and productive. Water deeply once or twice a week, depending on how hot and dry the weather is. Be careful not to overwater as this can lead to root rot.

Fertilize the plants every two weeks with a balanced fertilizer, such as a 10-10-10 ratio. This will provide the necessary nutrients for the plants to produce a bountiful harvest.

Harvesting Cordon Tomatoes

When the tomatoes are ripe, they will be firm to the touch and have a deep, rich color. Gently twist the tomatoes off the vine or use scissors to cut them off. Be careful not to damage the stem or other parts of the plant.

If there are any green tomatoes left when the weather starts to turn cold, you can pick them and ripen them indoors. Store them in a cool, dry place and check them regularly for signs of ripening.
