How to Prune Tomato Plants Correctly

Tomato plants need pruning to ensure they grow tall and healthy, and produce better fruit. However, pruning incorrectly can harm the plant if you cut too many leaves or make improper cuts. In this article, you will learn how to correctly prune tomato plants to promote growth, a bigger fruit yield, and a healthier plant overall.

When to Prune Tomato Plants

You should start pruning tomato plants when they reach 12 to 18 inches tall, and have developed several branches. Knowing when to prune can be tricky, but as a general rule, you should prune tomato plants when they have grown to half their expected final height. Make sure not to prune the plant excessively or too often, as this can stress the plant and affect fruit production.

How to Prune Tomato Plants

Step 1: Identify the Suckers. You can find suckers by looking for new growth in the joint between the main stem and the branches. Suckers grow quickly and, if left unchecked, can take valuable nutrients from the main stem, reducing your plant’s overall production. Remove suckers when they are small.

Step 2: Trim the Branches. Remove the bottom 6 to 12 inches of branches on your tomato plants. Trimming the leaves at the bottom of your plant can help promote good air circulation and prevent the spread of disease

Step 3: Identify the Good Stems. The best stems are the ones with sturdy, thick branches and big, healthy leaves. These stems are the ones that will produce the most fruit, so it's important to leave them intact.

Step 4: Pinch off the Tops. Pinching off the tops of your tomato plants can encourage the plant to grow more side shoots, which can lead to more fruit. Simply pinch off the growing tip of your plant when it grows to your desired height.

Conclusion

Pruning is an important step in ensuring your tomato plants grow healthy and strong, and produce plenty of fruit. Remember to prune only when necessary and not over-prune your plants. If you follow these tips, your tomato plants will thrive, and you’ll be rewarded with a bountiful harvest.
