How and When to Prune Your Tomato Plants | 2023 Tomato Pruning Guide


Tomatoes are a popular and versatile vegetable to grow in your garden. To ensure healthy and productive plants, it’s important to know how and when to prune them. Pruning helps improve air circulation, reduce disease risks, and promote better fruit production. In this article, we will guide you through the process of pruning your tomato plants in the year 2023.

Why Prune Tomato Plants?

Pruning tomato plants has several benefits. Firstly, it helps increase air circulation around the plant, reducing the chances of fungal diseases like blight. Pruning also allows more sunlight to reach the lower parts of the plant, promoting better fruit ripening. Additionally, removing excess foliage can help redirect the plant’s energy towards fruit production, resulting in larger and tastier tomatoes.

When to Start Pruning

It’s important to wait until your tomato plants have grown to a certain size before pruning. Typically, you should start pruning when the plants have developed 6-8 true leaves and are about 12-18 inches tall. This usually occurs around 4-6 weeks after transplanting seedlings into the garden. Pruning too early can stunt the growth of your plants, so it’s essential to be patient.

How to Prune Tomato Plants

Step 1: Remove Suckers

Suckers are the small shoots that grow in the leaf axils of tomato plants. They can divert energy away from the main stem and reduce fruit production. To prune suckers, simply pinch them off with your fingers when they are small (around 1-2 inches long). Be careful not to damage the main stem.

Step 2: Remove Lower Leaves

As your tomato plants grow, it’s beneficial to remove the lower leaves that touch or are close to the ground. These leaves are more prone to diseases and pests. Use clean pruning shears to cut off the lower leaves, leaving a few inches of stem exposed. This will help prevent soil-borne diseases from splashing onto the foliage.

Step 3: Thin Out Foliage

Tomato plants can become dense with foliage, especially if left unpruned. To improve air circulation and reduce disease risks, thin out the foliage by selectively removing some of the leaves. Start by removing any yellow or diseased leaves. Then, remove a few leaves from the middle and lower sections of the plant to create space between branches.


Pruning your tomato plants is a crucial step in maintaining their health and productivity. By following the proper pruning techniques, you can improve air circulation, reduce disease risks, and promote better fruit production. Remember to start pruning when the plants are of the right size, remove suckers and lower leaves, and thin out the foliage. With these tips, you’ll be on your way to growing healthy and abundant tomatoes in the year 2023!
