Pruning Tomato Plants for a Bountiful Harvest

how to top tomato plants

Learning the art of pruning tomato plants can elevate your gardening game and result in the juiciest tomatoes you’ve ever tasted. Whether you’re growing cherry tomatoes or large heirlooms, in a pot or a garden bed, these pruning tips will help you achieve a bumper crop that will make you feel like a pro.

Why Prune Tomato Plants?

Moisture is the enemy of healthy tomato plants. Any conditions that keep tomato leaves wet can lead to diseases and fungus. By pruning tomato plants, you increase air circulation, reduce moisture build-up, and decrease the risk of diseases.

While some gardeners may not find the need to prune, those who have dealt with tomato diseases and lost their harvest early will understand the value of pruning.

Determinate vs. Indeterminate Tomato Plants

All tomato plants fall into two categories: determinate or indeterminate. Determinate varieties, labeled as dwarf, mini-dwarf, or bush, have a predetermined growth limit. Pruning these varieties will reduce your tomato harvest. On the other hand, most tomato plants are indeterminate, which means they can keep growing and producing as long as they stay healthy. Pruning indeterminate tomato plants ensures their overall health and longevity.

Tools Needed

Pruning tomatoes doesn’t require specialized tools. A simple pair of pruning shears from your garden center will do the trick. In a pinch, scissors can also be used. Just make sure to cut the stems cleanly without damaging the plant.

How to Prune Tomato Plants

It’s best to start pruning tomato plants when they are young, typically around 12 to 15 inches tall. Here’s a step-by-step guide:

1. Pinch Off the First Set of Blossoms

When transplanting your tomatoes, pinch off any blossoms within the first week or so. This may seem counterintuitive, but it allows the plant to focus its energy on developing a strong root system, leading to a better harvest in the long run.

2. Trim Off Anything that Touches the Ground

Remove any branches with leaves touching the ground. These leaves are more susceptible to disease and fungal infections due to moisture accumulation. Trimming them also helps prevent insect damage.

3. Remove the Suckers

Suckers are small shoots that emerge at the junction of the main stem and branches. If left unpruned, they can make the plant bushy, restrict airflow, and promote moisture retention. Locate the suckers and trim them off.

4. Clean Up the Clippings

Dispose of the leaves, stems, and suckers you remove. Only compost healthy clippings, as diseased ones can spread diseases to your plants.

5. Continue Pruning

As your tomato plants grow, continue to remove lower leaves and suckers every few days. When the lower leaves turn yellow, they can be removed. Train your tomatoes to a trellis to maximize space and airflow.

Tomato Pruning Tips

How to Prune Mature Plants

If you haven’t been able to prune your tomato plants when they were young, and they have experienced significant growth, it’s important to be cautious while pruning. Cutting off large stems can leave wounds that are susceptible to infections. Always use sharp garden shears and prune when it’s dry outside, preferably in the morning or evening.

Topping Tomato Plants

Topping tomatoes involves cutting off the top of the plant. While this can stunt the growth, it redirects the plant’s energy towards ripening existing fruit instead of producing more stems and flowers. If your tomato plant is becoming too tall for support or your growing season is coming to an end, topping can be beneficial.

Cloning Suckers

Trimmed suckers can be rooted to create clone plants. Place small healthy suckers in a glass of water until they develop a new root system. Once rooted, they can be planted directly into the ground.

Watch for Fasciated Blossoms

Fasciated blossoms are genetic mutations where multiple blossoms fuse together. While they may result in unique-looking tomatoes, they can cause rot and drain the plant’s energy. Pinching off these fused blossoms will give you a more uniform and useful harvest.
