Before we get our hands dirty, let’s explore the essentials of tomato pruning to set the stage for success.

Which Tomatoes Need Pruning?

Tomato plants fall into two main categories: determinate and indeterminate. Determinate types have a predefined height limit, while indeterminate varieties continue to grow throughout the season.

Only indeterminate tomato plants require pruning. Determinate types, on the other hand, should be left untouched to maximize their fruit production potential.

When in doubt, refer to the plant tag or seed packet description to determine the type of tomato plant in your garden.

Why You Should Prune

Pruning plays a crucial role in enhancing the size and yield of your tomato plants. Indeterminate varieties, with their boundless growth potential, often produce excessive foliage and stems that can overshadow the fruit and impede air circulation.

By selectively pruning stems and leaves, you allow the plant to focus its energy on fruit production. This not only boosts fruit size and quality but also minimizes the risk of fungal or bacterial diseases.

When to Do the Work

Timing is key when it comes to pruning tomato plants. Keep an eye on your plants, and once you notice flower formation, it’s time to break out the pruning shears. This typically occurs between mid-June and mid-July, depending on your location.

After the initial pruning session, follow up every two weeks until your tomatoes reach their mature color. Always prune when the plants are dry to prevent issues like sunburn and disease.

How to Prune Tomato Plants

Before you start pruning, let’s familiarize ourselves with some key terms:

Main stems: Vertical growth supporting lateral branches
Branches: Smaller growth extending from main stems
Suckers: Small growth points between stems and branches

Remove suckers as close to the base as possible to redirect energy to fruit production. Clean your tools between plants to prevent disease spread, and remember not to remove more than a third of foliage at once.

Tips for Pruning:

Use clean scissors or pruners
Pinch off suckers with your fingers
Remove suckers at the plant base
Prune dry plants to prevent issues

What About Determinate Types?

While we advocate for leaving determinate tomato plants unpruned, certain situations warrant intervention. If a branch is damaged or diseased, don’t hesitate to remove it. Additionally, eliminate any fruit clusters that are too close together or lower branches that start turning yellow.

However, avoid extensive pruning of determinate types, as this can hinder their natural growth pattern and reduce yield.
