Pruning a tomato plant is an important step in ensuring a healthy and productive plant. The main purpose of pruning is to remove any diseased, damaged, or dead leaves or stems. This helps the plant to focus its energy on producing fruit, rather than on unnecessary growth. Pruning also allows more air and sunlight to reach the fruit, preventing fungal diseases and encouraging ripening.

Tomato plants can be pruned in one of two ways: by pinching off the tips of the main stem, or by cutting off entire side branches. Pinching is the most common method of pruning, and is typically done when the plant is young and still growing vigorously. This encourages the plant to branch out, making it bushier and more productive. To pinch off the tips of the main stem, simply use your fingers to break off the desired length of stem.

Cutting off entire side branches (also called “suckers”) is typically done when the plant is older and has reached its desired size. This helps to prevent the plant from spreading too wide and becoming sparse. It also keeps the fruit from being shaded by leaves and reduces competition for resources between fruit-bearing branches and non-fruit-bearing ones. To cut off a side branch, use a sharp pair of pruning shears to make a clean cut just above where the branch meets the main stem.

What You’ll Need

-Pruning shears
-Rubber band or string
-Stakes (optional)

Pruning shears are the tool of choice for pruning most tomato plants. You can find them at your local hardware or gardening store. They come in different sizes, so choose a pair that feels comfortable in your hand.

You’ll also need a rubber band or some string to tie the plant to the stake. If you’re using stakes, choose ones that are at least 6 feet (1.8 m) tall so the plant has room to grow.

Step-by-Step Instructions

This how-to guide will show you the proper way to prune a tomato plant. Pruning tomatoes is important for two reasons: it helps the plant produce more fruit, and it helps prevent disease.

Before you prune your tomato plant, you’ll need a sharp pair of pruning shears. Clean the shears with rubbing alcohol before and after use.

To prune your tomato plant, follow these steps:

1. Cut off any dead or diseased leaves. Dead leaves can harbor disease, so it’s important to remove them. If you see any leaves that are discolored or have spots, cut them off as well.

2. Trim away any suckers that are growing from the stem of the plant. Suckers are small shoots that grow in the axils (the area where the leaf meets the stem). Suckers take energy away from fruit production, so it’s best to remove them.

3. Cut off any leaves that are touching the ground. Leaves that touch the ground are more likely to develop disease, so it’s best to remove them.

4. Thin out crowded branches. If branches are growing too close together, thin them out so that there is about 6 inches between each branch. This will improve air circulation and help prevent disease.

Tips and Tricks

Pruning a tomato plant helps to increase airflow and allows the plant to focus its energy on producing fruit. In this article, we’ll give you some tips and tricks on how to prune a tomato plant for the best results.

Before you start pruning, it’s important to understand that there are two types of tomato plants – determinate and indeterminate. Determinate plants produce fruit all at once and then stop growing, while indeterminate plants produce fruit continuously throughout the growing season.

Pruning a determinate plant is fairly straightforward – you simply need to remove any suckers (side shoots) that appear below the first flower cluster. Suckers compete with the main stem for nutrients and can reduce the overall yield of the plant.

To prune an indeterminate plant, you need to remove suckers as they appear, as well as any leaves that are blocking sunlight from reaching the fruit. It’s also a good idea to remove any branches that are weak or damaged.


Pruning tomato plants is an important step in ensuring a bountiful harvest. Taller tomato plants need to be staked or caged, and all varieties will benefit from having the lower leaves removed. You should also remove any suckers that grow in the crotch between the main stem and side branches. With a little care, your tomato plants will produce plenty of delicious fruit all season long!
