What is Pinching Out?

When growing tomato plants, pinching out is a common technique used to encourage growth and improve fruit production. Pinching out means removing the tip of a stem or lateral shoot when it reaches a certain height or stage of growth. By removing the growing tip, you create a bushier plant with more lateral shoots, which leads to more flowers and ultimately, more fruit.

When to Pinch Out Tomato Plants

The ideal time to pinch out tomato plants depends on the variety you are growing and the season in which they are planted. For example, if you are growing determinate tomatoes, which only grow to a certain height and stop growing, pinching out is not necessary. However, if you are growing indeterminate tomatoes, which can grow up to several feet tall, pinching out is recommended.

Typically, you should pinch out tomato plants when the plant has grown to around 20-30cm tall and has produced four to six leaves. At this stage, the plant has enough foliage to support new growth and can tolerate the removal of the growing tip.

How to Pinch Out Tomato Plants

To pinch out tomato plants, you will need a pair of clean, sharp scissors or pruning shears. Identify the top of the main stem and locate the first side shoot or lateral branch. This side shoot should be above the second or third leaf. Use your scissors or pruning shears to cut off the top of the plant just above the side shoot.

Pinching out tomato plants can be done every two to three weeks during the growing season, or until you reach the desired size or your growing conditions change. Remember to keep your plants well-fed and watered as this will help encourage new growth and ensure the plant remains healthy.

The Benefits of Pinching Out Tomato Plants

By pinching out tomato plants, you can enjoy several benefits. Firstly, it encourages the plant to grow laterally, which helps to produce more flowers and ultimately, more fruit. Secondly, it can help to prevent the plant from becoming too top-heavy and falling over. Lastly, it can improve the overall health of your tomato plants, as well as improving the flavor and quality of the fruit.

So, whether you are a seasoned gardener or a novice, pinching out tomato plants is a simple and effective technique that can help you produce a healthier, more fruitful harvest. Just remember to pay attention to the variety you are growing and the season in which they are planted, and you'll be rewarded with a bountiful crop of delicious tomatoes.
