Introduction

Hydroponic tomato farming has rapidly gained popularity due to its numerous advantages such as faster plant growth and higher yield. Pruning is an essential technique that helps to enhance the growth of hydroponic tomato plants, increase the yield, and improve fruit quality. In this article, we will discuss how to properly prune hydroponic tomato plants to achieve maximum productivity.

Why pruning is important?

Pruning is crucial for hydroponic tomato plants because it helps to accomplish the following:

Promotes air circulation: Pruning helps in opening up the dense canopy of the plants, promoting airflow, and reducing the proliferation of pests and diseases.

Controls plant size: Hydroponic tomato plants can grow up to huge sizes that might be difficult to manage. Pruning controls the plant's size by reducing its height and width.

Enhances fruit quality: Pruning helps to concentrate the plant's energy on fruit production leading to high-quality tomatoes.

Increases yield: Proper pruning improves the plant's productivity by providing optimal growing conditions for the plant.

When to prune hydroponic tomato plants?

Pruning should be done throughout the growing process regularly. However, the specific timing will depend on the kind of pruning you wish to do.

Formative pruning: This should be done when the plant has developed two sets of leaves. During this time, remove the lateral shoots that grow from the main stem.

Maintenance pruning: This pruning is done when the plant is fully grown, and it involves removing leaves that yellow or wilt constantly.

Fruit-bearing pruning: This is done when the flowers have bloomed to encourage fruit growth. Mostly, it entails removing the leaves that get in the way of light and airflow.

How to prune hydroponic tomato plants?

The pruning technique for hydroponic tomato plants is determined by the growing system, plant variety, and stage. Below are the ways in which you can prune hydroponic tomato plants;

Staking: Staking helps the plant to grow supported and prevents toppling. You need to anchor a stake to the plant's base then tie the stem to the stake. Remember to remove the suckers that grow from the joints where the branches meet.

Thinning: Thinning refers to removing excess foliage on the plant. Mostly, you should remove foliage to a third of the plant so that light penetrates through to the fruits below. Do this by cutting off the branches with sharp garden shears.

Pinching: Pinching entails removing a branch or shoot by pinching it out with your fingertips. Pinching encourages a bushier plant by stopping growth on the pinched branches and redirecting nutrients to the remaining parts of the plant.

Tips for pruning hydroponic tomato plants

The following tips will help you in pruning hydroponic tomato plants effectively;

Use sharp garden shears when pruning

Remove only 20-25% of the foliage at a time to prevent the plant from going into shock.

Sterilize the pruning tool between sessions to prevent the spread of bacteria or fungi that can affect the plant.

Always prune in the morning or evening when the plant is stronger to reduce damage.

Make clean and straight cuts below the node or joint to avoid damaging the plant.

Conclusion

Pruning is essential for hydroponic tomato farming as it helps to manage size, enhance fruit quality, maximize yield, and control pest and disease proliferation. Remember to follow the appropriate pruning guidelines for each stage of the plant's growth and use sharp tools while promoting sterile conditions. Follow these tips, and you will have healthy, bountiful, and productive hydroponic tomato plants.
