How To Prune Tomato Plants – Harvest Tomatoes Earlier By Pruning to a Single Stem
In this video and article, how to prune tomato plants and harvest tomatoes earlier by pruning to a single stem. This technique is especially useful for those with a short growing season, as it allows the plant to focus on producing fruit rather than expanding and growing more vegetation. Pruning to a single stem is one of the best tomato growing tips and tricks.
Understanding the Different Parts of a Tomato Plant
The main stem is the foundation of the tomato plant, and it is from this stem that the branches grow. The lateral grow between the branches and the main step are called suckers, and they are the growth points that the plant uses to expand. To encourage growth in the fruit, it is essential to remove these suckers, so let’s look at how to prune tomato plants.
How To Prune Tomato Plants to a Single Stem
Prune indeterminate tomatoes to a single stem. Indeterminate tomatoes are the vining type and will continue to grow vertically. To prune them to a single stem, you should remove the bottom leaves and the bottom branches. Then remove the suckers between the branches and the main step. This will prevent the plant from expanding and allow it to focus on producing fruit.
On the other hand, determinate tomato plants are also known as bush tomato plants, as they have a more compact and bush-like growth habit and should be left growing bushy. However, pruning the lower branches can help reduce the changes of disease, as this will increase airflow and is typically the part of the plant that touches the soil and stays moist.
Supporting the Tomato Plant
When pruning to a single stem, it is essential to provide support to the main branch. A stake that is at least three feet tall is recommended. As the plant grows, it may be necessary to replace the stake with a bigger one. When supporting the plant, you can wind it up the stake or use a string trellis.
Tomato Planting Density
When pruning to a single stem, you can plant as close as one per square foot. If you are growing determinate tomatoes, you should keep them at about four per square foot. See our square foot gardening chart here.
Final Tips and Tricks for Early Tomato Harvesting
Pruning to a single stem is an effective technique to harvest tomatoes earlier. It allows the plant to focus on producing fruit and prevents it from expanding. Remember to remove the bottom branches and leaves, provide support to the main branch, and plant at the appropriate density.
