What Is a Sucker on a Tomato Plant and How Does It Impact Growth?

What Is a Sucker on a Tomato Plant?

A sucker on a tomato plant is a secondary stem that grows in the joint where a leaf meets the stem.

These suckers can either be allowed to grow or removed, depending on personal preference.

Keeping suckers on the plant may result in better tasting tomatoes as they contribute to plant growth, while removing suckers may lead to fewer but larger-sized fruits.

Determinate tomato plants can benefit from leaving suckers to grow, while indeterminate plants may become more susceptible to tomato diseases if suckers are not removed.

Key Points:

  • Suckers on a tomato plant are secondary stems that grow where a leaf meets the stem.
  • Suckers can be left to grow or removed based on personal preference.
  • Keeping suckers can improve the taste of tomatoes and contribute to plant growth.
  • Removing suckers may result in fewer but larger-sized fruits.
  • Determinate tomato plants benefit from leaving suckers to grow.
  • Indeterminate plants may be more vulnerable to tomato diseases if suckers are not removed.

Did You Know?

1. Suckers on tomato plants are not actually a type of pest or disease, but rather stem growth that sprouts from the leaf axils.
2. Tomato plant suckers can divert energy and nutrients away from the main stem and fruits, resulting in reduced overall yield if not properly pruned.
3. Some gardeners prefer to remove tomato suckers to focus the plant’s energy on fruit production, while others allow them to grow and form additional branches, creating a bushier plant.
4. Interestingly, tomato plant suckers can be easily propagated by simply placing them in water until they develop roots, after which they can be replanted and grown into new tomato plants.
5. While some people remove all suckers, certain heirloom tomato varieties actually produce sweeter and more flavorful fruit if the suckers are left to grow, as they contribute to increased foliage and shading.

Tomato Suckers: Definition And Types Of Tomato Plants

Tomato suckers, also known as lateral shoots or axillary buds, are secondary stems that form at the joint between a leaf and the main stem of a tomato plant. These suckers have the potential to grow into fully-developed branches with their own sets of leaves, flowers, and fruits.

There are two main types of tomato plants: determinate (bush) and indeterminate (vining). Determinate tomato plants are compact and typically grow to a maximum height of around 3 to 4 feet. They stop their upward growth once they reach this height. Determinate tomato plants also produce their fruit within a relatively short period of time.

Indeterminate tomato plants, on the other hand, are more vigorous. They continue to grow until they are killed by frost. These plants produce flowers and fruits continuously throughout the growing season.

Importance Of Tomato Suckers In Plant Growth And Fruit Production

The decision to allow tomato suckers to grow or to remove them depends on personal preference and the desired outcome. Suckers contribute to overall plant growth and can potentially result in better tasting tomatoes. By allowing suckers to grow, the plant gains additional leaves, stems, and roots, which can enhance its ability to absorb nutrients and produce energy through photosynthesis. This increased growth can lead to more robust plants and potentially sweeter, juicier tomatoes.

However, removing suckers may also have its benefits. By focusing the plant’s energy on fewer branches, the fruits that do develop may grow larger in size. This can be particularly desirable for gardeners who prefer larger-sized tomatoes or those who prioritize maximizing yield per fruit. Additionally, removing suckers allows for better air circulation and light penetration throughout the plant, reducing the risk of diseases caused by excessive moisture and shade.

It is worth noting that personal experimentation has not shown a significant difference in fruit size or flavor when removing suckers. This suggests that the impact of pruning suckers may vary depending on factors such as tomato variety, growing conditions, and individual plant vigor.

  • Allowing suckers to grow can result in overall plant growth and potentially better tasting tomatoes.
  • Removing suckers can help redirect the plant’s energy towards fewer branches, resulting in larger fruit size.
  • Better air circulation and light penetration are among the benefits of removing suckers.
  • Pruning suckers may have varying impacts depending on factors such as tomato variety, growing conditions, and plant vigor.

Pruning Tomato Suckers: Personal Preferences And Effects On Fruit Size And Flavor

Pruning tomato suckers is an integral part of tomato plant maintenance and can greatly impact fruit size and flavor. Depending on the type of tomato plant and personal preferences, different approaches to pruning suckers are recommended.

With determinate tomato plants, allowing suckers to grow can be beneficial. Since these plants have a predetermined height and fruiting period, leaving suckers to develop can contribute to overall plant vigor and ability to produce fruits. The additional growth provided by the suckers can support more substantial fruiting, resulting in higher yields.

On the other hand, indeterminate tomato plants may become more susceptible to tomato diseases if suckers are not systematically removed. The continuous growth of these plants means that they will continue to produce new suckers throughout the growing season. Without proper pruning, the dense foliage can create a conducive environment for diseases, as air circulation and sunlight penetration become limited. Pruning suckers in indeterminate tomatoes helps maintain an open canopy, reducing the risk of fungal growth and increasing the plant’s overall health.

Different Approaches To Tomato Suckers Depending On Plant Support System

The support system for tomato plants greatly impacts how we manage suckers. One effective method involves growing tomatoes on sturdy one by two by seven-foot wood stakes and twine in a polytunnel. This setup provides stability and allows for effective sucker management.

When it comes to single-staked tomato plants, especially large fruited varieties, it is recommended to pinch out most suckers, leaving only three to four. This approach helps channel the plant’s energy towards a limited number of branches, resulting in larger fruits and higher productivity. However, when growing cherry tomatoes on stakes, it is preferred to allow suckers to develop as it leads to a high fruit yield. To accommodate the vigorous growth resulting from maximum sucker development, it is advised to space cherry tomato plants three feet apart.

On the other hand, if you are using a trellis or double stakes, training one or two suckers alongside the central stem to have two to three main stems is preferable. This method provides better support and increases fruit production.

For those using tall wire cages, it is recommended to allow three to four suckers to develop for large fruited tomato plants, as it increases overall production. However, for cherry tomatoes, maximum sucker development is still recommended.

In the case of growing tomatoes in polytunnels, the preferred method involves using jute twine. Each seedling should have twine loosely tied to its base, and the main stem should be wound around it. For large fruited tomato plants, it is advised to leave three to four suckers to develop. However, for cherry tomatoes, it is advisable to pinch out half of the suckers to control their vigorous growth.

Additional Tips For Growing Productive And Beautiful Tomato Plants

In addition to managing tomato suckers, there are several other tips to grow productive and beautiful tomato plants.

  • One aspect is pruning the bottom leaves of the plants. By removing the lower leaves, the risk of spreading soil-borne diseases is minimized, as the leaves come into contact with the ground.

  • Another important technique mentioned by the author is topping the plants in late summer or when they grow past the top of their stakes. This involves cutting off the top of the plant above the last fruit cluster that still has time to mature before fall. Topping the plants helps redirect the plant’s energy into the remaining fruits, ensuring optimal ripening and reducing the risk of overgrowth.

  • The article also discusses the importance of choosing the right support system, choosing the best fertilizer, and knowing when to pick the fruits for optimum flavor and ripeness.

Frequently Asked Questions

What are the shoots on tomatoes?

Tomato shoots, also known as side shoots, emerge between the main stem of the plant and an established leaf stem. These shoots are the plant’s attempt to develop additional stems and branches. They can be seen as small offshoots that divert energy away from the central stem, potentially affecting the overall growth and fruit production. Prompt removal of these side shoots is often recommended to promote better airflow, light penetration, and fruit development on the main stem.

What part of tomato plant to prune?

When it comes to pruning tomato plants, the focus should mainly be on removing the suckers. Suckers are shoots that grow in the axils where side branches meet the stem. By regularly inspecting the plant and promptly removing these suckers while they are small, either by pinching them off or snipping them with pruners, you can ensure that the indeterminate tomato plant stays more manageable and produces a higher yield of fruit.

What is the stalk of a tomato called?

The stem of a tomato plant where the leaflets attach to the central stem is called the petiolule. This small but essential structure acts as a connection point between the main stem and the individual leaflets, facilitating the plant’s overall growth and development. By understanding the specific terminology of tomato plant anatomy, we gain a deeper appreciation for the intricate details that contribute to the plant’s overall structure and function.

Should all tomato plants have side shoots removed?

Removing side shoots from tomato plants is a practice that can vary depending on the desired outcome. While it is commonly done to promote the growth of one single stem, there are situations where allowing some side shoots to remain can be beneficial. For instance, if a gardener desires a bushier tomato plant with more fruits, allowing selected side shoots to develop can result in increased yield and more robust overall growth. However, for those aiming to maximize fruit size or maintain a neat and organized garden bed, removing all side shoots may be the most suitable approach. Ultimately, the decision to remove or retain side shoots should be based on individual preferences and specific goals for each tomato plant.
