Pruning Techniques to Keep Tomato Plants Short

When it comes to growing tomatoes, many gardeners prefer to keep their plants short and compact. Short tomato plants are easier to manage, require less staking or trellising, and are generally more productive. There are various techniques you can employ to keep your tomato plants short while still ensuring a bountiful harvest. In this article, we will cover some effective methods of pruning and training tomato plants to achieve optimal height and productivity.

1. Pinching Off Suckers

One of the most common techniques for keeping tomato plants short is by pinching off suckers. Suckers are the small shoots that develop in the leaf axils, or where the leaves meet the main stem. These suckers can grow into new branches, causing the plant to become bushier and taller. By regularly pinching off these suckers, you can redirect the plant's energy towards fruit production and limit its height.

To pinch off suckers, use your fingers or a sharp, clean pair of pruning shears. When the suckers are small (less than 2 inches), simply pinch them off with your fingers, making sure to remove the entire sucker from its base. For larger suckers, especially those with flower buds, use pruning shears to carefully cut them off just above the point of attachment to the main stem. Be careful not to damage the main stem or any nearby branches.

It's important to note that not all tomato varieties require extensive sucker removal. Determinate varieties, which naturally have a more compact growth habit, may not need as much pruning. Indeterminate varieties, on the other hand, benefit greatly from regular sucker removal to keep them manageable in size.

Pros of Pinching Off Suckers

  • Controls the plant's height and size.
  • Promotes better air circulation, reducing the risk of diseases.
  • Redirects the plant's energy towards fruit production.
  • Easier to manage and harvest.

Cons of Pinching Off Suckers

  • May slightly reduce overall yield.
  • Requires regular monitoring and pruning.

2. Training Techniques: Staking and Caging

Another effective method of keeping tomato plants short is through training techniques, such as staking and caging. Training your tomato plants helps support their weight and prevents sprawling, which can lead to height and space issues. Two commonly used training methods for tomato plants are staking and caging.


Staking involves using a sturdy support structure, such as stakes or trellises, to provide vertical support for the tomato plant. This method keeps the plants upright, preventing them from sprawling on the ground or growing excessively tall. Staking also facilitates better air circulation and sunlight exposure, reducing the risk of diseases.

To stake tomato plants, insert sturdy stakes into the ground near the base of each plant, ensuring they are deep enough to provide adequate support. As the plants grow, gently tie them to the stakes using soft plant ties, twine, or strips of cloth. Make sure the ties are not too tight to allow for some flexibility and growth. Regularly adjust the ties as the plants continue to grow to prevent constriction.


Caging is another effective training technique for keeping tomato plants short and well-supported. Tomato cages are typically made of sturdy wire mesh or metal and provide a compact growing space for the plants. Cages offer excellent support, prevent sprawling, and allow for good air circulation and light penetration.

To cage tomato plants, place the cages around each plant after transplanting. Gently guide the main stem through the openings in the cage, ensuring that it remains centered. As the plant grows, continue to tuck any large branches or suckers inside the cage to maintain a compact structure. Caging is particularly beneficial for indeterminate tomato varieties that continue to grow and produce fruits throughout the season.

Pros of Training Techniques: Staking and Caging

  • Keeps plants upright and prevents sprawling.
  • Improves air circulation and sunlight exposure.
  • Reduces the risk of diseases.
  • Allows for easier maintenance and harvesting.

Cons of Training Techniques: Staking and Caging

  • Requires additional materials and setup.
  • May limit space for growing multiple plants.

3. Pruning Techniques: Topping and Trimming

Pruning techniques such as topping and trimming are useful for managing the height and size of tomato plants. Topping involves the removal of the central growing tip of the main stem or the first flower cluster, redirecting the plant's growth energy to the side branches and preventing excessive upward growth.

To top tomato plants, wait until they have reached the desired height, usually around 3 to 4 feet, and have multiple side branches. Using clean pruning shears, make a clean cut just above a set of healthy leaves or above the first flower cluster. This will stimulate the growth of the side branches and limit the height of the plant.

Trimming is another pruning technique that involves removing the lower, non-productive leaves from the tomato plant. By doing so, you promote air circulation, reduce the risk of diseases, and ensure that the plant's energy is directed towards fruit development rather than maintaining unnecessary foliage. Trim the lower leaves carefully, making sure not to remove too many at once to avoid stressing the plant.

Pros of Pruning Techniques: Topping and Trimming

  • Controls the height and size of the plant.
  • Promotes better air circulation, reducing the risk of diseases.
  • Redirects the plant's energy towards fruit production.
  • Improves access to sunlight and eases harvesting.

Cons of Pruning Techniques: Topping and Trimming

  • Requires careful pruning to avoid damage to the plant.
  • May slightly reduce overall yield.

4. Fertilizing and Managing Plant Nutrition

Proper fertilization and managing plant nutrition can play a significant role in controlling the height and growth of tomato plants. Excessive nitrogen in the soil can result in vigorous vegetative growth and taller plants. To prevent excessive vertical growth, it is important to provide balanced nutrition for your tomato plants.

Before planting your tomatoes, amend the soil with well-rotted compost or organic matter to provide essential nutrients. During the growing season, use a balanced fertilizer with equal or slightly higher phosphorus and potassium levels compared to nitrogen. Avoid high-nitrogen fertilizers, as they can encourage excessive foliage growth.

In addition to proper fertilization, regular monitoring of soil moisture is crucial. Overwatering can lead to rapid growth, while underwatering can cause stress and a reduction in growth rate. Maintain consistent soil moisture by watering deeply but infrequently, allowing the soil to dry out slightly between watering sessions.

Pros of Fertilizing and Managing Plant Nutrition

  • Helps regulate plant growth and size.
  • Provides essential nutrients for plant development.
  • Promotes balanced vegetative growth and fruit production.

Cons of Fertilizing and Managing Plant Nutrition

  • Requires monitoring and proper application of fertilizers.

Using Dwarf Tomato Varieties

Another approach to keeping tomato plants short is by choosing dwarf or compact varieties. Dwarf tomato plants are bred specifically to have a shorter height without compromising fruit production. These varieties are compact in size, making them perfect for small gardens, containers, or areas with limited space.

There are numerous dwarf tomato varieties available, offering a wide range of colors, flavors, and sizes. Some popular dwarf varieties include 'Tom Thumb,' 'Patio Princess,' 'Celebrity Dwarf,' and 'Tiny Tim.' These varieties typically reach a maximum height of around 2 to 4 feet, making them ideal for people who want to grow tomatoes in containers or smaller garden spaces.

When growing dwarf tomato varieties, regular garden maintenance practices such as watering and fertilizing still apply. However, these plants may require less pruning and training due to their natural compact growth habit.

By utilizing pruning techniques, training methods, and proper plant nutrition, you can successfully keep tomato plants short while maximizing their productivity. Whether you prefer pinching off suckers, utilizing staking or caging, pruning the plants, or opting for dwarf tomato varieties, there are various strategies to achieve your desired plant height and size. Choose the methods that suit your gardening style and enjoy a bountiful harvest of delicious tomatoes!
