Pruning tomato plants is a vital technique to boost their productivity and growth. It is used for removing suckers, but trimming tomato plants promotes growth of the plant.
However, the number of times you should prune tomato plants for a massive harvest depends on several factors. Pruning helps to promote fruit development, increase air circulation, and prevent disease.
In general, tomato plants should be pruned at least once to remove the lower leaves and suckers. If the plant gets too bushy, you may need to prune it, but too much pruning can hurt the plant’s ability to produce.
The frequency of pruning should be based on the specific growth habits of the tomato plant, the desired size of the harvest, and the gardener’s experience level.
In this article, I will tell you why pruning is necessary and pruning of tomato plants for huge harvests.
Is Pruning or trimming Necessary For Tomato Plants?
Trimming tomato plants is not absolutely necessary, but it can be beneficial in promoting plant growth, fruit development, and disease prevention.
When you prune tomato plants, you remove unwanted growth, such as suckers and lower leaves, which can help the plant focus its energy on producing fruit. Pruning can also improve air circulation around the plant, reducing the risk of disease, and make it easier to manage the plant’s size and shape.
But some types of tomatoes may not need to be pruned, especially determinate types that grow in a more compact way. So, the decision to prune tomato plants should depend on the specific variety, growth habits, and the gardener’s preferences and goals.
Pruning For Determinate Vs Indeterminate Tomato Plants
There are two types of tomato varieties;
- Determinate tomato variety
- Indeterminate tomato variety
Pruning For Determinate Varieties
Pruning is not essential for determinate tomato varieties because they have a more compact growth habit and tend to produce a more concentrated harvest. Pruning can help determinate tomato varieties produce a more abundant and high-quality harvest.
These varieties typically grow to a predetermined size and set most of their fruit at one time, making it crucial to manage the plant’s growth and support the developing fruit.
Pruning determinate tomato plants can help to remove any unwanted growth, such as suckers and lower leaves, which can take away from the plant’s energy and reduce the size and quality of the fruit.
Pruning For Indeterminate Varieties
Pruning is particularly important for indeterminate tomato varieties because these plants can grow quite large and bushy, producing many branches, leaves, and suckers. Without pruning, the plant can become overcrowded, which can lead to poor air circulation and increased risk of disease.
By removing the lower leaves and suckers, you can help the plant direct more energy into producing fruit, rather than foliage. Pruning also helps the plant focus its resources on the main stem and larger, healthier branches, which can lead to bigger, more robust tomatoes.
Pruning can help manage the size and shape of the plant, making it easier to support with stakes or cages and promote healthier growth, increase yield, and make them easier to manage in the garden.

5 Times You Should Prune Indeterminate Tomatoes
Indeterminate tomato varieties are a type of tomato plant that continues to grow and produce fruit throughout the growing season until the first frost. These are known for producing flavorful fruit and grow at the end of the season.
Unlike determinate tomato varieties, which grow to a certain height and then stop growing, indeterminate tomato varieties can grow quite tall and require staking or trellising for support.
However, to achieve the best results with indeterminate tomato plants, proper care and pruning techniques are essential.
1. Pruning Suckers
To prune a sucker in indeterminate tomato varieties, follow these steps:
- Identify the sucker: Look for small shoots that grow between the stem and a leaf branch. These are the suckers that you want to prune.
- Determine the size of the sucker: Prune suckers when they are small and easy to remove. If the sucker is too big, it can leave a large wound on the stem, which can make the plant more susceptible to disease.
- Use your fingers or a sharp knife: Carefully remove the sucker by using your nfingers to pinch it off or a sharp knife to make a clean cut. It’s important to avoid damaging the stem or other branches while pruning.
- Continue to monitor the plant and prune any new suckers that appear.
- Remember that removing too many suckers can reduce the overall yield, so it’s important to strike a balance between removing enough suckers to promote fruit production and leaving enough to maintain plant health.
2. Remove Damaged Branches
To remove damaged branches of indeterminate tomato varieties, you will need a pair of clean and sharp pruning shears.
- The first step is to identify the damaged branch.
- Look for any signs of pest infestation, disease, or physical damage, such as splitting or cracking.
- Once you have identified the damaged branch, make a clean cut just above the damaged area with the pruning shears.
- Be sure to sterilize the pruning shears between each cut to prevent the spread of disease.
- After you cut off the damaged branch, keep a close eye on the plant for signs of more damage or disease.
It’s best to remove damaged branches selectively and gradually over time to minimize stress on the plant.
3. Pruning for Shape and Size
For indeterminate tomato varieties, pruning for shape and size means cutting off certain stems and branches to control the plant’s overall growth and look.
This technique can help prevent the plant from becoming too large or sprawling, making it easier to manage and harvest. To prune for shape and size;
- Start by removing any damaged or diseased stems, followed by any suckers that grow in between the main stem and a leaf branch.
- Next, remove any branches that grow too close together or cross over each other, as these can create a tangled mess of foliage that restricts air flow and promotes disease..
- Finally, prune the top of the plant to control its height, leaving a few leaves at the top to encourage continued growth.
That’s how you can do proper pruning for shape and size and promote healthier growth.
4. Pruning for Airflow
For airflow, indeterminate tomato varieties need to have their lower leaves cut off, their branches thinned out, dead or sick branches cut off, and extra leaves taken off.
This method makes it easier for air to flow around tomato plants and stops diseases from spreading. It’s important to use clean and sharp pruning shears and to leave some foliage on the plant to promote photosynthesis and provide shade for the fruit.
Pruning for airflow should be done regularly throughout the growing season to promote healthy growth and higher yields in indeterminate tomato varieties.
5. Trim Or Stake Low-Hanging Branches
Trimming or staking low-hanging branches is an important pruning technique for indeterminate tomato plants.
Pathogens that cause diseases can get into the plant through low-hanging branches that touch the ground. They can also reduce the amount of sunlight and airflow around the plant, leading to less healthy growth and smaller yields.
To trim low-hanging branches, use clean and sharp pruning shears to make a clean cut just above the leaf node. You can stake the branches to lift them off the ground and promote better air circulation.
The decision to trim or stake low-hanging branches depends on the specific tomato variety and its growth habits.

3 Times You Should Prune Determinate Tomatoes
Determinate tomato varieties are a type of tomato plant that has a predetermined size and growth habit. Determinate tomato plants grow to a specific size and produce all of their fruit within a short period of time.
These plants are often smaller and more compact, making them a good choice for gardeners with limited space. The hardiness of determinate tomato plants makes them a popular choice for canning and preserving.
1. Remove Suckers Below The First Flower Bud
Removing suckers below the first flower bud is a pruning technique that involves removing small shoots that grow between the stem and a leaf branch on indeterminate tomato plants.
This can help the plant put its energy into making fruit instead of leaves, which will make the tomatoes bigger and healthier.
Some gardeners prefer to leave some suckers on the plant to increase the overall yield, while others prefer to remove all suckers to maximize the size and quality of the fruit. Ultimately, the decision to remove suckers below the first flower bud should be based on the individual plant’s needs and the gardener’s goals.
2. Trim Leaves Hitting The Soil
Trimming leaves that touch the soil is an important pruning technique for tomato plants because it prevents soil-borne diseases from infecting the plant and promotes better air circulation. To trim these leaves, use clean, sharp scissors to snip the leaf stem near the base of the plant.
When tomato leaves touch the ground, they can create a pathway for diseases to spread and reduce the plant’s health and productivity.
However, it’s important not to trim too many leaves, as this can reduce the plant’s ability to produce energy through photosynthesis.
3. Remove Damaged Stems
Removing damaged stems is an important trimming technique to keep tomato plants healthy and productive. Damaged stems can be caused by pests, disease, or physical damage, and they can restrict the flow of nutrients and water throughout the plant.
If left untreated, damaged stems can weaken the plant, reduce its yield, and even kill it.
To remove a damaged stem, use clean and sharp pruning shears to make a clean cut just above the damaged area.
To stop the spread of disease, it’s important to clean the pruning shears after each cut. After removing a damaged stem, monitor the plant closely for any signs of additional damage or disease, and take appropriate action if necessary.
When To Prune Tomato Plants?
The timing of pruning tomato plants depends on the growth stage of the plant and the specific pruning technique you plan to use. The first pruning should be done when the plant is about 12–18 inches tall, and this involves removing the lower leaves that are close to the ground.
By taking off these leaves, you can keep soil-borne diseases from infecting the plant and improve air flow. It’s important to prune suckers regularly to prevent them from growing too large and competing with the main stem for nutrients.
If you plan to do heavy pruning, wait until the plant has set some fruit and has reached its desired height before you begin. This will allow the plant to focus on fruit production before it starts redirecting energy towards new growth.
Avoid pruning in the hottest part of the day as it increases the plant’s stress level, so it’s best to prune in the morning or evening when temperatures are cooler.
Conclusion
Pruning or trimming is an important way to help tomato plants grow well and produce more fruit, especially indeterminate varieties.
By removing suckers, trimming low-hanging branches, and removing damaged stems, tomato plants can focus their energy on producing fruit instead of foliage. Pruning can also promote better air circulation and reduce the risk of soil-borne diseases.
