Tomato Suckers

Tomato Suckers: A Comprehensive Guide for Gardeners

Are you a gardening enthusiast? If so, you’ve probably heard of tomato suckers. These pesky little shoots can be both a blessing and a curse for your tomato plants. But don’t worry, we’ve got you covered! In this comprehensive guide, we’ll dive deep into what tomato suckers are, how to identify them, and whether or not you should remove them. Now that you have your gardening gloves on, let’s begin!

What Are Tomato Suckers?

Tomato suckers are the new growth that appears in the joint between the main stem and a leaf stem of your tomato plant. These suckers can grow into full-fledged branches, complete with leaves and even fruit. While this might sound great, there’s a bit more to the story.

Why Do Tomato Suckers Form?

Tomato plants are naturally vigorous growers. They’re programmed to spread out and produce as much fruit as possible. Suckers are part of this growth strategy. They help the plant produce more foliage and, potentially, more fruit. However, more isn’t always better.

Identifying Tomato Suckers

So, how do you spot these suckers? Look at the V-shaped area where a leaf stem meets the main stem. You’ll often see a tiny shoot starting to grow there. These are the suckers. If left unchecked, they can grow quite large and compete with the main plant for nutrients and sunlight.

Should You Remove Tomato Suckers?

Ah, the million-dollar question! Should you remove tomato suckers or let them grow? The response is based on your gardening objectives.

Benefits of Removing Suckers

  1. Better Airflow: Removing suckers can improve air circulation around your plant, reducing the risk of diseases like blight.
  2. More Energy for Fruit: By removing suckers, you’re directing the plant’s energy towards producing larger, healthier fruit rather than more foliage.
  3. Easier Maintenance: A well-pruned plant is easier to care for. It’s simpler to stake or cage and makes harvesting a breeze.

Benefits of Keeping Suckers

  1. More Fruit: Letting suckers grow can lead to more tomatoes. If quantity is your goal, this might be the way to go.
  2. Larger Plant: A bushier plant can provide more shade to its fruit, protecting them from sunscald.
  3. Experimentation: Some gardeners like to experiment by letting some plants grow naturally and pruning others to see which method yields better results.

How to Remove Tomato Suckers

If you decide to remove the suckers, here’s how to do it:

  1. Timing: The best time to remove suckers is when they’re small, ideally less than 2 inches long. They’re easy to pinch off with your fingers at this stage.
  2. Tools: If the suckers are larger, use a clean, sharp pair of pruning shears to avoid damaging the plant.
  3. Technique: Simply grasp the sucker between your thumb and forefinger and gently pinch it off. If using shears, make a clean cut close to the main stem.

When to Prune Your Tomato Plants

Timing is crucial when it comes to pruning your tomato plants. Here’s a quick guide:

  1. Early Season: Start pruning when your plants are young and still manageable. This creates the conditions for robust growth.
  2. Mid-Season: Continue to monitor your plants throughout the growing season. Remove any new suckers that appear.
  3. Late Season: As the season winds down, focus on maintaining good airflow and light penetration to ripen the remaining fruit.

Common Mistakes to Avoid

Even experienced gardeners can make mistakes when it comes to pruning tomato suckers. The following typical traps should be avoided:

  1. Over-Pruning: Removing too many leaves and branches can stress your plant and reduce its overall vigor.
  2. Under-Pruning: Allowing too many suckers to grow can lead to a tangled, unmanageable plant with smaller fruit.
  3. Using Dirty Tools: Always use clean, sharp tools to prevent the spread of diseases.

Pruning Determinate vs. Indeterminate Tomatoes

There are two primary varieties of tomato plants: determinate and indeterminate. Each requires a slightly different pruning approach.

Determinate Tomatoes

Tomatoes that are determined develop to a specific size before stopping. They tend to produce their fruit all at once. For these plants, it’s best to do minimal pruning. Removing too many suckers can reduce your harvest.

Indeterminate Tomatoes

Indeterminate tomatoes bear fruit all season long and continue to grow. These plants benefit the most from regular pruning. Removing suckers helps keep them manageable and productive.

The Role of Mulching

While we’re on the topic of plant care, let’s talk about mulching. Mulch can play a vital role in the health of your tomato plants.

  1. Weed Control: Mulch helps keep weeds at bay, reducing competition for nutrients and water.
  2. Moisture Retention: A layer of mulch helps retain soil moisture, which is crucial for tomato plants.
  3. Temperature Regulation: Mulch can help moderate soil temperature, keeping your plants’ roots cool in the summer.

Companion Planting with Tomatoes

Did you know that some plants make excellent companions for tomatoes? Companion planting can help you get the most out of your garden space and improve your tomato crop.

  1. Basil: This aromatic herb is said to improve the flavor of tomatoes and repel pests.
  2. Marigolds: These bright flowers can help deter nematodes and other harmful insects.
  3. Carrots: Planting carrots near tomatoes can help break up the soil and improve drainage.

Dealing with Common Pests and Diseases

Even with the best care, tomato plants can fall victim to pests and diseases. Here are some common issues and how to address them:

  1. Aphids: These tiny insects can be washed off with a strong spray of water or controlled with insecticidal soap.
  2. Blight: To prevent blight, practice crop rotation and avoid overhead watering. Remove and destroy infected plants.
  3. Tomato Hornworms: These large caterpillars can be hand picked off your plants. Look for their droppings to spot them.

Harvesting and Storing Your Tomatoes

It’s time to savour the results of your labour after all your hard work! Here’s how to harvest and store your tomatoes for maximum flavor and freshness.

  1. Ripeness: Harvest tomatoes when they’re fully colored and slightly soft to the touch. Overripe tomatoes can be used for sauces and soups.
  2. Storing: Store tomatoes at room temperature, out of direct sunlight. For long-term storage, consider canning or freezing.
