Should You Prune Tomato Suckers?

Understanding Tomato Suckers

Tomato suckers are side shoots that grow at the junction of the stem and a branch. If left unchecked, these suckers will develop into полноценно stems with their own branches, flowers, fruit, and more suckers.

Benefits of Pruning Tomato Suckers

Pruning tomato suckers offers several benefits for plant health and fruit production:

  • Improved plant health: Removing suckers redirects nutrients to the main stem, promoting healthier overall growth and larger, more robust plants.

  • Increased fruit size: By eliminating competition for nutrients, pruning suckers allows the plant to focus its energy on producing larger, higher-quality fruit.

  • Enhanced airflow: Pruning improves airflow through the plant, reducing the risk of disease by allowing leaves to dry faster after rain.

  • Pest control: Removing suckers makes it easier to spot pests that may be camouflaged within dense foliage.

  • Faster fruit ripening: Pruning stimulates the plant to divert energy into fruit development, speeding up the ripening process.

How to Prune Tomato Suckers

The earlier you prune tomato suckers, the easier it will be. Follow these steps:

  1. Snap off small suckers: Use your bare hands to snap off any suckers that are about 1/2 inch in size.
  2. Cut thicker stems: For stems thicker than a pencil, use pruning shears to avoid damaging the plant.
  3. Remove lower leaves: Prune leaves near the base of the plant to prevent soil-borne diseases.
  4. Regular maintenance: Trim suckers and unnecessary flowers on a weekly basis during the peak growing season.
  5. Clean your shears: Disinfect your pruning shears with an alcohol wipe before moving between plants to prevent the spread of disease.

Pruning Considerations

Not all tomato suckers need to be removed. Mature plants may benefit from retaining some suckers to support additional fruit production. However, avoid over-pruning, as some leaves are necessary to protect the fruit from sunscald.

Types of Tomatoes and Pruning

The need for pruning varies depending on the type of tomato:

  • Indeterminate tomatoes: These vine-like varieties, such as cherry tomatoes and Beefsteak, benefit from pruning to control their size and encourage fruit production.

  • Determinate tomatoes: These more compact varieties, such as Roma and Celebrity, do not require pruning as they naturally stop growing after setting fruit.

Timing of Pruning

Pruning can be performed throughout the growing season:

  • At planting: Remove the lower leaves and bury the stem deeply to promote root growth and stability.
  • During the growing season: Remove suckers beneath the first fruit cluster to enhance fruit development.
  • Late-season pruning (topping): About four weeks before the expected first frost, remove the growing tip of each main stem to direct energy into fruit ripening.

Trial and Error in Pruning

Tomato pruning is more an art than an exact science. Start by pruning less rather than more. Over time, you will develop a better understanding of how different varieties respond to pruning.
