Tomatoes are a beloved fruit in the world of gardening and cooking, but sometimes they can be a bit elusive. One frustrating phenomenon that tomato growers often encounter is the splitting of tomatoes on the vine. But why do tomatoes split?
Well, the answer lies in the delicate balance of moisture levels. When tomatoes experience dry conditions and then receive heavy rain, the inside of the fruit grows faster than the outer skin, leading to cracks and splits. This can happen in two ways: vertical splits that extend from the top to the bottom of the tomato, or concentric cracks that form around the stem. Green tomatoes are particularly vulnerable to splitting, and if left unattended, they may rot before reaching maturity.
Key Takeaways:
- Tomatoes can split on the vine due to fluctuations in water levels.
- Dry conditions followed by heavy rain can cause the insides of tomatoes to grow faster than the outer skin, resulting in cracks and splits.
- There are two types of splitting: vertical splits and concentric cracks.
- Green tomatoes are more prone to splitting and rotting.
- Harvesting split tomatoes promptly can prevent further damage.

The Causes of Tomato Rot on the Bottom
Tomato rot on the bottom, also known as blossom-end rot, is a common issue that tomato growers encounter. It manifests as brown, black, or leathery patches on the underside of the fruit, starting from the blossom end. The main cause of this condition is a calcium deficiency in the plant. When there is a lack of calcium, the cells in the tomato fruit cannot form properly, resulting in the rotting and discoloration of the affected area.
Blossom-end rot is often attributed to inconsistent soil moisture levels. When the soil is too dry or experiences fluctuations in moisture, the plant’s ability to absorb calcium becomes compromised. Other factors such as over-ripening, soggy soil, and excessive sun exposure can also contribute to the development of blossom-end rot.
“Blossom-end rot is caused by a calcium deficiency in the tomato and is often the result of inconsistent soil moisture.”
To prevent blossom-end rot, it is essential to maintain consistent soil moisture levels. Regular watering, especially during dry periods, helps ensure that the plants receive an adequate supply of calcium. However, it is important to avoid overwatering, as this can lead to other issues such as root rot or fungal diseases. Adding organic matter to the soil, such as compost or well-rotted manure, can also help improve calcium availability for the plants.
In addition to proper watering, it is beneficial to provide some shade to the tomato plants to reduce sun exposure. This can be done by using shade cloth or by planting taller crops nearby to create natural shade. Applying a layer of mulch around the base of the plants helps regulate soil temperature and moisture, preventing dramatic fluctuations that can contribute to blossom-end rot.
Common Causes of Tomato Rot on the Bottom:
- Calcium deficiency in the soil
- Inconsistent soil moisture levels
- Over-ripening of the tomatoes
- Soggy soil conditions
- Excessive sun exposure
By addressing these causes and implementing proper care practices, such as maintaining consistent moisture levels and providing shade, tomato growers can significantly reduce the occurrence of blossom-end rot and enjoy healthier, blemish-free tomatoes.
Tomato Cracking and Inconsistent Watering
Inconsistent watering is one of the major causes of tomato cracking. When tomato plants experience a period of dryness followed by heavy rainfall, the sudden change in moisture levels can lead to the fruit expanding faster than the skin can grow. This ultimately results in the tomatoes splitting open. However, other factors such as calcium deficiency, over-ripening, and excessive sun exposure can also contribute to tomato cracking.
It’s important to note that different types of cracking can occur, including vertical splits that extend from the top to the bottom of the fruit, as well as concentric cracks that form around the stem. These cracks can vary in severity, with concentric cracking being less problematic if it doesn’t expose the interior of the fruit. Green tomatoes are particularly vulnerable to splitting and are more likely to rot before reaching maturity compared to older tomatoes.
To mitigate tomato cracking caused by inconsistent watering, it is crucial to ensure consistent moisture for your tomato plants. Regular and deep watering, providing approximately an inch of water per week, is essential. Additionally, avoiding water splashing on the leaves can help prevent the spread of diseases.
