What Causes Tomatoes to Crack: Understanding the Factors
What Causes Tomatoes to Crack?
Tomatoes crack primarily due to overwatering.
This can lead to radial or concentric cracking, exposing the flesh to diseases and pests.
Quick and extreme changes in temperature can also cause cracking.
Tomatoes can split at any stage of growth, be it green or ripened.
However, tomatoes with cracks can still be eaten as long as they don’t smell sour, ooze, or show signs of pests or diseases.
Harvesting the fruits as soon as cracks appear and allowing them to ripen indoors can salvage them.
Although they may not be as tasty as vine-ripened ones, if the bad parts are cut off and the rest is firm and looks/smells okay, they can still be consumed.
Preventing cracking involves keeping the soil evenly moist, using appropriate irrigation systems, keeping leaves dry, and using organic mulch or compost.
Additionally, picking tomatoes before heavy rain and planting crack-resistant varieties can help prevent cracking.

Did You Know?
1. The main reason tomatoes crack is due to irregular watering. If they receive inconsistent amounts of water, the inside of the fruit will grow faster than its skin can expand, resulting in cracks.
2. A common misconception is that cracking is caused by overwatering. However, it is actually the sudden influx of water after a period of dryness that causes the fruit to crack, rather than excessive watering in general.
3. The cracking of tomatoes can also be attributed to rapid temperature changes. Fluctuations in temperature cause the fruit to expand and contract abruptly, leading to cracks in the skin.
4. The tomato variety known as “heirloom” is particularly susceptible to cracking. These varieties have thinner, more delicate skins compared to hybrid tomatoes, making them more prone to cracking under the same conditions.
5. Interestingly, tomatoes cracked during the ripening process tend to be sweeter than their uncracked counterparts. The cracks allow for increased sugar concentration within the fruit, enhancing its flavor profile.
Overwatering: The Primary Cause Of Tomato Splitting
Tomatoes are a beloved fruit that can bring vibrant color and delicious flavor to any dish. However, they can sometimes develop unsightly cracks that can affect their taste and appearance. Overwatering is the primary cause of tomato splitting, a phenomenon that occurs when the fruit expands rapidly due to excessive water intake. When tomatoes receive too much water, their cells enlarge and become more susceptible to cracking.
To prevent overwatering, it is important to keep the soil moisture level consistent. This can be achieved by using soaker hoses or drip irrigation systems that deliver water directly to the roots, avoiding excessive water contact with the leaves and fruit. Additionally, keeping the leaves dry can prevent disease and promote healthier tomatoes. Using organic mulch or compost can help retain moisture and regulate soil temperature. Planting tomatoes in raised beds or containers with good drainage is also highly recommended.
Another preventive measure is to perform regular soil tests to check for nutrient imbalances. This can help determine if there is a need for fertilizers or amendments to provide the necessary nutrients for healthy tomato growth. Finally, choosing crack-resistant tomato varieties, which are specifically bred to be less prone to splitting, can significantly reduce the risk of tomato cracking.

Different Types Of Cracks: Radial And Concentric Cracking
Tomato cracking can occur in different patterns and severity. The two main types of cracks are radial and concentric. Radial cracking is characterized by fissures that radiate from the stem, exposing more of the tomato flesh to the outside environment. This type of cracking provides an entry point for pests and diseases, which can compromise the quality and edibility of the fruit.
Concentric cracking, on the other hand, forms rings around the stem and is generally less severe. Although it still impacts the appearance of the tomato, concentric cracking does not expose the insides as much as radial cracking does. However, it is important to note that concentric cracks can still provide opportunities for pests and diseases to enter.
Temperature Fluctuations: A Surprising Cause Of Tomato Cracking
While overwatering is the primary cause of tomato cracking, temperature fluctuations can also contribute to this issue. Quick, extreme changes in temperature, such as a sudden heatwave followed by heavy rainfall or cool evenings, can cause the tomatoes to expand and contract rapidly. This fluctuation in size can lead to splitting of the fruit’s skin.
To mitigate the effects of temperature fluctuations, it is crucial to provide consistent growing conditions for tomatoes. This can be achieved by planting them in a location that receives consistent sunlight and is protected from strong winds. Additionally, taking preventive measures such as providing shading during hot periods and covering the plants during colder nights can help reduce stress on the tomatoes and minimize potential cracking.

- Cover plants during colder nights.
Cracking At Any Stage: From Green To Ripe Tomatoes
It is important to note that tomatoes can split at any stage of their growth, whether they are green and unripe or fully ripened. The susceptibility to cracking varies depending on the variety and individual characteristics of each tomato plant. However, certain steps can be taken to reduce the risk of cracking at different stages of growth.
When tomatoes are still green, it is crucial to monitor their growth and adjust watering and environmental conditions accordingly. As they mature and transition to the ripening stage, frequent inspection is necessary to catch any signs of cracking early on. Additionally, picking tomatoes before heavy rain or extreme weather events can help minimize the chances of splitting.
To summarize:
- Tomatoes can split at any stage of growth.
- Monitor growth and adjust watering and environmental conditions for green tomatoes.
- Inspect mature tomatoes frequently to catch signs of cracking.
- Pick tomatoes before heavy rain or extreme weather events to minimize splitting.
Salvaging Cracked Tomatoes: When To Keep Or Discard
Despite their cracks, tomatoes can still be consumed if certain conditions are met. If a tomato doesn’t smell sour, ooze, or show signs of pests or diseases, it can be safely consumed. However, it is important to inspect each cracked tomato individually before making a decision.
If cracking is mild and doesn’t spread extensively, it is possible to salvage the fruits by promptly harvesting them when the cracks appear and allowing them to ripen indoors. Although these tomatoes may not be as tasty as vine-ripened ones, if the bad parts are cut off and the rest is firm and visually and olfactorily acceptable, they can still be enjoyed. It is important to note that when consuming cracked tomatoes, it is crucial to be cautious and use personal judgment to ensure safety.
Understanding the factors that cause tomatoes to crack is essential for growing and harvesting healthy, flawless fruits. Overwatering, temperature fluctuations, and tomato variety susceptibility all play a role in determining the nature and severity of cracking. By following proper watering techniques, providing consistent growing conditions, and implementing preventive measures, gardeners can reduce the risk of tomato cracking and enjoy a bountiful harvest of delicious, crack-free tomatoes.

Frequently Asked Questions
How do you keep tomatoes from cracking?
To prevent tomatoes from cracking, it is important to maintain a consistent watering schedule. Watering tomato plants once a week with 1-2 inches of water helps to prevent fluctuations in moisture levels that can contribute to cracking. Additionally, applying a layer of mulch around the base of the plants can provide insulation and help to regulate soil moisture, reducing the risk of cracks. Finally, regular feeding with organic Tomato-tone fertilizer every other week during the growing season can ensure that the plants receive the necessary nutrients to develop strong and resilient fruit.
What deficiency causes cracking in tomatoes?
Tomato cracking can occur due to a deficiency in boron. Boron is an essential micronutrient for plants and plays a vital role in cell wall formation. When tomatoes lack sufficient boron, the cell walls become weak and unable to withstand the expansion of water within the fruit, leading to cracking. Adequate boron levels in the soil and proper plant nutrition management are crucial to prevent this undesirable phenomenon and ensure healthy, crack-free tomatoes.
Is it safe to eat tomatoes that have split?
Eating tomatoes that have split can pose potential risks as it can attract fruit flies and result in the growth of fungus, mold, and bacteria. When it comes to tomato canning, it is advisable to skip using cracked tomatoes to avoid any adverse consequences. Nevertheless, if you cut around the cracks and utilize the unaffected parts, incorporating them into salads, sandwiches, salsas, and sauces is still safe and acceptable.
Does overwatering make tomatoes split?
Overwatering tomatoes can indeed lead to splitting. When the plants are flooded with excessive amounts of water, the fruit grows rapidly, causing the skin to stretch beyond its capacity. As a result, the tomatoes become more prone to splitting, as the internal pressure exceeds the threshold of the skin’s elasticity. In addition to the physical strain on the fruit, overwatering can create a hospitable environment for rotting and disease, further compromising the quality and health of the tomatoes. It is important to regularly monitor soil moisture levels and provide the appropriate amount of water to avoid this problem.
