Why a Tomato Cracks and What to Do About It: Easy Solutions

Tomatoes are a staple in many gardens and a favorite among home gardeners. However, there’s nothing more frustrating than picking a beautiful tomato from the vine only to find a crack on its surface. Tomato cracking is a common problem that can be easily prevented with the right techniques.

In this article, we will explore the different causes of tomato cracking, including excessive water uptake, temperature fluctuations, and inadequate calcium supply. We will provide easy solutions to prevent tomato cracking and help you enjoy a bountiful harvest.

Understanding Tomato Cracking

Tomatoes are one of the most beloved ingredients in the kitchen. They are versatile, flavorful, and packed with nutrients. However, tomato cracking is a common problem that can be frustrating for gardeners.

Understanding the causes of tomato cracking is essential in preventing it from happening and ensuring healthy and productive tomato plants.

The Different Types of Tomato Cracks

Tomato cracks can be classified into two types: radial and concentric. Radial cracks start at the stem and extend towards the blossom end. They are usually caused by sudden temperature changes, particularly hot days followed by cool nights.

Concentric cracks, on the other hand, occur in a circular pattern around the stem. They are caused by overwatering or irregular watering, which leads to excessive water uptake and growth pressure on the fruit skin.

The Main Causes of Tomato Cracking

There are several reasons why tomato fruits crack. One of the main causes is excessive water uptake due to irregular watering or overwatering. When tomato plants receive a sudden influx of water, the fruit skin cannot expand quickly enough, and it cracks.

Another factor is temperature fluctuations, particularly when there are extreme temperature changes from hot to cold. The third cause is inadequate calcium supply, which leads to weak cell walls and makes the fruit more prone to cracking.

Causes of Tomato Cracking Description
Irregular Watering or Overwatering Excessive water uptake leads to rapid growth and pressure on the fruit skin, causing it to crack.
Temperature Fluctuations Sudden changes in temperature, particularly from hot to cold, cause the fruit to expand and contract rapidly, leading to cracks.
Inadequate Calcium Supply Insufficient calcium supply leads to weak cell walls, making the fruit more prone to cracking.

Now that we understand the causes of tomato cracking let’s move on to the solutions that can help prevent it from happening.

Preventing Tomato Cracking: Watering Techniques

Effective watering techniques play a crucial role in preventing tomato cracking. Inconsistent watering and overwatering are common culprits of this problem. Here are some tips to help you water your tomato plants properly:

  1. Water consistently: Tomato plants need a consistent supply of water to grow healthy and strong. Water them deeply once every 3-5 days, depending on the weather conditions and soil moisture.
  2. Avoid overwatering: While it’s important to keep your tomato plants hydrated, overwatering can lead to fruit cracking. Make sure only to water the soil around the plants and not the leaves or stems.
  3. Use mulch: Applying a layer of mulch around your tomato plants can help retain moisture and reduce water stress. Choose organic materials, such as straw, grass clippings, or shredded leaves.
  4. Consider drip irrigation: Drip irrigation systems are a great option for watering tomato plants. They deliver water directly to the root zone, minimizing water waste and reducing the risk of fungal diseases.
  5. Water in the mornings: Water your tomato plants in the mornings when the soil is cool, and the sun is not too strong. This will help ensure that the plants have enough moisture to make it through the day.

By following these watering techniques, you can reduce the risk of tomato cracking and enjoy healthy, flavorful fruits.

Preventing Tomato Cracking: Temperature and Tomato Care

Temperature fluctuations can be a leading cause of tomato cracking. Tomatoes thrive in warm temperatures, but sudden drops in temperature, especially at night, can cause the fruit to expand and contract rapidly, resulting in splits on the skin.

To avoid this, it is essential to maintain a stable temperature around your tomato plants. Covering them with blankets or tarps when the temperature drops can help preserve warmth. Additionally, planting your tomato plants in full sun and ensuring adequate air circulation can help regulate temperature.

Another way to prevent cracking is to avoid over-fertilizing your tomato plants. Excess nitrogen and potassium can encourage rapid growth, leading to more extensive fruit that is more susceptible to cracking.

Proper watering is also essential in preventing tomato cracking due to temperature fluctuations. It is crucial to ensure consistent watering to keep the soil around your tomato plants at a stable temperature. Overwatering your plants can result in increased water uptake that can cause the fruit to expand and split open.

By paying attention to temperature and tomato care, you can reduce the risk of tomato cracking and enjoy a bountiful harvest of healthy, delicious tomatoes.

Providing Calcium for Healthy Tomatoes

Calcium plays a crucial role in keeping tomato fruits healthy and preventing cracking. A calcium-deficient plant is more prone to cracking or developing blossom end rot, a fungal disease that affects the bottom of the fruit.

There are several easy ways to add calcium to your tomato plants:

Method Description
Add eggshells Crush up eggshells and mix them into the soil around your tomato plants. The eggshells will decompose over time, releasing calcium into the soil.
Use calcium-rich fertilizers Choose fertilizers with a higher calcium content, such as those made from bone meal or crab meal.

Remember that too much calcium can also be harmful to your plants. Be sure to follow the recommended amounts and application methods for any calcium supplement you use.

By providing your tomato plants with adequate calcium, you can help prevent cracking and ensure healthy, robust tomato fruits.

Tomato Variety Selection

When it comes to preventing tomato cracking, selecting the right tomato variety can make a huge difference. Some varieties are more prone to cracking than others, so it’s important to choose crack-resistant ones to minimize the risk of cracking.

One common characteristic of crack-resistant tomatoes is a thicker skin that is more resistant to splitting. Some popular varieties to consider include ‘Celebrity,’ ‘Big Beef,’ and ‘SuperSauce.’

It’s also important to keep in mind that some heirloom varieties are more susceptible to cracking due to their thinner skin and delicate structures.

If you’re set on growing heirlooms, consider choosing varieties that have been bred for resistance to cracking, such as ‘Cherokee Purple’ or ‘Black Krim.’

Harvesting and Handling Tips

Proper harvesting and handling techniques can help prevent tomato cracking. When picking tomatoes, it’s important to handle them gently to avoid any pressure that can lead to cracking. Choose tomatoes that are firm and fully mature but not overripe.

If you’re picking tomatoes from the vine, use a clean and sharp pair of scissors or pruning shears to avoid tearing or damaging the stem. Hold the tomato gently by the fruit, not the stem.

Another tip is to harvest tomatoes in the early morning when they are cooler and less susceptible to damage. Avoid harvesting in the heat of the day, as the high temperatures can cause the tomatoes to soften and become more prone to cracking.

After harvesting, store tomatoes carefully to avoid damage. Do not stack them on top of each other, and avoid overcrowding in containers. Also, avoid storing tomatoes in direct sunlight, as it can cause them to overheat and spoil quickly.

Natural Remedies for Tomato Cracking

While preventing tomato cracking through proper care and maintenance is the best approach, some natural remedies can help strengthen the skin of your tomato fruits and reduce the risk of cracking.

Foliar sprays: Spraying your tomato plants with a solution of seaweed extract or fish emulsion can help improve the overall health of your plants and increase their resistance to cracking.

Homemade remedies: Some gardeners swear by homemade remedies, such as a mixture of water and aspirin or a spray made from crushed garlic and water. These remedies are thought to boost plant immunity and help prevent cracking.

Remedy Instructions
Aspirin solution Dissolve two aspirin tablets in 1 quart of water and spray on tomato plants every two weeks.
Garlic spray Crush five garlic cloves and let steep in 1 quart of water for 24 hours. Strain and add one tablespoon of dish soap. Spray on tomato plants every two weeks.

Organic approaches: Some organic approaches to tomato cracking prevention can be effective. For example, adding compost to your soil can help improve its structure and increase its moisture retention, reducing the likelihood of water stress that can cause cracking.

“Remember to always test any natural remedy on a small area of your tomato plants before applying it to the entire plant. While these remedies are generally safe, every garden is different, and some plants may be more sensitive than others.”

Common Mistakes to Avoid

While there are several ways to prevent tomato cracking, it’s essential to avoid common mistakes that can contribute to the problem. Here are the most common mistakes to avoid:

  • Over-fertilizing: Too much fertilizer can cause excessive growth, which can lead to larger, more fragile fruits that are prone to cracking. Use fertilizers sparingly and follow the recommended dosage.
  • Improper pruning: Overpruning can expose fruits to direct sunlight, which can cause excessive heat and evaporation, leading to cracking. Avoid over-pruning and ensure that each fruit has enough leaf cover for protection.
  • Inconsistent watering practices: Inconsistent watering can cause fluctuations in soil moisture, leading to uneven fruit growth and cracking. Water your plants regularly and evenly, avoiding overwatering and underwatering.

Avoiding these common mistakes can make a significant difference in the health of your tomato plants and the prevention of cracking. With the right knowledge and techniques, you can enjoy a bountiful harvest of healthy and beautiful tomatoes.
