Tomato Cracking: Causes, Prevention, and Treatment

Table of Contents

As gardeners, we put in a lot of effort to ensure that our plants grow healthy and strong. There is nothing more disheartening than seeing our hard work go to waste due to tomato cracking. In this post, we will explore the causes of tomato cracking and splitting along with prevention and treatment methods.

Overview of Tomato Cracking

Tomato cracking occurs when the skin of the fruit bursts open. This can happen while the tomato is still on the vine or after it has been harvested. There are two main types of tomato cracking - radial and concentric. Radial cracking happens around the stem of the tomato, while concentric cracking forms rings around the tomato.

Causes of Tomato Cracking and Splitting

Rapid Growth and Water Stress

One of the most common causes of tomato cracking is rapid growth followed by water stress. This can happen when there is a sudden influx of water after a dry spell. This causes the inside of the tomato to expand at a faster rate than the skin, leading to cracking.

Temperature Fluctuations

Another common cause of tomato cracking is fluctuations in temperature. When exposed to extreme temperatures, tomatoes may develop unevenly causing the skin to crack.

Dry Conditions Followed by Heavy Rain

Tomatoes that experience prolonged periods of drought followed by heavy rain may also be at risk of cracking. This is because the sudden influx of water can cause the tomato to expand too quickly.

Nutritional Imbalances

Tomatoes require a balanced supply of nutrients to grow healthy and strong. A lack of certain nutrients, such as calcium or boron, can result in weak cell walls and increase the likelihood of cracking.

Prevention and Treatment

Water the Plants Consistently

Consistent watering is essential for preventing tomato cracking. Avoid letting the soil dry out completely and ensure that the plants receive an even supply of water throughout their growth cycle.

Provide Optimal Nutrients

Providing your plants with optimal nutrients is vital to their overall health and can help reduce the risk of tomato cracking. A balanced fertilizer containing calcium and other micronutrients can help strengthen the structure of the tomato's cell walls.

Harvest Tomatoes Before Fully Ripe

Harvesting tomatoes before they are fully ripe may prevent cracking from occurring. Fully ripened tomatoes have a weaker skin and are more susceptible to cracking.

Select Crack-Resistant Varieties

Selecting crack-resistant varieties of tomatoes can significantly reduce the risk of cracking. Some examples of crack-resistant varieties include 'Mountain Fresh Plus,' 'Celebrity,' and 'Better Boy.'

Tomato cracking is a common problem faced by many gardeners. However, with proper care and attention, this issue can be minimized or eliminated altogether. Consistent watering, optimal nutrients, early harvesting, and selecting crack-resistant varieties are all methods that can help prevent tomato cracking.

FAQ

What causes tomato cracking?

Tomato cracking can occur due to several reasons such as rapid growth and water stress, temperature fluctuations, dry conditions followed by heavy rain, and nutritional imbalances.

How can I prevent tomato cracking?

Consistent watering, providing optimal nutrients, harvesting tomatoes before fully ripe, and selecting crack-resistant varieties are all effective methods for preventing tomato cracking.

Does picking tomatoes early help prevent cracking?

Harvesting tomatoes before they are fully ripe may help prevent cracking as fully ripened tomatoes have a weaker skin.

Can I still eat tomatoes that are cracked?

Yes, you can still eat tomatoes that are cracked. However, be sure to cut away the affected area before consuming.

How do I choose crack-resistant tomato varieties?

Some examples of crack-resistant tomato varieties include 'Mountain Fresh Plus,' 'Celebrity,' and 'Better Boy.'

Is it better to water tomatoes in the morning or evening?

It is best to water tomatoes in the morning as this allows enough time for the leaves to dry before nighttime.

How often should I fertilize my tomato plants?

Tomato plants should be fertilized once every two weeks during the growing season.

Are there any home remedies for treating tomato cracking?

Applying a calcium-rich foliar spray or Epsom salt solution may help reduce the risk of tomato cracking.

Can too much sun cause tomato cracking?

Yes, excessive sun exposure may cause uneven ripening, resulting in tomato cracking.

Do all tomato varieties crack or split?

No, not all tomato varieties crack or split. Selecting crack-resistant varieties can significantly reduce the risk of cracking.
