Storing Tomatoes Indoors Turning Green Tomatoes Red


Tomatoes are a popular vegetable to grow in gardens and are enjoyed by many people. However, sometimes you may notice that the ends of your tomatoes stay green, even when the rest of the fruit is ripe. This can be frustrating and leave you wondering why this is happening. In this article, we will explore the reasons behind this phenomenon and provide some tips to prevent it from happening.

Reasons for Green Ends

There are several reasons why the ends of your tomatoes may remain green:

Inadequate Calcium

One common cause of green ends in tomatoes is a lack of calcium. Calcium is essential for the proper development and ripening of fruits. When there is not enough calcium available in the soil, the fruit may not be able to fully ripen, resulting in green ends. This condition is known as blossom-end rot.

Inconsistent Watering

Another factor that can contribute to green ends is inconsistent watering. When tomato plants experience fluctuations in moisture levels, it can affect the uptake of nutrients, including calcium. Inadequate watering or overwatering can both lead to green ends in tomatoes.

High Temperatures

High temperatures can also play a role in causing green ends in tomatoes. When the weather is excessively hot, the fruit may not be able to ripen evenly. This can result in green patches at the ends of the tomatoes.

Preventing Green Ends

While green ends in tomatoes can be frustrating, there are steps you can take to prevent this issue:

Ensure Sufficient Calcium

To prevent blossom-end rot, it is important to ensure that your tomato plants have access to sufficient calcium. You can do this by adding calcium-rich amendments, such as crushed eggshells or agricultural lime, to the soil before planting. Additionally, maintaining a consistent soil pH between 6.5 and 7.0 can help improve calcium availability.

Water Consistently

To avoid fluctuations in moisture levels, it is crucial to water your tomato plants consistently. Water deeply and regularly, ensuring that the soil remains evenly moist. Avoid overwatering, as this can lead to other issues such as root rot.

Provide Shade

If you live in an area with high temperatures, providing shade to your tomato plants can help prevent green ends. You can use shade cloth or plant taller crops nearby to provide some relief from the intense sunlight.


While it can be frustrating to see the ends of your tomatoes stay green, understanding the reasons behind this issue can help you prevent it in the future. By ensuring sufficient calcium, watering consistently, and providing shade in high-temperature conditions, you can help your tomatoes ripen evenly and enjoy a bountiful harvest.
