What Causes Tomatoes to Split on the Plant

Tomatoes are a popular fruit for gardeners and farmers. However, as the fruit ripens, it can often split on the plant. Splitting can not only make the tomato unappealing but can also lead to the tomato being more susceptible to diseases. Here we will discuss what causes tomatoes to split on the plant and how to prevent it from happening.

Tomatoes are a Fleshy Fruit

The primary reason tomatoes split on the plant is that they are a fleshy fruit. When the tomato begins to ripen, a lot of pressure builds up on the fruit. The pressure builds up because the fruit grows faster than the skin on the tomato can expand. Therefore, any forceful impact with a branch or the wind can cause the skin to crack, causing the tomato to split.

Inconsistent Watering

Inconsistent watering is another reason why tomatoes split on the plant. When the tomato plant receives little water and then receives a lot of water, the pressure on the fruit can become too much, and it will split. Additionally, tomatoes that are left dry for too long can split more easily.

Hot Temperatures

Hot temperatures can also cause tomatoes to split on the plant. When temperatures rise, the fruit will ripen faster, putting more pressure on the skin. Higher temperatures result in an increased rate of transpiration, causing the fruit to lose water. The faster water is lost, the more quickly the tomato will ripen, and the more susceptible it will become to cracking and splitting.

Tomato Cultivar and Genetics

The cultivar and genetics of the tomato plant can also play a role in the fruit splitting. Some breeds are more likely to develop splitting or cracking than others. For instance, heirloom tomatoes are more susceptible because they have a thinner skin. A thicker skin will also help protect the fruit from splitting.

Preventing Tomatoes from Splitting

To prevent tomatoes from splitting on the plant, there are several things you can do. Consistent watering is crucial to preventing tomatoes from cracking. Tomatoes need plenty of water to grow, so it is essential to make sure they get enough. Additionally, it is important to make sure the soil is well-drained. Waterlogged soil can cause root rot and can lead to the splitting of the fruit.

Another way to prevent splitting is to provide support for the plant. This can be done by staking or caging the plants, which will help reduce the amount of stress put on the fruit. You should also harvest the fruit as soon as it is ripe since leaving it on the plant for too long can make it more susceptible to splitting.

In conclusion, many factors can cause tomatoes to split on the plant. Avoid inconsistent watering, extreme temperatures, and make sure the soil is well-drained. Additionally, choose tomatoes from sturdier cultivars and provide support for the fruit. By following these steps, you can grow healthy, beautiful tomatoes that are less likely to split on the plant.
