Why Are My Tomatoes Cracking on the Plant?

Tomatoes are one of the most popular and versatile vegetables, used in a variety of dishes all around the world. They are also relatively easy to grow, making them a favorite among home gardeners. However, when tomatoes crack on the plant, it can be frustrating and disappointing. Here are some of the reasons why this might be happening.

Overwatering

One common cause of tomato cracking is overwatering. When plants receive too much water, the fruit may swell quickly, causing the skin to split. To avoid this, make sure to water your tomato plants only when the soil is dry to the touch. You should also try to water them deeply, so the roots have a chance to absorb moisture before it evaporates from the surface.

Underwatering

While overwatering can cause cracking, so can underwatering. If your tomato plants are not getting enough water, the fruit may not be able to grow properly. As a result, it may become too dry, leading to cracks. To prevent this, make sure to water your plants regularly and deeply, especially during hot and dry weather.

Inconsistent Watering

In addition to overwatering and underwatering, inconsistent watering can also cause cracking. This is because the tomato fruit needs consistent moisture to grow properly. If you water your plants irregularly, the fruit may not be able to adapt to the changes, leading to cracks. To avoid this, try to maintain a consistent watering schedule and make sure your plants receive enough water throughout the growing season.

Heavy Rainfall

Another possible cause of tomato cracking is heavy rainfall. When there is too much rain, the fruit may absorb too much water too quickly, causing it to swell and split. To prevent this, you may want to cover your plants with a plastic sheet or some other protective covering when there is heavy rainfall.

Drought Conditions

On the other hand, drought conditions can also contribute to tomato cracking, especially if the plants are already stressed. When there is not enough water, the fruit may become too dry and hard, making it more prone to cracking. To prevent this, make sure to water your plants regularly and deeply, especially during dry spells.

Genetics

Finally, some tomato varieties are more prone to cracking than others, due to their genetics. If you are experiencing frequent cracking, it may be worth trying a different variety next season, to see if that helps. In the meantime, you can also try to prevent cracking by maintaining consistent watering and avoiding extreme weather conditions.

Overall, there are several possible causes of tomato cracking, ranging from overwatering to genetics. By understanding these factors, you can take steps to prevent cracking and enjoy a successful tomato harvest.
