What Causes My Tomato Plants to Have Blossom Rot

Tomatoes are one of the most popular vegetables grown in home gardens. However, gardeners can be dismayed when their tomato plants experience blossom rot. Blossom end rot is a physiological disorder that can damage your tomato crop, causing it to rot prematurely. The following are the causes of blossom rot in tomato plants.

Lack of Calcium

Calcium deficiency is one of the leading causes of blossom end rot in tomato plants. Calcium is essential for a plant's growth, and a lack of it can lead to blossom rot. When there is not enough calcium in the soil for the plant to absorb, the fruit tends to be more susceptible to rotting. To combat this issue, it is important to provide your tomato plant with adequate calcium. You can add crushed eggshells or calcium-rich fertilizer before planting to supplement the soil with calcium.

Inconsistent Watering

Another cause of blossom end rot is inconsistent watering. Tomatoes need regular watering to thrive, and a lack of water can cause the fruit to develop blossom rot. Inconsistent watering creates an environment where the plant is unable to absorb the calcium needed for healthy fruit. It is important to regulate the water supply to your tomato plants to prevent blossom rot. Water your plants regularly, and ensure that they have ample water at all times to avoid fluctuations in soil moisture levels.

Acidic Soil

Acidic soil can also contribute to the development of blossom end rot in tomato plants. When the soil is too acidic, it can prevent calcium from being absorbed into the plant. As a result, the fruit is more prone to developing blossom rot. A pH level of 6.0 - 6.8 is ideal for tomato plant growth. You can test the pH level of your soil and add lime or wood ash to make the soil less acidic.

Extreme Temperatures

Extreme temperature fluctuations can also cause blossom end rot in tomato plants. High temperatures can cause the soil to dry out rapidly, making it difficult for the plant to absorb calcium. On the other end, low temperatures can inhibit the plant's growth, making it difficult for the plant to absorb nutrients. It is important to regulate your tomato plant's temperature by ensuring that they receive ample sunlight and that you cover them with shade cloth during extreme heat or cold.

Conclusion

Blossom end rot is a common problem among tomato plants, but it can be prevented. Calcium deficiency, inconsistent watering, acidic soil, and extreme temperatures are all factors that can contribute to the development of blossom rot. If you detect the issue early, it can be addressed by supplementing your soil with calcium or lime, watering your plants regularly, and regulating your plant's temperature. With proper care and management, your tomato plants can thrive and produce a large, healthy crop.
