Preventing Blossom End Rot in Velvet Red Tomatoes

Blossom end rot is a common physiological disorder that affects tomatoes, including the Velvet Red variety. It is characterized by dark, sunken lesions that appear on the blossom end of the fruit, usually starting as a small water-soaked spot.

Causes of Blossom End Rot

Blossom end rot is primarily caused by a calcium deficiency in the developing fruit. However, it is important to note that the actual problem lies not in the lack of calcium in the soil, but rather in the plant’s inability to take up and transport calcium to the fruit.

Several factors can contribute to the development of blossom end rot:

• Inconsistent watering: Fluctuations in soil moisture levels can disrupt calcium uptake by the plant. It is crucial to maintain consistent soil moisture throughout the growing season.
• Imbalanced nutrient levels: Excessive levels of certain nutrients, such as nitrogen or potassium, can interfere with calcium absorption. Ensuring a balanced nutrient profile is essential.
• Extreme temperatures: High temperatures can increase water loss through transpiration, leading to calcium deficiency in the fruit. Similarly, rapid temperature fluctuations can also contribute to the problem.

Preventive Measures

To prevent blossom end rot in Velvet Red tomatoes, follow these guidelines:

Maintain consistent soil moisture: Water the plants regularly, aiming for a consistent level of moisture in the root zone. Avoid both overwatering and underwatering, as both can contribute to the development of blossom end rot.

Monitor nutrient levels: Conduct regular soil tests to ensure that the nutrient levels are balanced. Adjust fertilizer applications accordingly to avoid excessive levels of certain nutrients that can hinder calcium uptake.

Provide adequate calcium: Incorporate calcium-rich amendments, such as gypsum or crushed eggshells, into the soil before planting. Additionally, foliar sprays containing calcium can be applied during the growing season to supplement the plant’s calcium uptake.

Protect from extreme temperatures: Use mulch around the base of the plants to regulate soil temperature and moisture levels. Consider providing shade during periods of intense heat to reduce water loss through transpiration.
