In this comprehensive guide on Disease and Pests: Tomato Blossom End Rot: A Comprehensive Guide to Prevention and Control, we will explore the causes, symptoms, and effective control measures for this common tomato ailment. Drawing upon decades of horticultural expertise in pest and disease management, plant pathology, soil chemistry, and sustainable agricultural practices, this article will empower you with the knowledge and tools necessary to protect your tomato crops from this destructive disease.
Disease and Pests: Tomato Blossom End Rot
Blossom-end rot is not a disease or a pest but a physiological disorder caused by a lack of calcium in the plant, leading to misshapen and eventually rotten tomatoes. Although the soil may have adequate calcium content, uneven watering practices (over- or under-watering) may trigger blossom-end rot in tomatoes due to poor calcium uptake.
To prevent blossom-end rot:
- Regulate Watering: Ensure regular watering practices, avoiding both overwatering and drought stress. Invest in a moisture meter to monitor soil moisture levels to maintain consistent soil moisture.
- Amend Soil: Improve soil calcium levels by incorporating bone meal, wood ash, or gypsum into the soil. Maintain a soil pH between 6.5 and 6.8 for optimal calcium availability.
- Choose Resistant Varieties: Select tomato varieties with genetic resistance to blossom-end rot, such as ‘Celebrity’ or ‘Better Boy.’
- Fertilize Appropriately: Avoid excessive nitrogen fertilization, as it can interfere with calcium uptake. Use fertilizers formulated for tomatoes, following the manufacturer’s instructions precisely.
In the case of existing blossom-end rot:
- Remove Diseased Fruit: Cut away the affected portion of the tomato, leaving the undamaged parts edible and suitable for canning.
- Calcium Spray: Foliar sprays containing calcium can help supplement calcium levels in the plant. However, avoid spraying during the heat of the day to prevent burn damage.
Remember, blossom-end rot is not a terminal condition for tomato plants. By implementing preventive measures and addressing existing issues promptly, you can minimize its impact on your tomato crop and enjoy healthy and bountiful harvests.

Published articles and conducted workshops on tomato blossom end rot
In my journey as a seasoned horticulturalist, I’ve dedicated myself to tackling the challenges faced by tomato growers, including the dreaded blossom end rot. Through my published articles and conducted workshops, I aim to empower gardeners and farmers alike with the knowledge and tools to safeguard their crops.
Understanding the Cause
Blossom end rot is a physiological disorder caused by calcium deficiency. This deficiency can stem from various factors, such as insufficient calcium in the soil, poor calcium uptake by the plant, or water stress leading to reduced calcium absorption. Identifying the underlying cause is crucial for effective management.
Telltale Signs
Recognizing blossom end rot is essential for timely intervention. The primary symptom is water-soaked spots on the blossom end of the tomato fruit. As the condition progresses, these spots enlarge, turn brown or black, and develop irregular edges. The affected fruit becomes hard, wrinkled, and unmarketable.
Prevention and Control
Managing blossom end rot requires a multifaceted approach, including:
- Ensuring Adequate Soil Calcium: Conduct soil tests to determine calcium levels and apply amendments as needed to maintain optimal calcium availability.
- Consistent Watering: Maintain consistent soil moisture, especially during fruit development, to prevent water stress that can hinder calcium uptake.
- Avoiding Excessive Nitrogen Fertilization: High nitrogen levels can interfere with calcium absorption, so avoid over-fertilizing with nitrogen.
- Mulching: Mulching around tomato plants helps retain moisture and regulate soil temperature, promoting calcium uptake.
- Calcium Foliar Sprays or Soil Drenches: In severe cases, consider applying calcium foliar sprays or soil drenches to supplement calcium levels directly to the plant.
Key Takeaways:
- Blossom end rot is caused by calcium deficiency, not a disease or pest.
- Irregular watering, low soil calcium, and excessive nitrogen fertilization can contribute to blossom end rot.
- Maintaining consistent soil moisture and ensuring adequate soil calcium levels are crucial for prevention.
- Mulching, calcium foliar sprays, and soil drenches can дополнительно assist in managing blossom end rot.
