Harvesting tomatoes with blossom end rot may not be ideal, but understanding how to manage this issue can help you salvage your crop. Blossom end rot is a common problem caused by calcium deficiency, which results in dark, sunken spots at the blossom end of the fruit. While affected tomatoes are not suitable for consumption, addressing the underlying causes can improve future harvests.
What Is Blossom End Rot and How Does It Affect Tomatoes?
Blossom end rot is a physiological disorder that primarily affects tomatoes, peppers, and squash. It occurs when the plant is unable to absorb sufficient calcium, leading to the breakdown of cell walls at the blossom end of the fruit. This results in dark, leathery spots that can make the fruit inedible.

Causes of Blossom End Rot:
- Inconsistent watering
- Calcium-deficient soil
- Rapid plant growth
- High nitrogen levels
-
Signs to Look For:
- Dark, sunken spots at the fruit’s blossom end
- Spots may enlarge and turn black
- Affected fruits may become deformed
Can You Eat Tomatoes with Blossom End Rot?
While tomatoes with blossom end rot aren’t suitable for eating fresh, you can cut away the affected area and use the remaining part if the damage is minimal. However, the quality and taste might be compromised, making them less desirable for consumption.
How to Prevent Blossom End Rot in Tomatoes
Preventing blossom end rot is key to maintaining a healthy tomato crop. Here are some effective strategies:
-
Ensure Consistent Watering:
- Water plants deeply and regularly, especially during dry spells.
- Mulch around plants to retain moisture and regulate soil temperature.
-
Test and Amend Soil:
- Conduct a soil test to check calcium levels.
- Add lime or gypsum to increase calcium if needed.
-
Avoid Over-Fertilizing:
- Use balanced fertilizers to prevent excessive nitrogen, which can inhibit calcium uptake.
- Opt for slow-release fertilizers to provide nutrients gradually.
-
Use Calcium Sprays:
- Apply calcium sprays to foliage as a temporary measure.
- This can help address immediate deficiencies but is not a long-term solution.
Practical Example: A Gardener’s Experience
Jane, a home gardener, noticed blossom end rot on her tomatoes last season. By adjusting her watering schedule and adding lime to her soil, she successfully reduced the incidence of the disorder. This season, her tomato plants are thriving, with healthy, rot-free fruits.
Frequently Asked Questions
Can Blossom End Rot Spread to Other Fruits?
No, blossom end rot is not a disease and does not spread from fruit to fruit. Each affected fruit is an isolated incident caused by the plant’s inability to absorb calcium.
How Can I Quickly Add Calcium to My Soil?
For a quick calcium boost, you can use calcium sprays on the plant leaves. However, for long-term soil improvement, consider adding lime or gypsum to your soil based on a soil test.
Are There Tomato Varieties Resistant to Blossom End Rot?
While no tomato variety is completely immune to blossom end rot, some varieties are less susceptible. Consider planting Roma or cherry tomatoes, which tend to be more resistant.
Does Temperature Affect Blossom End Rot?
Yes, extreme temperatures can exacerbate blossom end rot. High temperatures can increase water evaporation, leading to inconsistent moisture levels and reduced calcium uptake.
How Long Does It Take to Correct Blossom End Rot?
Correcting blossom end rot can take a few weeks to a growing season, depending on the severity and the corrective measures implemented. Consistent care and soil management are crucial for improvement.
Conclusion
Addressing blossom end rot in tomatoes involves understanding its causes and implementing preventive measures. Consistent watering, soil testing, and balanced fertilization are essential steps in preventing this common issue. By taking proactive measures, you can enjoy a bountiful and healthy tomato harvest.
