Preventing Blossom End Rot in Purple Russian Tomatoes

Blossom end rot is a common physiological disorder that affects tomatoes, including the Purple Russian 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 and eventually turning brown or black.

Causes of Blossom End Rot

Blossom end rot is primarily caused by a calcium deficiency in the developing fruit. However, it is not necessarily a result of a lack of calcium in the soil. Instead, it is often due to fluctuations in soil moisture levels, which can disrupt the plant’s ability to absorb and transport calcium to the developing fruit.

Preventive Measures

Here are some preventive measures you can take to minimize the occurrence of blossom end rot in your Purple Russian tomatoes:

Maintain consistent soil moisture: Ensure that the soil remains consistently moist but not waterlogged. Mulching around the plants can help retain moisture and regulate soil temperature.

Avoid over-fertilization: Excessive nitrogen fertilization can contribute to blossom end rot. Use a balanced fertilizer and follow the recommended application rates.

Monitor soil pH: Tomatoes prefer slightly acidic soil with a pH between 6.0 and 6.8. Test your soil regularly and adjust the pH if necessary.

Provide adequate calcium: Although calcium deficiency is not always the cause of blossom end rot, ensuring an adequate supply of calcium can help prevent its occurrence. You can add calcium-rich amendments, such as gypsum or crushed eggshells, to the soil before planting.

Avoid excessive pruning: Pruning tomato plants excessively can lead to increased sun exposure on the fruit, making them more susceptible to blossom end rot. Maintain a balanced canopy by selectively removing only the necessary branches.
