This disease is not fungal. It arises from our improper care of culture. It is important to understand why this is happening. As many experts say, this is a problem of lack of calcium in the soil. Although the soil always contains this substance, sometimes tomatoes simply do not absorb it. So what are the true causes of blossom end rot?

1. Irregular or incorrect watering. Tomatoes are under a lot of stress if they are watered occasionally. Many summer residents practice just this option. Arriving at the site, they pour a huge amount of water under the bushes, and then for a week or even more, they do not appear on the site.

2. There is too much water in the soil. Some gardeners thickly mulch tomato beds. Sometimes it makes it difficult to watch how the earth dries up. The overflow factor of plants has a very strong influence on the appearance of blossom end rot.

3. Improper use of potassium and calcium fertilizers can also cause disease. If a large amount of potassium is introduced into the soil, then the tomatoes will absorb calcium much worse. Accordingly, it is calcium that they will lack. In this case, you can water the plant under the root with calcium nitrate. But in such a situation, a lack of potassium may be detected. Therefore, it is very important to observe the correct proportion of these elements.

4. Excess nitrogen fertilizer also adversely affects tomatoes and other crops, which are also susceptible to blossom end rot.
To remedy the situation, you should reduce watering for a while and monitor the surface condition of the soil. It should have time to dry out before the next watering. It is also desirable to reduce top dressing, especially with nitrogen fertilizers. In addition, until the situation is corrected, ash should not be applied to the soil.

It should be borne in mind that different varieties of tomatoes react differently to this disease. Cherry tomatoes are generally not susceptible to this ailment, like the black variety of tomato. Plum varieties and varieties of yellow tomatoes are most often affected.

By following simple rules, gardeners can independently cope with a disease such as top rot of tomatoes. It is enough to correct the rules of watering and maintain a balance in nutrient dressings.
