So, why do tomatoes crack on the bushes? The first and the main reason is incorrect agricultural technology. Excessive or insufficient watering leads to the fact that the plant is trying to gain as much moisture as possible. Water enters the fetus, begins its active growth, the thin skin of tomato does not withstand the increased load and crack. Therefore, tomatoes should be watered a little and often. If there was a forced break in watering, do not immediately give the plants water in excess. It is best to break the procedure into two stages: on the first day, slightly moisten the soil, and after a day it is good to water the tomatoes. In order to avoid drastic drying, the soil around the plants must be covered.
The next reason why tomatoes crack,is associated with the intensity of sunlight. Tomatoes, which are long exposed to sunlight, can crack. Therefore, plants planted in the open ground need a little shade on hot days, and the walls of the greenhouse can be covered with lime milk or white material.
Another reason why tomatoes are cracked isthis is an excess of fertilizers. Especially in this respect, nitrogen-containing mixtures or natural substances containing nitrogen, for example chicken manure, are dangerous.

It seems that the irrigation regime is optimal, and fertilizers were brought in the right proportions, and the weather is most favorable, but on the fruits of varying degrees of ripeness, cracks still appear. In this case, most likely, the problem lies in the wrongly selected grade. Some varieties of tomatoes are intended for a particular climatic region, and when growing such a variety under other, even externally favorable conditions, problems may arise. And certain types of tomato are genetically predisposed to cracking, because they have a very thin and delicate skin. As a rule, such kinds include salad and early, early-ripening tomatoes.
