Why do tomatoes crack in the greenhouse and in the open ground?

Every vegetable grower expects a rich and high-quality harvest. And when the fruits have already gained a good mass or even started to keep up, cracks appear. Why do tomatoes crack on the vine? Having understood the reason, it will be possible to stop the appearance of new defects. Do not forget that the cracks not only spoil the appearance of the fruit, but also serve as a hotbed for the penetration and spread of various infections.

So, why do tomatoes crack on the bushes? The first and the main reason is incorrect agricultural technology. Excessive or insufficient watering results in the plant trying to collect 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 - slightly moisten the ground on the first day, and after a day it is good to water the tomatoes. In order to avoid a drastic drying, the soil around the plants must be covered up.

The next reason why tomatoes crack is related to 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 crack is excess fertilizer. Especially in this respect, nitrogen-containing mixtures or natural substances containing nitrogen, for example chicken manure, are dangerous . You do not need to completely abandon fertilizers, but you must clearly adhere to the recommended dosages.

Another reason why tomatoes crack is the sudden change in temperature and humidity. If the plant grows in the open ground and weather forecasters predict a sharp temperature drop, it may be worth collecting tomatoes and letting them ripen in the box. Tomatoes in the greenhouse, a sharp change in weather conditions is not terrible, but here it is best to maintain optimal conditions: humidity 50% and temperature no higher than 25 ° C.

Quite often, truckers have a question: why do tomatoes crack for no apparent reason? It seems that the irrigation regime is optimal, and fertilizers were brought in the right proportions, and the weather is the 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 meant 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.

Here are all the main reasons that can lead to the appearance of cracks in tomatoes. Applying the right agrotechnics and choosing suitable tomato varieties, you can avoid the appearance of such a problem and get a wonderful harvest.
