Unfortunately, it often happens that tomato flowers begin to turn yellow, dry out and fall off.
The reason is banal and simple – lack of nutrients.
By the way, this unpleasant phenomenon is observed mainly on tall tomatoes, because they need almost 2 times more nutrition compared to determinate tomatoes.
Every summer resident who encounters such a problem should take immediate action if, of course, he does not want to be left without a harvest.
This means that it is necessary to add such essential plant elements as manganese, boron, phosphorus and potassium.
An excellent source of phosphorus is superphosphate, while tomatoes can obtain potassium from ash.
Manganese and boron can be found in other fertilizers - all you need to do is carefully examine the packaging.
Fertilizing must be done on damp soil - after watering or after the dust on the ground has been washed away by heavy rain.
