Why did the stalks of tomatoes rot in the greenhouse and the flowers fall off? (film greenhouse) Thank you in advance for your reply?
It is likely that the reason for this phenomenon is improper soil. It can be depleted, or vice versa re-fertilized, which causes rotting processes. Perhaps you water too much, moisture does not evaporate and condensation forms. And this is an ideal environment for the propagation of late blight. The soil and the plants themselves should be treated with a solution of copper sulfate. Do not allow humidity in the greenhouse more than 80%
