Trees need to be processed and prepared for winter. In autumn, you need to have time to carry out the processing, which is considered the most correct. And no systemic insecticides during this period. They are powerless during this period against diseases and pests.

How to treat trees

After the leaves fall, you can make a solution for spraying. It includes the following components:

• urea (urea) – 700 g;
• copper sulfate – 300 d;
• water – 10 l.

Please note that such solutions are made in plastic containers. If suddenly you do not have copper sulfate, then you can use iron sulfate. However, the dose should be increased to 500 g. When processing, not only the branches and the trunk, but also the trunk circle should get under the solution.
