Copper sulfate is bred in a plastic, enameled or glass container. They work with a chemical like this:

For treatment against lichen and rot, use a 3% agent (30 grams of crystals per 10 liters of water), for insect control - 5% (50 grams per 10 liters of water), for whitewashing, as well as spraying wood wounds - 10% (100 grams of crystals per 10 liters water).

After that, the plant is not touched or watered during the day. In the fight against fungal diseases, the agent is sprayed or applied with a brush to the affected areas. Processing is carried out 2-3 times.
When is it better to spray the area
The summer resident chooses the time of processing plants with copper sulfate himself, taking into account the climatic conditions of the region. So, in the middle lane, this procedure is carried out two weeks before the onset of cold weather. In this case, you must wait until all the leaves fall. In the southern regions, work is carried out at the end of November, as well as in mid or late March, as soon as the weather is warm.
