Seasonal plant treatments with copper sulfate
Copper sulfate is used by gardeners to treat plants against fungal and viral diseases. Cultivated plants with external signs of copper starvation are also sprayed with a solution of copper sulfate..
For dressing use solutions of low concentration of the active substance (2-3 g per 10 l of water). Top dressing is carried out during the formation of the ovary and in the summer. Plants with yellow curled leaves are sprayed with this solution every 10 days for a month. After treatments with copper sulfate, the color of the leaves will turn green.
