Is there anything else to process apple trees in the fall? Yes! This is Bordeaux fluid. And here we will again meet with the already known copper sulfate, which in this case is used together with quicklime.

In another vessel, 50 liters of quicklime are made in exactly the same way.
Important: application rules
Before use, a solution of copper sulfate is poured into a milk of lime in a thin and continuous stream. The mixture is constantly stirred! If this rule is not observed, then a violent chemical reaction can occur, the result of which is often severe chemical burns on the hands and face.
