Sodium bicarbonate solution

A clear, colorless solution with no residue when the baking soda is fully dissolved. A slight white residue may remain visible on the leaves after drying. Observe the test plants: spots or leaf burn indicate that the dose is too high. No results are guaranteed: they depend on the preparation, the time of application, and local conditions.
