Have Vorox ordered for the second time. Especially for Giersch it is highly recommended. The spraying of this bottle is excellent. One can very specifically and very low deal with it. Especially minimally sprayed between the terrace stones, it has an excellent effect. You just have to show some patience, not immediately wilts Giersch and other weeds, such as grass between stones, slowly at first, and after 14 days it's gone.
