The essential oil is contained in inflorescences. Clary sage has spring, winter and biennial forms. In industry winter varieties are very popular.
During autumn sowing it is not recommended to process sage seeds, because it may lead to their intensive germination up to the frosts coming.
The first top-dressing need to be done with 2,0?3,0% solution of “Riverm” in the phase of 1-2 leaves. If the top-dressing is done during the closing crops, solution concentration must be 3,0?4,0%. Anyway dressing should be performed not later than 8-10 prior inflorescence formation. Sage of the second year grows faster and therefore they use 4,0?5,0% solution of “Riverm” for dressing.
