The most favorable period for harvesting lavender for essential oil is during the mass flowering, when 70-80% of the flowers have bloomed. Harvesting is done in quiet, dry and sunny weather from 9 to 16 hours. The inflorescences are harvested together with the flower stalks, not longer than 10-15 cm. The harvesting is done mechanically with lavender harvesters on flat areas or by hand with a sickle on sloping mountain areas. The essential oil is obtained by steam distillation of fresh inflorescences, and the concrete – by their extraction.

If the inflorescences are harvested for dry color, they are left to dry in a dry and ventilated place, after which they rot.

The average yield per decare from the second year of vegetation is 100-150 kg per decare of dry flowers, and from the third to the tenth year the yields are about 300 kg per decare of dry flowers. Distillation yields from 7 to 15 kg per decare of essential oil.
