The climate, determining element of the lavender harvest
The picking of lavender obeys precise climatic rules. It depends on the hygrometry, that is to say on the humidity of the air. Clearly, a long period without rain can advance the harvest of a few days, while a thunderstorm can delay it by the same amount. Do not hesitate to inquire at the tourist offices of the areas in which you want to go.
The flowering period of lavender extends from mid-June to the end of August.
It varies according to lavender varieties, climate, altitude and latitude. Local weather is also a determining factor for picking.
