First step to cultivate saffron is seeding of Crocus sativus Corm. For this best time is end of July up to end of August. Pick up of grown flowers begin in start of November and takes about one month. Please note that definition of these times completely depends on the weather specification of the region. After collecting flowers farmers separate Stigma part from the plant.
The top part of Stigma known as “Sargol” and from top part to the margin of red and white part is “Pooshal”. Also, red and white parts together known as “Dasteh” and white part named “Konj”.
