Conseils de culture
Harvest stigmas the morning flowers open — use tweezers to pluck the three red stigmas from each flower, then dry at 40-50C within hours.
Saffron is labor-intensive: one hectare requires 300-400 person-hours for the 2-3 week autumn harvest window; plan labor availability accordingly.
