The key to saffron cultivation lies in site selection, planting, and field management
Saffron (Crocus sativus) is a perennial herbaceous plant of the genus Crocus in the iris family. Its stigmas can be used as medicine, and also as a spice and dye, giving it relatively high economic value; on the market it is often called Tibetan crocus. It should be noted that saffron is not the same as safflower (Carthamus tinctorius); the two differ clearly in both source and use, so before planting one should first understand its growth habits clearly.
Saffron reproduces mainly by corms, and in production it is generally not sown from seed. It prefers a cool and humid climate, and fears both high temperatures and waterlogging, so it is best to choose a plot with relatively high terrain, good drainage, and loose, fertile sandy loam soil for planting; before planting, the soil should be deeply plowed and sufficient base fertilizer applied.
Planting is mostly carried out in autumn, with corms graded by size planted into the soil, and the soil kept moist after covering. In some areas, the method of flowering indoors and cultivating corms in the field is used, that is, the corms are first placed indoors to flower and have their flowers harvested, and then the corms are moved into the field to continue cultivation. The flowers are mostly picked in the early morning, and the stigmas need to be removed promptly and dried.
Field management focuses mainly on drainage, weeding, and topdressing. During the rainy season, water should be drained promptly to prevent waterlogging and avoid corm rot; during the growing period, attention should also be paid to the prevention and control of pests and diseases. After the aboveground parts wither in summer, the plants enter dormancy; at this time the corms can be lifted, and after removing diseased and damaged corms, they are graded and stored for use in the next season's planting.
Overall, saffron cultivation involves many steps and requires meticulous management. Beginners should first trial-plant on a small area, and only after becoming familiar with the whole process of corm cultivation, flower harvesting, and drying and processing should they gradually expand the scale, so as to obtain relatively stable returns.
