Saffron plants are usually cultivated in the open in September. The north should be sooner rather than later, as early as the early emergence of seedlings, after the first root germination, plant growth and robust; late cultivation after the first rooting after germination, plant growth is also poor. Indoor flowering bulbs can be transplanted to Daejeon immediately after harvesting 80% of flowers from late October to mid-November. The remaining 20% ​​of the flowers are picked in the field. Before planting, sort and size the bulbs. Large species are rare and small species are dense. The general spacing and row spacing are 20 cm each, and the ditch depth is about 10 cm. The bulb shoots head upwards, and the height of the corms is 2 to 2.5 times (3 to 16 cm). Deep bulbs are also one of the ways to cultivate large bulbs. After planting, the roots were soaked to keep the soil moist and emerged after about one month. China Agricultural Network Editor
