Saffron bulbs are placed indoors from June to October, crocuses can be planted in a room of 10 square meters, flowers are harvested from late October to early November, the growing period of indoor flowers is about 60 days, and the corms are transplanted to the field before the middle of November. Corms can be harvested in the first ten days of May the following year.

Saffron likes a warm and humid environment, the suitable temperature for growth is about 15 ℃, and 16 ℃ to 20 ℃ is suitable for flowering. Generally, the time for planting saffron is autumn, so when is the best month to grow saffron?

Cultivation and management of saffron requires loose, fertile and well-drained sandy loam with a ph of 5.5 to 6.5. Avoid sticky soil and wet water for a long time. The growth is characterized by dormancy in summer, rooting in autumn, long leaves, florescence from October to November, and flowers blooming day and night. It does not bear fruit under general cultivation conditions, and the whole growth period is about 210 days. Both spring flowers and autumn flowers are bulbous flowers planted in autumn. That is, it begins to sprout in autumn, blossoms in winter and spring, the fruiting species bear fruit, and the summer enters the dormant period. The life span of the bulb is one year, which is similar to the tulip, and the new and old bulbs are renewed alternately every year.

Planting from September to October in autumn, the soil should be sowed and ploughed fine, with sufficient rotten organic fertilizer and a small amount of superphosphate as base fertilizer. Row spacing 1Ocm × 20cm, deep 8~1Ocm, covering soil 5-8 cm, weeding in time during growing period, paying attention to drainage after rain, loosening soil and watering in autumn drought to keep soil moist for rooting. If the flower blossoms in October and the quick-acting phosphate fertilizer is applied once in the bud stage, the flower will be big and colorful. After flowering, it is necessary to apply 1 Mel twice cooked cake fertilizer and water in time to promote the growth of corms. In the northern region, it is necessary to cover grass curtains and other things to protect against cold in winter. The following spring, pay attention to watering, to promote the expansion of the new bulb. The following summer entered the dormant period, the aboveground parts of the plant dried up, the whole growth period was about 7 months, and the optimum growth temperature was 10-15 ℃. It can also promote cultivation. After one planting, the bulbs can be dug out and planted after several years of crowding. The corms were stored in a dry chamber of 17-23 ℃.

It is appropriate to choose spring flowering varieties for family potted crocuses. Generally speaking, 5-7 bulbs can be planted in tile pots with a caliber of 15 cm and 18 cm, which can be planted from September to October. After planting, pour water and first put outdoor culture, and then move to the cold room after rooting, the room temperature is slightly higher than the outdoor temperature, give sufficient light to blossom at that time. Hydroponic cultivation can also be used to cultivate crocuses.
