Autumn sowing is early flowering, overwintering in a cold bed, and flowering at the end of spring. Cornflower is not tolerant to transplant, so it must bring soil mass when transplanting, otherwise it is not easy to slow down the seedlings. After the planting survived, the feces and urine of mature people with 5 times water were applied every 10 days or every month, and the fertilization was stopped in March of the following year to wait for flowering.

2. Strong cold tolerance, can be planted in open field in East China, overwintering in North China; like fertile and loose soil; like sufficient sunshine; self-sowing; strong adaptability, easy to cultivate. When cultivating cut flowers, the greenhouse is usually used to promote flowers: sowing in August, planting in September, and producing flowers in February of the following year. The warm land in the customs is generally sown from August to September, the open field is covered with overwintering, it is planted in early spring of the following year, and blossoms in early summer. The northeast is sown in spring in the greenhouse. Because the root of cornflower is taproot and the lateral root is very few, so transplanting should bring soil into the seedling, and if the seedling is large, it is not easy to survive, so it is often direct seeded in spring.

After the seedlings survive after planting, pick the heart once, promote more branches, can blossom more, on the contrary, if there are too many branches, part of the lateral buds should be removed if necessary, larger flowers can be obtained. Because of taproot, it is appropriate to direct broadcast autumn sowing open field cover overwintering, early summer flowering, such as cold bed overwintering can blossom at the end of spring, spring sowing should be sown as soon as possible.

4. Watering: watering once a day is enough in principle, but when it is drier in summer, it can be watered once in the morning and evening to keep the potted soil moist and reduce the temperature of potted plants, but avoid stagnant water.

5. Fertilization: the cornflower likes more fertilizer, and the three-element diluent should be applied once a month during the growth period. If the leaves are too luxuriant, the proportion of nitrogen fertilizer should be reduced, and more phosphorus and potassium fertilizer should be applied before flowering in order to get larger and beautiful flowers.

6. flowering management: cornflower can naturally send out lateral branches, and if there are more lateral branches, the flowers are smaller. If necessary, part of the lateral buds can be removed, and only smaller branches can be left, larger flowers can be obtained. Cornflower is a long-day plant, which has a short sunshine time in winter. if plant lamps are used to supplement lighting at night, it can blossom earlier.
