It can choose to plant in autumn, so that it will bloom in spring. Of course, it can also be planted in summer, so that it will bloom at the end of autumn. Usually sowing time is between August and September.
First prepare the seeds, then plant them in the soil, ensure the appropriate germination temperature, 18 to 21 degrees is the best, and prevent strong light, about a week after germination. The temperature can then be adjusted to 10 to 13 degrees, so that it will bloom in 14 to 15 weeks. After that, the temperature can be controlled at 15 ℃ in the daytime and 3 ℃ to 5 ℃ in the evening.
When the seedlings grow 4 small leaves, they can be planted. When planting, the roots should be kept with soil, otherwise it is difficult to survive. In addition, transplant site to choose drainage, ventilation good place, can not make the temperature too high and moisture too much, or it will affect its growth.
After transplanting, the seedlings should first be given sufficient light, and the growth temperature of 7 to 15 degrees is the best. In this way, the stems and leaves will flourish. Then the water should be appropriate, and the soil should not be too wet or too dry, otherwise it will hinder its growth, and then it should be properly fertilized. At the early stage of its growth, nitrogen fertilizer is the main form, while phosphate fertilizer is the main form of flowering. At last, pests and diseases should be prevented, branches should be properly pruned, and residual branches and flowers should be cut off, so that the plant can grow new branches, produce more flowers, and the flowering period can be appropriately prolonged.
