There are three kinds of time to plant this kind of flower, depending on the time when you want to bloom. If you want to bloom in spring and may, you have to plant in January. If you want to bloom after overwintering, there are two ways. The first one can be sown directly in the open air, but it must be started in July and August if it is earlier. Another time later, but to be carried out in the greenhouse, August to September sowing can
After sowing, it is necessary to keep a relatively balanced humidity and cover the surface of the seed lightly with vermiculite. If the temperature reaches 20 - 21 ℃, a little more than a week can sprout
After the cotyledons are fully expanded, the environment needs to be adjusted. At this time, the temperature and humidity need to be reduced appropriately. It only needs 17-20 degrees to be suitable for the growth of seedlings. Then, about 6-8 weeks later, the seedlings will grow up. At this time, the space is particularly important. We need to move them to a nest and put them in a flowerpot with a diameter of 8-15 cm. If you want to raise two or three plants together, you can put them in a 10-12 cm flowerpot. There are also requirements for the soil of flowerpot. The upper basin must be loose and coarse-grained herbaceous soil with slightly acid soil. The temperature should be kept at 13 ~ 17 ℃ to make it grow normally.
The temperature is 3-5 ℃, and there is no frost, it can survive the winter normally. If it is cultured outdoors, it can be kept warm by using fabrics, and it can also survive the winter safely. When the temperature rises to 15-18 ℃, it will take 10-11 weeks to bloom. Low temperature of 7 ~ 12 ℃ is not suitable for growth, and will prolong the whole cycle. If the temperature is lower, the growth will stop
This method is more simple and has lower requirements for various conditions. When dividing plants, we must select clustered plants and separate them with knives. Each plant needs to leave 1-2 buds to be cultured in a basin for nutrition. The only thing we need to pay attention to is that we must do a good job of heat preservation in winter, otherwise it is easy to cause seedling death. After rametting, continue to breed according to the normal method, there is no other place to pay attention to, the difficulty of operation skill is low
