Its seeds have a dormant period. If it is bred directly, it will take more than a year to grow seedlings slowly. Therefore, if it wants to breed seedlings successfully, it must first treat the seeds to break its dormancy period.

First soak its seeds in water for 1 to 2 days, then take them out, add a proper amount of wet sand, and then hold the wet sand into a ball until no water seeps out. Then put it into a container and water it to keep it moist. This treatment method is mostly used in winter, and then in spring, it can be taken out to dry, and the seeds can be planted in the flower soil when they are half cracked.

Second, other planting methods

The most commonly used method in production is to use cuttage of flower branches to raise seedlings, which will make it easier to survive. Cut off its shoots and put them in the soil to take root.

If it is a rare variety, it is difficult to cut. At this time, we can cultivate seedlings for it by layering or grafting, so that it can bloom that year.

If it is used as a potted seedling, it is necessary to choose some old branches with better varieties and then raise them by layering. If you are a small seedling of cut flowers, you should choose a colorful variety that can form flower branches to raise seedlings, so that it looks better.
