1. Ramet propagation

Ramet planting can be carried out after the beginning of spring. First, prepare the stored root tubers, cut the sprouted root tubers, plant them in the soil and cultivate them normally. In this way, it can bloom in autumn. The advantages of split planting are high survival rate, economical, simple and convenient, but the disadvantage is that the reproduction coefficient is not too high

2. Cutting cultivation

To cultivate Dahlia by cutting, first select the plants in good condition, cut the branches with buds as cuttings, and insert them into the soil base with good drainage performance and sufficient nutrients. The disadvantage of this method is that the survival rate is not as high as that of ramet culture. The later management is troublesome. From weeding, topdressing to pest control, we can't make mistakes in order to maintain it

3. Seed planting

Select the seed planting method, first select the culture plate, which is made of soil with uniform soil, good drainage and disinfected soil. Then spread the seeds on the soil foundation and cover it with a layer of fine soil. Finally, cover the whole soil foundation with film to create a cultivation atmosphere of high temperature and humidity, and wait for it to germinate

4. Daily care

When Dahlia grows into a plant, it is necessary to set up a brace for the branches. First, it is to make the flowers look better, and second, it is to prevent the flowers from crushing the branches. It also needs reasonable fertilizer supply. It has a large demand for nutrients before and after flowering. It should be supplemented with nutrients at an appropriate time to avoid insufficient nutrients affecting the flower posture
