1. Seed harvesting and treatment

This is a very troublesome step and requires special attention. We can harvest seeds from October to November. When the outer skin of the seed is black, it indicates that it can be collected. After the harvest, we should sand them immediately. Before and after the Tomb Sweeping Day in the second year, take them out, remove the peel and seed shell, and soak them in 0.1 acid solution for about a day before sowing. Without special treatment, it is difficult for the sown seeds to germinate. 2. Choice of time

As mentioned above, it is basically the same as the time of seed removal and treatment

3. Matrix selection

In order to improve the survival rate of sowing, of course, we have to choose the substrate carefully. In view of the habit of this plant, the factors we need to consider when selecting the substrate include whether it is fertile, whether the drainage performance is good, etc

4. Specific steps

The seeds that have been specially treated shall be sprinkled on the substrate as much as possible, and then covered with a layer of soil, which shall be slightly thicker. After that, cover it with a layer of grass. Around June, the seeds can germinate and be unearthed. At this time, the covered grass can be removed, but the sun should be properly shaded. About four or five years later, the transplant can be officially carried out

5. Precautions for transplantation

First of all, we should do it in a semi shaded environment and not be exposed to too strong light. In addition, the time should also be paid attention to. It is better to carry out in the early spring. In addition, topdressing and moisture can not be ignored
