1、 Split root

It can reproduce by dividing roots. It is generally selected from March to April in spring. At this time, it grows very vigorously, which is conducive to improving the survival rate. Cut the root with a knife. Note that the knife should be sterilized so that there will be no infection. The incision is coated with plant ash to reduce inflammation. After that, it can be planted into the substrate, and the temperature is maintained at 15-22 ℃, which is helpful for later growth

2、 Cutting

If the cutting method is selected, it can be selected from June to August. This is the main breeding method, but the operation is more complex. Cuttings are root tubers that have been sprouted. When the leaves at the base of new buds stretch, they can be stripped from the base and then inserted into sandy loam. A small amount of rotten leaf soil or peat soil can be added to the matrix

3、 Sowing

The seeds are generally picked after the weather turns cool in autumn. If you choose to sow in a hotbed, you can choose the middle and late March. If you sow in the open air, you need to delay the time. You can choose to sow the seeds evenly on the soil surface in April, which can be covered with a thin layer of soil, and then pay attention to the maintenance environment
