Ramet propagation is generally carried out in spring and autumn. After digging out the roots, split them to ensure that each root has 2-3 root buds, which is conducive to survival. After that, planting should be carried out in time. During planting, holes about 15 cm deep should be dug, and the distance of each hole is about 30 * 15 cm. After planting the roots, cover them with 5 cm deep soil and compact them. If it has sprouted during planting, expose the sprout to the soil surface and water it in time
