Cultivation and conservation:

The aboveground stems of Polygonatum odoratum are single and unbranched, and the stems and leaves are smooth and green; Underground tubers are developed, dark in color and uneven in surface. In early spring, drooping small white flowers bloom from the axils of leaves. At this time, if there is too much water supply, the buds will fall off before opening. Using soft soil is beneficial to tuber propagation. Although tubers have the ability to retain water, when the stems and leaves on the ground wither in winter, it is necessary to keep the soil moist slightly, so that it will grow normally next year.

It is advisable to divide large underground stems, as long as each piece has obvious bud points, it can survive. After cutting, put it in a ventilated place for an hour or two, and then implant it into the basin after the incision is dry. Don't bury it too deep when planting, just let the upper part of the tuber be flush with the soil surface.
