The rhizome is thin and yellow, and the adventitious roots are black-brown. The stem is slender, erect or oblique, slightly branched, purple in color, with nodes and fine white hairs, or nearly hairless. How is the cultivation of Red Shinners done?
Biological characteristics: It prefers shade and moisture and can tolerate cold. It grows well in loose, fertile, and well-drained soil.
Cultivation techniques: It can be propagated by division and seeds, with division being the main method.
During the period from winter when the plants die down to spring before they emerge, the rhizomes are excavated and divided into individual plants, with each plant retaining buds and adventitious roots.
During planting, the land is plowed, and high ridges of 1.3m wide are created, with holes spaced approximately 33cm apart in rows.
Two plants are planted in each hole, and the soil is compacted, and organic fertilizers such as manure and wood ash are applied, and finally covered with fine soil to level with the ridge surface.
Field management: After planting, weeding is done through cultivation, and fertilization is done three times a year.
The first time is shortly after emergence in March, the second time is in June to July, and the third time is during the period when the plants die down in winter. The dead stems and leaves are removed before fertilization, and soil is mounded for winter protection.
The first and second fertilizations mainly use manure, while the third time can be supplemented with wood ash or compost.
