The characteristics and reproduction of the knot
The knot is a deciduous shrub, usually about 1 meter high, and the shoots often have tridentate branches. The leaves are oval-shaped and broadly lanceolate. The flowers are head-shaped, with branches on top, perianth tube-shaped, apex 4-lobed, yellow. After the fall leaves, a branch of buds was planted on the branches and leaves were opened in March of the following year. Branches are soft, tough, and bent to knot, so they are also called "knotted trees." The knot is suitable for garden cultivation or pot appreciation. The knots are usually propagated using cuttings, battens or ramets. Cutting propagation is generally suitable for the Meiyu season. The cutting length is about 15 cm. It is best to use a knife to open a little at the lower end of the cutting, and insert a small stone to increase the contact surface with the substrate. It can promote rooting and insert into the sand. About 1/2, shading or semi-shadow, it is easy to survive. Batten propagation can be carried out at the root neck purlin. The base is usually wounded in early spring and then covered with soil, and the planting can be cut in the coming year. The propagation of ramets can be carried out after defoliation and before germination, and it can also reproduce after flowering. China Agricultural Network Editor
