In the south, medicinal plants are planted in a large area, or vertical greening and fragrant environment are widely cultivated in the courtyard. In the past, the north could only plant in boxes and make bonsai, which needed to spend the winter indoors or in cellar. According to the author's trial planting, it can also be cultivated in the open field in cold areas. The main points of management are as follows:

First, planting honeysuckle Xi Yang also endure yin, do not choose the soil. According to 60 cm plant distance and hole depth of 40-50 cm, mix agricultural fertilizer and hole soil well, stretch and implant the root system, and pour water through it.

Second, when the height of the plant is 30 cm, the pole is tied up 10 cm away from the root, and then the vine is fixed upward with the spread of the branch. To prevent the branches from falling and tangling to affect the growth. In that year, it can grow to 3-4 meters, so the pole should be high, fixed and firmly fixed, and the wire or thin wooden pole should be pulled across the pole to evenly fix the vine to facilitate ventilation and lighting.

Third, pruning the new shoots when 30 cm high, promoting lateral branches, and 50 cm high lateral branches, and promoting three times of branches. after late June, they will no longer be pruned except for long branches and weak branches to ensure the yield of flowers. From then on, the vine branches should be retracted every year to prevent the lower part from being bald, pay attention to control the long branches, and cut off the dense, old and sick branches.

Fourth, fertilizing honeysuckle grows rapidly and has a large number of branches and leaves, and its flowers are frozen from the middle of June, which consumes a lot of nutrition. compost and stable manure should be applied in the rhizosphere in autumn and early spring, and dilute liquid fertilizer should be applied frequently after sprouting and picking flowers.

Put it on the mat or in the basket, spread about 1 cm, eight or nine layers. Do not turn it before drying, let alone touch it with your hands, otherwise you will get blackened and move indoors in case of sun drying or rain, but do not store it in piles and dry it on a sunny day or the next day.

6. Select 1-2-year-old strong branches in spring, the two segments are one section, the lower part is oblique at 1 cm below the node, and the upper part is cut flat at 1.5 cm above the node, the cut mouth should be smooth. Insert it with a stick on the finished bed soil and water it thoroughly to buckle the shed. In summer, one-year-old sturdy branches that have been semi-lignified can also be taken, such as cuttings, but with moderate shade.

Seventh, overwintering cold honeysuckle can not be frozen to death, after the shelf in late autumn, less can be set up, more branches will be flat covered with water, covered with sawdust and other mulch 15cm, you can safely survive the winter. The following year, "May Day" lifted the cold protection, buckled the shed, gradually uncovered the film at night or in the sun, and then removed the shed and grew naturally more than ten days later.
