How to propagate Osmanthus fragrans

Osmanthus fragrans cutting propagation, easy to operate, more suitable for family use. The key of cutting propagation is the selection of cuttings, which is directly related to the survival rate of sweet-scented osmanthus trees. The branches of sturdy semi-mature branches can be cut as cuttings for tender cuttings. Mature branches can also be cut for hardwood cuttings. When selecting cuttings, avoid using overgrown branches, slender twigs, inner bore branches and diseased branches. The length of the cuttings is 8 cm to 12 cm. Cut off the tender shoots and leave 2 leaflets at the top. Cut and insert as you go, the depth inserted into the soil is 2 to 5 of the total length, and then the soil is compacted and watered once. Sweet-scented osmanthus trees like the cool environment with high air humidity, especially the cuttings that have not yet taken root, can not be too dry, can not bask in the sun, pay attention to sunshade within 1 month after cutting, it is best to build a double-layer awning, the height of the high shed is about 2 meters, and the height of the low shed is 60-70 cm. The direction of the sun in the high shed should also hang a curtain to shade the sun, and a sprayer should be used to spray water once or twice a day when the weather is dry. When the new root is 3 to 4 centimeters long, it can be transplanted. One or two weeks before transplanting, remove the Reed mats or grass curtains from the sun, so that the young seedlings can get exercise. Sweet-scented osmanthus striping propagation is divided into air striping and ground striping. First, air striping propagation can be carried out all the year round, but it is better before spring germination. Aerial striping propagation is more suitable for family potted plants. Usually before and after the Qingming Festival, 2-3-year-old branches are selected from excellent varieties of sturdy mother plants for circular peeling, the width of the incision is about 2 cm, take the bamboo tube and split it, and cover it with a layer of sandy moist culture soil, wrap the branches around the peeling place, wrap it in plastic sheeting, tie it with a belt, heal the wound after 1 month, and give birth to a new root in the incision cortex 3 months later. In October or the following spring, when the new root is 3-5 cm long, it can be cut off from the mother plant. Second, the ground pressing strip is also called Fu branch pressing strip or ordinary pressing strip. This method should be carried out in April ~ June or August ~ September (when the temperature is 25 ℃ ~ 30 ℃). Cut the skin 1cm long on the branch near the root, press it to the ground, pile 7-8cm thick soil on the injured branch, compacted, often watered to keep moist, and take root in about 3 months. In the following spring, it was cut from the mother plant and planted a new plant. If it is a potted plant, the branches that cut the incision can be pressed into another pot of soil and fixed, waiting for its roots to be cut off and transplanted.
