The seeds of Sweet osmanthus can be sown in spring or in autumn. Before sowing, the soil should be adjusted and the base fertilizer should be applied. When sowing, the navel should be placed on the side to prevent the radicle and young stem of the seeds from bending and affect the growth of seedlings in the future. After sowing, cover the surface of the seed with a layer of fine sand, then cover it with straw felt, pay attention to shading and moisturizing, and often keep the soil moist, so that the seedlings can emerge in the same year.
Before sprouting in spring, use one-year robust branches, cut the branches about 5 to 10 cm long, cut off the lower leaves, keep 2 or 3 leaves on the upper part, and insert them on the culture soil. After cutting, water or spray water in time, and cover the shade, keep the temperature at 20 to 25 ℃, take root after about two months, and then transplant them.
In spring or early summer, choose a relatively thick and low dry mother tree, select the lower 1-2-year-old branches, select the parts that are easy to bend, cut them with a sharp edge ring to reach the woody parts of the branches, then press them into the soil 3-5cm deep, fix the branches, leave only the top of the branches and leaves outside, pay attention to keep the substrate moist, and then cut them off after the roots of the branches in autumn. The mother plant has been transplanted for maintenance.
