Propagation methods of Osmanthus fragrans

A year of autumn, sweet-scented osmanthus fragrance, is now in the sweet-scented osmanthus blooming season, sweet-scented osmanthus we all know, when the flowers are full-bodied, fragrant ten miles, is also one of the common plants in our life. So do you know how sweet-scented osmanthus propagates? Let's take a look at it.

1. Sowing and reproduction

The seeds of sweet-scented osmanthus can be sowed in both spring and autumn. Before sowing, the ground should be adjusted, the basic fertilizer should be applied, and the navel of the seed should be placed on the side when sowing, so as not to bend the radicle and young stem of the seed and affect the growth of seedlings in the future. After sowing, cover some fine sand, cover grass blankets, pay attention to shade and moisturize, and often keep the soil moist, so that seedlings can emerge in the same year. The seedlings found in seeds are called seedlings, but it takes at least more than ten years to see them blossom, so sweet-scented osmanthus is generally used to cultivate seedlings.

2. Cuttage propagation

Sowing and reproduction takes too long, so you can use cutting propagation, which takes only four years to blossom, which is much shorter than the time required for sowing and reproduction. Before sprouting in spring, cut off the annual branches with a length of about 5-10 cm, cut off the leaves at the lower end and retain 2-3 leaves in the upper part. Then cut it on the culture soil and do shading treatment in time after cutting. pay attention to keep the temperature at 20-25 degrees and take root and transplant in two months.

3. Striping propagation

In addition to cutting, you can also choose striping control. In spring or early summer, choose a sturdy low-dry mother plant, take its lower branches for 1-2 years, select the parts that are easy to bend, and cut them with a sharp blade to reach the woody part of the branch. in pressing it into 3-5 cm of soil, the branches are fixed concave, leaving only the top of the branches and leaves outside, and pay attention to keeping the soil moist. After the branches take root in autumn, they can be cut off and transplanted.

4. Grafting propagation

The grafted rootstocks can choose privet or ash. Before sprouting in spring, about 10-12 cm cuttings are selected from 1-2-year-old trees and grafted after cleaning and disinfection. Cut off the leaves of the lower cuttings, leaving only 3 to 5 upper leaves. The survival rate of oblique chips is high. Remember to cut oblique chips at 1/3 of the rootstock.
