Reproduction methods and precautions for osmanthus trees (how to propagate osmanthus by cuttings quickly and with high survival rate)

There are many ways to propagate osmanthus: grafting, sowing and cutting.

Grafting propagation can improve the stability of the variety, but it is more difficult to operate; sowing propagation is a seedling, which needs to be cultivated for about ten years before the flowers can be seen blooming.

Third, cutting propagation is simple to operate, and it can quickly form seedlings and bloom. This method of propagation is the fastest and simplest. Next, let's talk about how to carry out cutting propagation?

The operation steps of osmanthus cutting propagation:

Step 1, temperature

Although osmanthus has a certain degree of cold resistance, it grows best at 15 to 28 degrees Celsius, which is the suitable temperature for growth.

If cuttings are used for propagation in summer, high temperatures will hinder the germination of new roots; if cuttings are used for propagation in winter, low temperatures will freeze the branch tissues; if cuttings are used for propagation in autumn, dry climates will hinder the germination of new roots.

It is recommended to carry out cutting propagation before the new buds sprout in spring, so that you can get cuttings, that is, branches, with strong regeneration ability.

Step 2: Branches

Although the osmanthus plant is luxuriant, many branches cannot be used as cuttings. If you choose perennial old branches or newly grown tender branches for cutting propagation, it will easily lose water and wither, which will eventually lead to propagation failure.

It is recommended to choose hard branches that have grown for more than one year as cuttings, which can bring better moisture retention and regeneration capabilities, thereby improving the survival rate of reproduction.

The branches that are cut directly cannot be used for cuttings immediately, and they need to be pruned again to stimulate their strong regeneration ability.

How to perform pruning?

First, control the length to about 6 cm, while retaining two small leaves; secondly, trim the roots into a 45-degree oblique shape to facilitate water absorption; finally, insert it into the soil immediately.

Step 3: Soil

Although osmanthus is grown in both the north and south, it still prefers acidic soil. If alkaline soil is used for cuttings, it will hinder the normal breathing of the branches, and the roots of the branches will rot over time.

It is recommended to use neutral coarse sand, or generally acidic soil, or acidic vermiculite; vermiculite has strong moisture retention and good air permeability, which can greatly improve the reproduction survival rate.

Step 4: Maintenance and transplanting

The osmanthus branches that have just been inserted into the soil need to undergo reasonable maintenance and management before they can successfully enter the stage of rooting and sprouting.

It is recommended to place it away from strong light, such as in a shady location; secondly, keep the small space moist, and do not allow water to accumulate in the soil; finally, do not apply fertilizer for the time being, and wait until new leaves and new roots sprout, and after transplanting, before applying fertilizer and maintenance.
