Osmanthus Tree Propagation Methods and Precautions
Cutting propagation is simple, fast in seedling growth, and quick to bloom, making it the fastest and simplest method. The Osmanthus branches recently inserted into the soil need proper care and management to successfully enter the rooting and germination stage. It is recommended to place them away from strong sunlight, such as in a shaded position; secondly, maintain moisture in a small space, and the soil should not accumulate water; finally, do not fertilize temporarily.
There are several propagation methods for Osmanthus, including grafting, sowing, and cutting propagation.
Grafting can improve the stability of the variety but is more difficult to operate; sowing propagation is from seedlings, which take about ten years to start blooming.
Thirdly, cutting propagation is simple, fast in seedling growth, and quick to bloom, making it the fastest and simplest method. Let's talk about how to perform cutting propagation.
Osmanthus Cutting Propagation Steps:
First Step, TemperatureAlthough Osmanthus has a certain cold tolerance, 15-28 degrees Celsius is the best growth temperature, which is the optimal growth temperature.
If propagation by cutting is done in summer, high temperatures will hinder the germination of new roots; if done in winter, low temperatures will damage the tissue of the branches; if done in autumn, dry weather will hinder the germination of new roots.
It is recommended to perform cutting propagation before new buds sprout in spring, which will result in cuttings with strong regenerative ability.
Second Step, BranchesAlthough Osmanthus plants have many branches and leaves, not all branches can be used as cuttings. If old branches or newly grown tender branches are chosen for propagation, it is prone to dehydration and withering, ultimately leading to propagation failure.
It is recommended to use one-year-old hard branches as cuttings, which can provide better moisture retention and regenerative ability, thus improving the survival rate of propagation.
The branches cut directly cannot be immediately used for cutting; they need to be pruned a second time to stimulate strong regenerative ability.
How to prune?
Firstly, keep the length around 6 centimeters and retain two small leaves; secondly, cut the root end at a 45-degree angle to facilitate water absorption; finally, immediately insert into the soil.
Third Step, SoilAlthough Osmanthus is planted in both northern and southern regions, it still prefers acidic soil. If alkaline soil is used for cutting, it will hinder the normal respiration of the branches, and over time, the roots of the branches will rot.
It is recommended to use neutral coarse sand or general acidic soil, or acidic vermiculite; among them, vermiculite has strong moisture retention and good breathability, which can greatly improve the survival rate of propagation.
Fourth Step, Care and TransplantingThe Osmanthus branches recently inserted into the soil need proper care and management to successfully enter the rooting and germination stage.
It is recommended to place them away from strong sunlight, such as in a shaded position; secondly, maintain moisture in a small space, and the soil should not accumulate water; finally, do not fertilize temporarily, only after new leaves and roots have sprouted and transplanting has been done.
The above-sharing of Osmanthus tree propagation methods and precautions is for the reference of green plant enthusiasts, hoping to solve your problems in green plant and flower management.
