How to Propagate Variegated Star Jasmine by Layering? Detailed Method and Steps
For layering propagation of variegated star jasmine, you can choose either mature branches or new tender shoots. Generally, in spring it is best to choose mature branches for layering propagation, while in summer, new tender shoots are used for propagation.
When layering, press the branches of variegated star jasmine that have root fibers into the soil, water and fertilize appropriately, and the branches will gradually take root. Wait until the roots become thick and strong and the branches have grown new buds; at this point, you can separate the rooted branches from the mother plant and replant and care for them.

Cutting Propagation of Variegated Star Jasmine
Cutting propagation is a commonly used propagation method for variegated star jasmine.
Propagating variegated star jasmine by cuttings is relatively simple. Cuttings can be taken in all four seasons, but spring and autumn are the best times for cutting propagation. Summer also works, but the branches of variegated star jasmine are prone to rotting. If you want to take cuttings in winter, certain heating measures need to be taken. When taking cuttings, choose a suitable container and place a cutting medium made of perlite, peat, and vermiculite in a certain ratio. Cut branches of suitable length, keep 2 to 4 leaves, and insert them into the soil. After cutting, maintain a suitable temperature and pay attention to shading; after about 15 days of care, they will take root.
Pay attention to observing the growth condition of variegated star jasmine to avoid death from disease.
Overall, propagating variegated star jasmine by cuttings gives the best results. Cutting propagation has a shorter cycle, faster growth, and is relatively easy to root. Moreover, propagating variegated star jasmine by cuttings allows for large-scale propagation of more plants.
Layering Propagation of Variegated Star Jasmine
For layering propagation of variegated star jasmine, you can use either old branches or tender branches.
Old branch layering can be done in spring, and tender branch layering can be done in summer. Press the branches of variegated star jasmine into the soil and wait for them to gradually take root. When the roots have grown out and the new buds have grown to a certain extent, separate them from the mother plant and replant them.
However, relatively speaking, layering propagation is slightly more difficult than cutting propagation.
Tissue Culture of Variegated Star Jasmine
Tissue culture is also a propagation method for variegated star jasmine. However, compared to cutting propagation and layering propagation, tissue culture is more difficult and has a lower success rate, so the tissue culture method is not widely adopted.
Cutting Propagation of Variegated Star Jasmine
Variegated star jasmine can be propagated by cuttings in any season of the year. The rooting rate in spring and autumn can reach over 98%. Cuttings taken in summer are prone to rotting for some branches that are too tender, but branches that have reached semi-lignification can all take root and survive.In addition, variegated star jasmine can also be propagated by layering. Generally, old branch layering is done in early spring, and tender branch layering in summer, burying about 3 cm in soil. Both nodes and internodes can take root to form a new plant, but the propagation rate of layering is rather slow and requires a large amount of labor, making it difficult to apply in large-scale production.
The rapid propagation technology for variegated star jasmine through tissue culture has been completed. Our tissue culture laboratory has established a corresponding rapid propagation tissue culture system (see another article). Variegation can appear during the tissue culture process, and the ornamental traits are stable.
Based on both growth and ornamental value considerations, the cultivation of variegated star jasmine can appropriately separate seedling production, plant cultivation, and finished nursery stock cultivation. That is, under the most suitable environmental conditions such as semi-shade and loose, fertile cultivation substrate, mass propagation and early-stage plant cultivation are carried out. When the plants reach 20 cm in length and have many branches, they are moved to stronger light conditions for cultivation to achieve brilliant leaf color.
