Generally speaking, cutting in spring and autumn gives a high survival rate. Pay attention to the growing medium as well: mix potting soil, leaf mold and sandy soil, then add some perlite. As for the flower pot, don't use one that is too large. Don't choose branches that are too old, and don't choose branches with pests or diseases; once selected, remove most of the leaves. Next, pour the growing medium into the container, then use a tool to poke holes. Then, insert the branch and firm the soil around it. After that, water thoroughly and cover with plastic film. After about half a month to twenty days, roots will form.

1. Timing

If grown indoors, it can be done all year round. However, doing it in spring and autumn will have a higher success rate than in the hot summer or the severe cold of winter.

2. Growing Medium

You can mix commercially sold potting soil, leaf mold and sandy soil together; the effect is quite good. You can also add some perlite to it, which will give it better water permeability.

3. Container

The requirements are not too high; just don't make it too large, generally 15 to 20 caliber.

4. Branches

Don't choose branches that are too old or have pests or diseases; choose fresh, healthy branches, about 10 cm long. Then wait for the cut to dry, and cut off two-thirds of the leaves on it. In addition, if there are flower buds or fruits, cut them off too. This can effectively reduce evaporation.

5. Inserting the Branches

Pour the growing medium into the flower pot, then use scissors, a bamboo skewer, or chopsticks to poke holes. Space each about 6 cm apart, with a depth of 2 to 3 cm. Then, insert the branches and press the surrounding soil flat.

6. Later Management

After all the above steps are done, water thoroughly, then cover with a layer of plastic wrap. As for light, indirect light is enough. Keep the temperature at 18 to 20°C. After about half a month or twenty days, roots will grow. If you observe no rotting or wilting, it means they have survived. After 30 days, they can be transplanted. However, because their recovery is relatively slow, bring more soil along.
