Cuttings of jasmine bicolor are often made of nutritive soil, river sand, peat soil and other materials. Because it is difficult to obtain ideal soil in the family, it is recommended that you buy a good disinfected cuttings matrix, which can improve the survival rate for the novice cuttings.
Ordinary coarse river sand can also be used, but it should be washed with clear water before use. Try not to use the sea sand and saline alkali soil, which will affect the rooting of branches.
Generally, twigs are selected for cutting. In early spring or early autumn, the plants grow vigorously, and the branches of that year are cut as cuttings. When cutting branches, it should be noted that the distance between the upper cut and the last leaf is about 1cm, and the distance between the lower cut and the lower one is about 0.5cm, not too close to the branches and leaves, so as to avoid affecting the later rooting and germination.
Before cutting, the soil shall be soaked, and then according to the number of branches, the same amount of small holes shall be dug on the soil surface, and the branches shall be put into them, covered with soil and compacted. Pay attention not to break the branches in the soil during the operation. Then pour water, maintain a certain humidity, can be covered with plastic film to moisturize.
After cutting, it is difficult to control the temperature at 20-30 ℃, and it is difficult to root below 20 ℃. When the temperature is higher than 30 ℃, the incision is easy to be infected. The higher the temperature is, the greater the probability of decay is. In case of low temperature after cutting, measures shall be taken to keep warm.
Spray and moisturize in a timely manner, 3~5 times a day, and increase the number of times on sunny days. For those covered with plastic film to keep moisture, the plastic film shall be uncovered and ventilated every day.
Cuttings can not be separated from sunlight, sufficient sunlight is conducive to the accumulation of nutrients. However, the more abundant sunshine means the higher temperature, so it is necessary to shade in time, and gradually restore the light after rooting.
