Prepare containers for hydroponics, wash them, disinfect them, and keep them for future use.
Choose in August when cutting, cutting two years of robust branches, no pests, length of about 10cm, cutting several
Arrange the cut branches in a hydroponic container. Put tap water or purified water in the container. Just use pure water. Wait for a few days, when the water inside becomes turbid, replace it with new water in time, and wait for these branches to sprout small roots
Waiting for about days, I saw that there were white spots on the branches, which proved that the branches sprouted small roots, and the hydroponics was successful for more than half of them. When they grow further, the roots can grow, and then wait for them to grow, and then they can be formally cultivated.
After the root system grows out, you can continue hydroponics, put it in a transparent glass bottle, change the water in it regularly, and drip nutrient solution. Can also be planted to pot soil, first placed in the shade, and so on to adapt to pay attention to the later maintenance.
