Evergreen pruning can be hydroponically cultured, it is more suitable to grow in a humid environment, hydroponics can better meet this condition. In addition, hydroponics is clean and sanitary, so it is not suitable for diseases and insects. But the strict control of water quality, but also moderate use of nutrient solution, to avoid injury to the root.
1. Cutting branches: select healthy and robust branches from Rohdea japonica, with a diameter of more than 1 cm. Cut a section 5-8 cm long, and keep the stem nodes on it. The position of the stem node will take root, without which it can't be raised.
2. Disinfection treatment: apply potassium permanganate solution to the bottom of the cut branches. The concentration of the solution should not be too high. It needs to be mixed with water into pink to avoid damage to the branches. After that, we should put it in a cool and ventilated place, and then we can do hydroponics.
3. Container selection: the size of the container should be moderate, and it is better to choose a thin transparent glass or glass bottle. In this way, it is more conducive to its finalization, and at the same time, it can observe the situation inside. Pour two thirds of the water into the container. The water quality is good. The tap water can only be used after a few days.
4. Hydroponics: put the bottom of the branch into the hydroponics container, so that the stem nodes are flooded. Change the water every four days and add a little nutrient solution. After rooting, the frequency of water change can be reduced, and once a half month in summer. At the same time, we should control the amount of water so that some roots are above the water level.
