Cut off the small hanging orchid can be hydroponic, but also can be soil culture, the operation is not only very convenient, but also the survival rate is very high. However, when hydroponic culture, we should pay attention to the leaves can not be put in the water, it is easy to appear rotten leaves. Not only that, it can also breed bacteria and affect plant growth.
Second, how to carry out hydroponics
1. Select seedlings: cut small orchids should use seedlings with air roots, so that the survival rate will be improved when hydroponic culture.
2. Select the container: choose the corresponding container according to the size of the plant, and it is recommended to use a transparent container for water culture, which is not only ornamental, but also can observe the growth degree of the root system. In addition, try to use a container with a bottleneck, which can hold the small orchid well.
3, the right amount of water: the water in the container can not be too much, to control the amount of water, the general water level is more than half or 1/3 of the root system of Cymbidium. The remaining root system can absorb oxygen very well, which is very helpful to its growth.
4. Daily maintenance: water should be changed frequently at the beginning of hydroponics, usually about 2 days. When the root system grows to 3-5 cm, an appropriate amount of nutrient solution can be added when changing water. Cut off the rotten roots and wash the inside of the container frequently.
