1、 Hydroponic method

1. Plant selection: besides soil culture, iris can also be maintained by hydroponic culture, which is also one of the methods of maintenance and culture. Before hydroponic culture, we should select appropriate plants, preferably vigorous plants in the growth period, and the root system should be fully developed, so that the survival rate of such plants will be higher

2. Treatment of plants: before hydroponic culture, the soil attached to the roots shall be removed and cleaned in clean water. The dead leaves shall be removed, the rotten roots and old roots shall be properly trimmed, the potassium permanganate solution shall be prepared, the roots of the plants shall be soaked in for disinfection, and the roots shall be fished out after about 10 minutes. After disinfection, put it aside and dry it slightly

3. Prepare containers: after processing the plants, you can prepare appropriate containers. Choose a transparent glass container. Put the plants in and add an appropriate amount of water for hydroponic culture

4. Later maintenance: after hydroponics in containers, pay attention to maintenance and management in the later stage, put it in an astigmatic environment, properly contact with soft light, change water regularly, keep clean, and add nutrient solution dropwise

2、 What about hydroponic rotten roots

In the process of iris hydroponic culture, we should pay attention to prevent the problem of rotten roots. After the rotten roots occur accidentally, we should take out the plants, trim the rotten roots, and cultivate and maintain again after disinfection and sterilization
