1、 Plant cleaning

Select healthy potted plants. Pour enough water and then pull it out of the basin after two to three days. Then slowly remove the soil from the root and rinse with water. After washing off most of the soil, trim the roots and cut off the old and rotten roots

2、 Pick container

The containers for hydroponic culture are generally glass bottles. It should not be too high to avoid poor ventilation, resulting in poor plant respiration. Pour clear water into the bottle and insert the violets into the water. Two thirds of the roots should be immersed in the water, and one third of the water is used for breathing. In addition, it is best to use river water or spring water. If not, mineral water can be used. Tap water needs to stand for two days

3、 Daily maintenance

Daily maintenance is mainly to change water and add nutrient solution. The water change is generally once a week, but it should be adjusted according to the season. When changing water, add nutrient solution according to the recommended proportion of nutrient solution. Excess will affect the health of plants

4、 Precautions

1. Seasonal change: when it is hot in summer, water is easy to deteriorate and evaporate, and water can be added every morning. At the same time, change the water more frequently, usually once every two days. In addition, it is not suitable to expose the water cultured violet to the sun. In addition to being bad for the leaves, it will also increase the water temperature and cause great damage to the roots. In winter, because it is in the dormancy period, the time of changing water can be prolonged

2. Disease control: generally, aquatic violets will not suffer from pests, but may be infected. Timely change the water for the infected plants and apply the medicine according to the disease phenomenon
