1、 Reasons for rotten roots

1. Do not change the water for a long time: when the daffodils are watered, the water quality must be kept clean and clean. If the unclean water quality is provided or the water is not changed for a long time, it will cause a lot of impurities in the water and harm the root, resulting in the pollution of the root of the daffodils and the root rot

2. Too much nutrient solution: when hydroponically culturing daffodils, it is necessary to add nutrient solution appropriately. However, once too much is added, the root will be difficult to bear, causing fertilizer damage. If it is not controlled, it will lead to root rot

3. Too high temperature: daffodils like a cool climate and can't stand high temperature. When the temperature in the growth environment is too high, it will also easily cause root rot

2、 How

1. Cut off rotten roots: after finding the signs of rotten roots in daffodils, take the plants out of the container, prepare a sharp knife, cut off the rotten roots, leaving only healthy roots, and then put them in a cool place to dry

2. Re hydroponic culture: the roots can be re hydroponically treated. The water quality should be selected, and the tap water can be dried

3. Regular water change: pay attention to the later maintenance after hydroponic culture, change water regularly to keep the water quality clean, add nutrient solution reasonably, pay attention to the concentration, and keep the surrounding temperature at about 10-15 ℃
