1、 Water change frequency

During the water culture of lilies, the water quality should be kept clean at all times, so the frequency of changing water becomes very important. Generally, when the temperature is high in summer, the water should be changed every 2-3 days; When the temperature is slightly lower in spring and autumn, the water can be changed every 3-5 days; The temperature in winter will be very low, and the water change can be carried out once a week

2、 Precautions

While changing the water, you need to wash the root of the plant with clean water to avoid sticky attachments after a long time. In addition, the hydroponic container should be thoroughly cleaned to ensure that the inner wall of the container, the root of the plant and the water quality are in a clean state. If necessary, the container can also be properly disinfected

3、 Other maintenance

1. Sunshine: during water culture, the plant should meet the requirements for light. It should receive certain light every day, and about 6 hours is the best. Be careful not to keep it in the dark for a long time

3. Nutrient: water nutrition also needs to add nutrients. Nutrient solution can be added appropriately according to the growth state of the plant, as long as the nutrient solution with too high concentration is not applied to it
