reason
 In fact, the most important thing of hydroponic Anthurium is water. Most of the plant nutrients are obtained from water, and some rely on photosynthesis to accumulate nutrients. If water is not added in the hydroponic container in time, the nutrition in the water is insufficient, or the light is insufficient, any point will cause the leaves of Anthurium andraeanum to turn yellow.
 processing method
 Timely add water
 Check the water level in the hydroponic container frequently. When the water level is lower than 1/3 of the root, it is necessary to supplement water in time. As long as there is enough water in the hydroponic container, it is not necessary to sprinkle water on the leaf surface every day. If the leaves are dirty, gently wipe them with a wet rag.
 Add nutrient solution timely
 It doesn't matter how often to change the water for the hydroponic Anthurium andraeanum. The key is to grasp the content of nutrient solution in the water. As time goes on, water will be absorbed by plants, and the process of daily water addition has actually completed the step of water change.
 Therefore, in order to ensure sufficient nutrients in the water, a few drops of nutrient solution should be dropped into the container when adding water. As for the specific amount, you can be more flexible according to the growth of Anthurium andraeanum. At least two drops per time, and then observe the growth of the plant. If it is normal, it will remain unchanged, and if it is not growing well, it will be added appropriately.
 Supplement sunshine
 Compared with soil culture, hydroponic anthurium palmatum needs more sunlight. It needs 2-3 hours of direct sunlight every day (avoid direct sunlight at noon). More sunshine in winter can prevent its branches from turning yellow.
