In fact, the most important thing for hydroponics is water. Most of the plant nutrients are obtained from water, and some of them are accumulated by photosynthesis. If the water is not added in time in the hydroponic container, the nutrition in the water is insufficient, or the light is insufficient, any point will cause the leaves of Anthurium andraeanum to turn yellow.
Check the water level in the hydroponics container frequently. When the water level is lower than 1 /3 of the root, make up the water in time. As long as there is enough water in the hydroponic container, it is not necessary to sprinkle water on the leaf every day. If the leaf is dirty, wipe it gently with a wet rag.
It doesn't matter how much time is needed to change the water in hydroponic culture. The key is to grasp the content of nutrient solution in water. As time goes on, the water will be absorbed by the plants. The process of daily water adding has actually completed the step of water changing.
Therefore, in order to ensure sufficient nutrients in the water, when adding water to the container, drop a few drops of nutrient solution. As for the number of drops, you can be more flexible according to the growth of red palm. Drop two drops at least each time, and then observe the growth of the plant. If it is normal, it will remain unchanged, if it is poor, it will be added appropriately.
Compared with soil culture, hydroponic Anthurium andraeanum needs more sunlight. It is necessary to keep the direct sunlight for 2-3 hours every day (avoid the direct sunlight at noon). More sunlight in winter can prevent the branches and leaves from becoming weak and yellow.
