What to do if the leaves of hydroponic copper coin grass turn yellow

1. Water

Unclean water is a big reason, because once there is a problem with the water quality, it is easy for its roots to rot, causing its leaves to turn yellow. Generally, we should remember to change the water every three to five days in summer and every ten days to half a month in winter. Please note that changing the water does not mean getting rid of all the water. We only need to replace two-thirds of it with new water. If you haven't changed the water for a long time and the leaves turn yellow, change it quickly.

2. Nutrients

Of course, it is also possible that the leaves turn yellow due to lack of nutrients, so we need to add nutrient solution when changing the water to alleviate this symptom. At this time we need to shake it gently, so that the water will contain more oxygen, and the roots will grow much faster.

Excess nutrition is also a major influencing factor. Because too much nutrient solution is usually added to it and is not fully utilized by it, some microorganisms will also grow in it, and at this time they will steal the nutrients from the plants. On this basis, if we do not change the water, we will find that its roots are covered with sticky things.

3. Light

Light is one of the major influencing factors. We usually have to put it in a well-lit place, otherwise it will most likely have only yellow leaves. In winter we have to put it outside the house so that it can be exposed to light. Generally, the light at ten o'clock is better, and the time span of sun exposure needs one hour. In addition, it should not be exposed to too much sunlight in the summer, so it is better to place it where it cannot be directly exposed to the sun.

4. Ventilation

Ventilation is also something that needs to be done, because better air is very helpful for its growth. If it is not placed in a ventilated and well-lit place, yellow leaves will easily appear.

5. Temperature

It is necessary to control the temperature, because it is afraid of cold, and it can only grow better in a warm place, so we have to determine the placement of it, especially in the north where the temperature is relatively low, it cannot survive the winter safely, and it is reasonable for the leaves to turn yellow, so we need to cover it with a cover to maintain a sufficient temperature. In spring, you can adjust the temperature to between 10℃-25℃, which will make it grow better.
