1. Water

Unclean water is a big reason, because once there is a problem with the quality of water, it is easy to rot its roots and turn its leaves yellow. We can change the water every ten and a half days in summer, but we don't need to change it every five and a half days in summer. If a friend who hasn't changed water for a long time turns yellow, change it quickly

2. Nutrients

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

Over nutrition is also a major influencing factor, because too much nutrient solution is added to it at ordinary times and is not used by it. Therefore, some microorganisms will also grow in it. At this time, they will rob the nutrients of plants. On this basis, if we do not change the water, we will find that its roots are full of sticky things

3. Light

Light is one of the great influencing factors. We usually put it in a place with light, otherwise it is likely to have only yellow leaves. In winter, we should 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 sunbathing takes an hour. In addition, you can't get too much sun in summer, so just put it where the sun can't be directly exposed

4. Ventilation

Ventilation is also something to do, because better air is very effective for its growth. Generally, it is easy for yellow leaves to emerge without putting it in a ventilated and bright place

5. Temperature

It is necessary to control the temperature, because it is afraid of cold, and only warm places can make it grow better, so our placement should be determined. Especially in the north, the temperature is relatively low, it can not survive the winter safely, and yellow leaves are also reasonable. Therefore, we need to get a cover to cover it and maintain sufficient temperature. It can be adjusted to 10 ℃ - 25 ℃ in spring, which can make it grow better
