What if the leaves of Rabdosia angustifolia turn yellow in winter

Rabdosia angustifolia is a kind of ornamental plant with high ornamental value, and its planting area is also very large in our country. When planting Rabdosia angustifolia, it will be affected by weather changes. Especially in winter, it is easy to have all kinds of problems. The yellow leaves of Rabdosia angustifolia is one of them in winter, so what should we do if the leaves turn yellow in winter? The following editor will give you a brief introduction, let's have a look!

1. Lighting control

In the process of growth, the demand for light is still relatively large. Sufficient light is needed to ensure the healthy growth of Rabdosia angustifolia, but in winter, not only the natural light time is short, but also its light intensity is relatively low. Therefore, at this time, the demand for light will be greater, so the lack of light in winter will easily lead to the yellowing of the leaves. Therefore, we should pay attention to create a bright light environment for it in winter to ensure that the grass can be fully exposed to the sun and reduce the yellowing of its leaves in winter.

2. Reasonable change of water

Rabdosia angustifolia is a kind of aquatic plant, and it is necessary to change water in the usual planting process. And many people think that in winter, the temperature is relatively low, so the possibility of bacteria breeding is relatively small. But it should be noted that if there is no change of water for a long time, then the water quality will gradually become turbid, the impact on the roots is very great, but also easy to cause leaves yellowing. Therefore, we should also pay attention to the change of water in winter and observe the changes in water quality. generally, we can change the water every two weeks or so. When changing water, also pay attention to its water temperature, not too low.

3. Temperature adjustment

In winter, the temperature is relatively low. If the ambient temperature of Rabdosia angustifolia is relatively low in winter, especially if it is lower than 5 degrees for a long time, then the plant is easy to be frostbitten, resulting in yellow leaf phenomenon. Therefore, in winter, we should pay attention to control the temperature and do a good job of heat preservation. Keep its temperature above 10 degrees, conditional heating equipment can be added to ensure the safety of Tongqian grass in the winter. Reduce the yellowing of Codonopsis lanceolata caused by low temperature.

4. Rational fertilization

Although the growth of Rabdosia angustifolia is relatively small in winter, the demand for nutrition will be less. But we should also pay attention to do a good job of fertilization in winter, if there is a lack of nutrition in winter, then it is easy to appear the phenomenon of deficiency yellow leaves. At the same time, we should also pay attention to control the amount of fertilizer, do not apply too much fertilizer, too much fertilizer is easy to lead to fertilizer damage, but also easy to cause fertilizer damage. Therefore, we should control the amount of fertilizer application and apply fertilizer reasonably according to the growth of Rabdosia angustifolia, so as to meet the growth and nutrition of Rabdosia angustifolia, and avoid fertilizer damage caused by excessive fertilization.

The above is a brief introduction to what to do if the leaves are yellow in winter. That's all for today's introduction. This article is for reference only. I hope it can help you all.
