Why Is Your Radermachera Sinica Dropping Leaves? Latest Cause Analysis

Radermachera sinica (China doll) is a very common potted plant in our daily lives. Because its name carries an auspicious meaning, it is welcomed by many people. It is very suitable for growing at home, in offices and other places. However, when growing Radermachera sinica, people often encounter the phenomenon of it dropping leaves. So what exactly is going on when Radermachera sinica drops its leaves? Today the editor will briefly introduce this to everyone. Let's take a look below!

1. Improper watering

Improper watering very easily causes Radermachera sinica to drop leaves. Although Radermachera sinica has certain water requirements, its tolerance for waterlogging is relatively poor. So if it is watered too much, then Radermachera sinica may develop root rot as a result, the roots cannot breathe or absorb nutrients, and the leaves will turn yellow because of this. But you also cannot stop watering entirely. If the soil is too dry, then the leaves will turn yellow and dry up due to lack of water. So if excessive watering causes the leaves to turn yellow, take the plant out promptly, cut off the rotten roots, replant it, and reduce the humidity. If the watering is too little, then water it promptly and keep the soil in a slightly moist state.

2. Unsuitable temperature

Temperature is also very important for the growth of Radermachera sinica. And unsuitable temperatures very easily cause Radermachera sinica to drop leaves as well. The suitable growing temperature for Radermachera sinica is around 25 degrees. If the temperature goes beyond the range of 5-30 degrees, then the leaves will turn yellow and fall because they cannot adapt to the temperature. Therefore we should pay attention to controlling the temperature according to seasonal changes. For example, in summer, do a good job of cooling to avoid excessively high temperatures causing the leaves to lose water and wilt. Similarly, in winter, strengthen insulation to avoid low temperatures causing cold damage to Radermachera sinica.

3. Lighting reasons

Radermachera sinica's demand for light is still quite high, but it also has a certain tolerance for shade, while its ability to tolerate strong light is relatively poor. So when growing Radermachera sinica, if its leaves are exposed to direct strong light without proper shading work being done, then the leaves are easily scorched. But it also cannot be kept in weak light for a long time. In a weak-light environment, Radermachera sinica cannot carry out photosynthesis, and it will also turn yellow due to a lack of nutrients. Therefore, when providing sufficient light, we should pay attention to controlling the light intensity well, and do a good job of shading when the light is too strong. In winter, artificial supplementary lighting should be carried out, and it should not be kept in a dark, weak-light environment for a long time.

4. A normal phenomenon

Sometimes Radermachera sinica dropping leaves is also a normal phenomenon. Because Radermachera sinica also needs to carry out metabolism, and when it carries out metabolism, dropping leaves is just one of the phenomena. This is because the nutrient synthesis rate of the old leaves on Radermachera sinica declines, and the nutrients synthesized are not as much as what they consume themselves. In order to provide growing space for new leaves, the plant will automatically shed the old leaves. So if all the leaves that fall are old leaves, then we do not need to worry. After the old leaves have finished falling, new leaves will grow.

The above is a brief introduction to what is going on when Radermachera sinica drops leaves. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
