Key Points of Radermachera sinica Care and Analysis of Leaf Drop Causes

Radermachera sinica has been a relatively popular potted plant in recent years, because its symbolism is very good, and whether kept as an indoor potted plant or given as a gift, it is a good choice. As a foliage plant, the leaves of Radermachera sinica are emerald green and dripping with color, looking very full of life. So what are the key points of Radermachera sinica care? What is going on with the leaf drop?

1. What are the key points of Radermachera sinica care?

1. Choice of soil

For planting Radermachera sinica, it is generally more suitable to choose sandy soil with good looseness, good air permeability and good drainage. If growing it in a pot, you can also mix it yourself, using decomposed organic fertilizer, leaf mold, garden soil and so on in proportional amounts. After planting, the potting soil must be loosened on time to avoid soil compaction, which would prevent the roots from breathing.

2. Temperature and humidity

Radermachera sinica likes to grow in a warm, humid environment. The most suitable growing temperature is between 15 and 25 degrees Celsius, so in high-temperature summer weather, care must be taken very carefully, and appropriate cooling and adjustment must be provided. The rubber plant requires air humidity of no less than 70 percent. If the environment is too dry, its leaves should be sprayed with water to increase humidity.

3. Watering method

Watering Radermachera sinica depends on the growing season. Normally, watering does not need to be too frequent; watering once every two or three days is enough. If it is a high-temperature summer, then water evaporates relatively quickly, so more watering is needed, generally in the morning and evening. Of course, this does not mean allowing waterlogging and root rot to occur, so the degree must be controlled well. In winter, the number of waterings and the amount of water can be appropriately reduced.

4. Appropriate shading in summer

Radermachera sinica is a green plant that likes light, but it can also grow smoothly in diffused light. In winter, there is relatively little sunlight, and it can receive full sun, so it is suitable to move it outdoors for care. If it is summer, it is not recommended to place it on a balcony or other place with direct sunlight; it can be moved out in the morning and evening for a little sun.

5. Fertilization method

In spring, during the period when Radermachera sinica sprouts branches and buds, fertilization should be carried out. Generally, fertilize once a month, and a compound fertilizer is enough. Of course, the water from washing rice at home can also be used. In winter and summer, additional fertilizing is generally not needed; maintaining basic watering is enough.

2. What is going on with Radermachera sinica leaf drop?

1. Pests attacking the leaves: Radermachera sinica is very susceptible to scale insect infestation. If leaf drop occurs, you should check whether this pest is present. If it is found, you can wipe it with a cotton ball dipped in vinegar, and it generally takes effect within a few days.

2. Insufficient light: If Radermachera sinica is kept in a shady place for a long time, leaf drop will occur, because without sunlight the leaves cannot carry out photosynthesis. So in normal times, it can be appropriately moved to a balcony or a place with better light for care.

3. Poor ventilation: If indoor air is not circulating and there is long-term water shortage, leaf drop will also occur, so indoor air circulation should be maintained, and watering should be done well according to the above watering method.
