1、 Temperature discomfort

1. Reason: Rhododendron is sensitive to temperature. When the temperature is not suitable, its leaves may dry up. Specifically, whether it is too muggy or too cold, it will lead to this kind of phenomenon

2. Measures: in this case, the temperature must be regulated in time, and the most suitable range is between 15 and 30 degrees. Special attention should be paid to the extreme temperature in winter and summer

2、 Too much or too thick fertilizer

1. Reason: Rhododendron has a certain demand for fertilizer, but if the fertilization times are too many or the concentration is too high, it is easy to cause root burning, and then affect the absorption, resulting in dry leaves

2. Measures: if this is the reason, it is best to take off the basin, repair the root system, and then put on the basin. When fertilizing later, it is necessary to strictly control the amount and concentration, and then use it after dilution

3、 Disease causes

1. Some symptoms, such as leaf blight, root rot and so on

2. Measures: use corresponding agents according to the situation. At the same time, it is also necessary to ensure that the surrounding ventilation conditions are good, and the surrounding sanitary conditions also need to be paid attention to
