What is the reason why the purple leaves of osmanthus turn yellow?

1. The first reason why Lagerstroemia indica leaves turn yellow is that plants are undergoing normal metabolism. In this process, the leaves of plants will gradually turn yellow and fall off due to the natural consumption of nutrients, which is a normal phenomenon in the growth of Lagerstroemia indica.

2. Lagerstroemia indica has strong drought resistance. Soil moisture caused by too much water will make the root system difficult to absorb enough oxygen and weaken, so that nutrients can not be transferred to the leaves, resulting in yellow flowers on the leaves.

3. Powdery mildew is a disease that most plants will suffer during their growth, and Lagerstroemia indica is also an important infection object. The leaves of Lagerstroemia indica damaged by powdery mildew will wither gradually and eventually fall off, which seriously affects the growth of plants and the normal ornamental effect of Lagerstroemia indica.
