What to do if the leaves of Osmanthus fragrans turn yellow

1. Soil

This is a plant that likes slightly acidic soil. Once the soil in which it grows does not meet its requirements, its leaves may gradually turn yellow. If it is confirmed that this is the reason, you can consider using acid to adjust it. Generally, we use ferrous sulfate. Just soak it in water and pour it into the soil. Or we can change the pot and the soil in which it lives, which is also a more direct method.

2. Watering

If you water it too much, its roots may be soaked in water. In serious cases, its roots may rot, which may indirectly cause its leaves to turn yellow. What we need to do at this time is to drive away the water. Generally speaking, putting it in a relatively dry place is one way to let the water drain away, and putting it in a ventilated place is another way. Of course, it is better to do both together.

3. Fertilization

If we apply too much fertilizer, it is also likely to cause its leaves to turn yellow. Of course, this is still affected by the roots, because it may be burned and indirectly affect the leaves. At this time, it is a wiser approach for us to choose to use water to flush away the fertilizer.

4. Temperature

If the temperature is relatively low, it will also cause the leaves to turn yellow. If the temperature is below ten degrees, the leaves will turn yellow. At this time we need to increase the temperature appropriately.

5. Light transmission

When we grow it against the wall, we will find that the leaves on some branches have turned yellow. This is because that part is not exposed to sunlight. The solution is relatively simple, which is to move it to a place with light.

6. Chlorosis

Chlorosis is also an important reason why its leaves turn yellow. At this time, we need to use pesticides to treat it. Generally, bactericidal substances such as carbendazim are used.

7. Leaf Alternation

In fact, there is a very natural reason for the leaves to turn yellow. That is, the old leaves turn yellow and fall off so that new leaves can grow. If this is the reason, there is no need to panic.
