What if the leaves of four Seasons osmanthus turn yellow?

1. Soil

This is a plant that likes slightly acidic soil, and once the soil it grows does not meet its requirements, its leaves may gradually turn yellow. If it is determined that this is the reason, we can consider using acid to adjust it. Generally, we use ferrous sulfate, which can be soaked in water and poured in the soil. Or we can change the basin and change the soil in which it lives, which is also a more direct way.

two。 Watering

If it is watered too much, it may cause its roots to soak in water, and the more serious ones will make its roots rot and indirectly cause its leaves to turn yellow. All we have to do at this time is to drive the water away. Generally speaking, we put it in a dry place is one way to let the water loss, put it in a ventilated place is another way, of course, the two are better together.

3. Fertilizer application

If we fertilize too much, it is also likely to cause its leaves to turn yellow, of course, this kind is also affected by the root, because it may be burned and indirectly affect the leaves. At this time, it is a wise way for us to choose to wash away the fertilizer with water.

4. Temperature

If the temperature is relatively low, it is also a reason that affects the growth of yellow leaves. Below ten degrees, it will grow yellow leaves. At this time, we should raise the temperature appropriately.

5. Transmission of light

When we raise it against the wall, we will find that some of the leaves on the branches have turned yellow, this is also because that part is out of contact with the sun, the solution is relatively simple, is to move it to the place where there is light.

6. Chlorosis

Chlorosis is also an important reason for the yellowing of its leaves, at this time we need to use drugs to treat, generally use carbendazim and other bactericidal substances.

7. Leaf alternation

In fact, there is a very natural reason why the leaves turn yellow, that is, the old leaves turn yellow in order for the new leaves to grow out. If this is the reason, we don't have to panic too much.
