What if the leaves of the rich tree turn yellow?

If the leaves of the rich tree turn yellow caused by improper watering, it is necessary to regulate and control the moisture; if it is caused by unscientific fertilization, it should be improved by watering more or changing the soil; if it is caused by diseases and insect pests, the leaves will be removed and sprayed with corresponding chemicals.

1. Irrational watering

The rich tree has little demand for water, and if it is not watered for a week, it will not cause the leaves to turn yellow and wither, but it is necessary to spray water on the leaves frequently, clean up the dirt on the leaves in time, and reduce the amount of water in a humid and poorly ventilated environment. Watering should be thoroughly watered, can not be watered dry and wet, which will also lead to the formation of dead leaves. If the watering is too much, the basin soil is too wet for a long time, resulting in lack of oxygen in the basin soil, making the roots rot and causing the leaves to turn yellow and fall off. When this kind of defoliation occurs in the rich tree, watering should be controlled immediately, fertilization should be suspended, and the soil should be often loosened to make the soil well ventilated. If the rich tree is dry and dehydrated, it will also cause the leaves to be dull and yellow, first the lower old leaves turn yellow and fall off, at this time need a small amount of watering and spraying, so that the rich tree will gradually recover and then turn to normal watering.

2. Unreasonable fertilization

For example, the rich trees have been de-fertilized for a long time, and there is a lack of nitrogen and other nutrients in the basin soil, resulting in thin leaves and thin and yellow leaves. In this case, the rich tree can be changed directly, into the new loose and fertile nutrient soil and gradually increase the application of thin mature liquid fertilizer or compound flower fertilizer. If the rich tree fertilizes too much, the new leaves will be thickened, and the old leaves will turn yellow and fall off. At this time, we should immediately stop fertilization, wash roots, increase the amount of water, make fertilizer flow out of the drainage hole at the bottom of the basin, or replace the basin soil.

3. Unreasonable lighting

The rich tree likes to be cool and moist, and if you put it in a high temperature place to let the strong light shine directly, it is very easy to cause scorched edges of new leaves or yellow leaves to fall off. At this point, it should be moved to a well-ventilated shady place in time. However, if the rich tree is overshadowed and placed in shaded places or places with insufficient light for a long time, it will also lead to yellow branches and leaves.
