Many people will find some leaves yellowing in the process of planting, so what is the yellowing of the leaves of the rich tree? Teach you six correct remedies!

I. the reason for the yellowing of the leaves of the rich tree

1. Improper watering

Too little watering will cause the leaves to turn yellow. The rich tree is native to Xishuangbanna in Yunnan and likes the warm and humid climate. If too little watering will lead to yellowing of leaves, too little watering will lead to wet soil surface and dry bottom, which will affect the nutrient absorption of rich tree roots, and will lead to leaf withering and yellowing and even shedding from bottom to top.

Too much watering can also lead to yellowing of leaves. Too much watering will cause the roots of the rich tree to be soaked in the too wet soil environment for a long time, which will easily cause the rhizome to rot, which will lead to the withering and yellowing of the leaves from the bottom to the top, and even the death of the whole plant.

two。 Improper lighting

Too much light will cause the leaves to turn yellow. Although the rich tree likes the sun, it can not stand the exposure of the sun. The scorching sun will increase the surface temperature of the leaves, accelerate the loss of water in the leaves, and burn the leaf tissue, thus causing the leaves to turn yellow.

Too much shade can also lead to yellowing of leaves. The rich tree likes the light. If the rich tree is sheltered for a long time, it will cause the leaves to be dim and finally yellow and fall off.

3. Improper nutrition

Malnutrition can lead to yellowing of leaves. In the process of planting rich trees, we can apply fertilizer properly, pour rice water or special ingredients, otherwise it will easily lead to malnutrition and yellowing of leaves.

Too much fertilizer can also lead to yellowing of leaves. Excessive fertilizer can burn the rhizome of the plant, causing damage to the rhizome and yellowing leaves.

4. Improper temperature

Too high temperature will cause the leaves to turn yellow. Rich trees like a humid environment, high temperature will lead to transpiration is too strong, water loss is too fast, resulting in dry leaves yellowing.

Too low temperature can also lead to yellowing of leaves. The rich tree is not resistant to freezing. Once the temperature is lower than 16 °, the outdoor tree should be moved indoors. Once the temperature is lower than 10 °, it is easy to cause plant death.

5. Influence of diseases and insect pests

Rich trees can also cause their leaves to turn yellow when they are affected by diseases and insect pests. The common diseases of rich trees are leaf spot disease, common pests are red spiders, shell insects and so on.

6. The branches and leaves are too dense

The adaptability of the rich tree is strong, the vitality is also very exuberant, and the growth rate of branches and leaves will be accelerated in a suitable environment. If the leaves are too dense, the inner leaves will not be able to absorb sunlight, and ventilation will also be affected, which will lead to yellowing and sagging of the leaves of the plant.

Second, how to remedy the yellowing of the leaves of the rich tree

1. Replenish water and turn over basins in time

Replenish water in time when watering too little, first moisten the surface soil and then slowly add water, subject to penetration. Turn the basin in time when watering too much, loosen the soil, make good ventilation, and dry the over-moist soil quickly.

two。 Move the plant to the semi-shade.

Whether it is a rich tree plant whose leaves are yellowed due to overexposure or lack of sunlight, the best way is to move it to a semi-shade and water it properly to keep it ventilated. Plant recovery takes a process, after a period of time, the yellowing leaves will fall off and new leaves will grow out.

3. Root and change soil

If the root of the rich tree decays due to excessive fertilization, the rotten part of the plant should be cleaned up and replanted.

4. Cooling and increasing temperature

In summer, when the leaves turn yellow due to high temperature, move the plant to a cool place and sprinkle water to cool it. The rich tree should be moved indoors in time in winter to avoid frostbite.

5. Spray medicament

In view of the diseases and insect pests of the rich trees, we should choose the corresponding agents, kill insects and sterilize them, and do a good job of killing insects.

6. Timely pruning

For the rich tree plants that grow too thickly, we should take measures to prune the branches. Don't be reluctant to cut them off. Proper pruning is to make the plants grow better.
