What about yellow leaves?

The appreciation value of dripping Guanyin mainly lies in its lush and verdant leaves. When watering or air humidity is high, water droplets will drop from the edge of the leaves, which is very likable. Once dripping Guanyin appears the phenomenon of inverted leaves, yellow leaves, and drooping leaves, the overall shape of Dishui Guanyin will be affected, thus affecting the ornamental value. Therefore, it is necessary to find out the cause of the yellowing of Dishui Guanyin leaves in time and prescribe the right medicine.

What are the reasons for the yellowing of Guanyin leaves?

The causes of yellowing or drooping leaves of dripping Guanyin can be divided into the following aspects:

1. The influence of light. Placing dripping Guanyin in living rooms and bedrooms without light for a long time will cause plant photosynthesis due to lack of light, and then affect the life activities of plants. Effects on plant growth and morphogenesis caused by lack of light or lack of light, under this condition, the plant internodes are particularly long, the leaves are underdeveloped and small, and the leaves are yellow due to lack of green leaves.

2. Irrational watering. Dripping Guanyin needs a lot of water, so it is better to be wet than dry in the growing season, and watering should be controlled as far as possible during the winter dormant period. Attention should be paid to the method when watering. Improper watering can easily cause leaves to turn yellow. One wrong way of watering is to pour "half of the water", that is, the water is not watered thoroughly and there is water seepage at the bottom of the Guanyin basin without dripping water. This watering method can not meet the water requirement of dripping Guanyin, and it is easy to cause yellow leaves due to a long-term lack of water at the end of the root system of dripping Guanyin. Another misunderstanding of watering is that watering is irregular, so you can water it once when you think of it, resulting in dripping Guanyin basin soil being too wet or too dry for a long time, which is bad for its growth.

3. The soil condition is not qualified. If the soil used in the cultivation of dripping Guanyin is too alkaline or does not change the soil for a long time, it will lead to the lack of nutrients in the soil, affect the growth of the plant, and then appear the phenomenon of falling leaves, yellow leaves and sagging.

4. Weather reasons. Dishui Guanyin is a tropical plant, which is easy to be cold when the temperature is low in winter. Failure to change the temperature of the growing environment in time will lead to frostbite of the roots and yellowing of leaves. In addition, after the winter, Dishui Guanyin is eager to go out of the room and put it in a warm place to bask in the sun. For a while, it is unable to adapt to the abrupt climate, which will also cause the leaves to turn yellow.

5. Ventilation environment. If you put dripping Guanyin in a poorly ventilated environment for a long time, dripping Guanyin will cause the leaves to turn yellow due to "poor breathing".

6. Cleaning of leaves. Leaves are the main places for plants to conduct photosynthesis. If the leaves are not cleaned by spraying water for a long time, the accumulation of dust will hinder plant photosynthesis, make plant nutrients insufficient, and cause leaves to yellowing.

7. The influence of disease. The main thing that can cause the leaves to yellowing is the red spider, which likes to absorb juice on the back of the leaves. After being killed, the leaves turned yellow and appeared many small white spots, which soon withered and fell off. Often breed in the environment of high temperature and low humidity. Attention should be paid to prevention and control.

8. man-made injury. Artificial damage to the leaves and branches of the plant will lead to damage to the transport system of the plant, so that the nutrition can not reach the leaves, resulting in the yellowing of the leaves.

How to prevent dripping Guanyin leaves from yellowing?

1. Give Dishui Guanyin reasonable lighting conditions. Dishui Guanyin likes a semi-overcast environment. Shade should be paid attention to during maintenance, but remember to keep it in a dark environment for a long time. In addition, we should also pay attention to the ventilation of the environment and keep the air smooth.

2. Dripping Guanyin needs a lot of water. If you want to see it dry, pour it thoroughly at once until there is water flowing out from the bottom of the basin. Watering should be regular and do not make the basin soil too dry or too wet for a long time. When watering, clean the leaves with a spray can to keep them clean, and by the way, you can see the water rolling down from the leaves.

3. Dishui Guanyin does not have high requirements for soil, but it is necessary to ensure the fertility of basin soil, choose sandy loam or humus loam containing organic matter, change soil in time and increase nutrition. In order to increase the resistance of the plant itself, do not simply use nitrogen and phosphorus fertilizer, combined with organic fertilizer alternately, a little ferrous sulfate will make the leaves bigger and greener.

4. Keep the living environment of Dishui Guanyin warm and humid, move it indoors in time when the weather is cold in winter, and slowly change the living environment of Dishui Guanyin to adapt to the change of ambient temperature. remember not to put Dishui Guanyin in an environment where the temperature goes up and down.

5. To prevent man-made damage to dripping Guanyin, the juice of dripping Guanyin is poisonous, so try to avoid physical contact with it. When red spiders appear on the plant, spray with 1000 times of dimethoate emulsion or 1000-1500 times of dichlorvos.
