Why do the leaves of the dripping Guanyin turn yellow?

reason

1. Lighting influence

Placing the weeping angel in a living room, bedroom or other place with a lack of light for a long time will cause the plant's photosynthesis due to insufficient light, thus affecting the plant's life activities. The effect of insufficient or no light on plant growth and morphological formation. Under such conditions, the internodes of the plant are particularly long, the leaves are underdeveloped and small, lacking leaf green and appearing yellow.

2. Improper watering

The weeping angel has a large water requirement. During the growing season, it is better to keep it wet than dry. During the winter dormancy period, watering should be controlled as much as possible. Pay attention to the method when watering. Improper watering can easily cause the leaves to turn yellow. A wrong way of watering is to water "half way", that is, watering is not thorough, and water seepage occurs at the bottom of the dripping Guanyin pot. This watering method cannot meet the water needs of the weeping angel, which can easily cause long-term water shortage at the root end of the weeping angel and cause yellow leaves. Another misunderstanding in watering is watering irregularly, watering only when you remember to, causing the soil in the weeping angel pot to be too wet or too dry for a long time, which is not conducive to its growth.

3. Unqualified soil

If the soil used to grow the weeping angel is too alkaline or the soil is not changed for a long time, it will lead to a lack of nutrients in the soil, affecting the growth of the plant, and causing the plant's leaves to fall over, turn yellow, and droop.

4. Weather reasons

The weeping angel is a tropical plant. It is easily affected by cold in the winter when the temperature is low. Failure to change the temperature of the growing environment in time will cause frostbite on the roots and cause the leaves to turn yellow. In addition, after winter, the weeping angel is eager to go out of the house and be placed in a warm place to bask in the sun. It cannot adapt to the sudden change in climate for a while, which can also cause the leaves to turn yellow.

5. Ventilation environment

If the Weeping Guanyin is placed in a poorly ventilated environment for a long time, the leaves of the Weeping Guanyin will turn yellow due to "poor breathing".

6. Leaf cleaning

Leaves are the main site for photosynthesis in plants. If the leaves are not sprayed with water to clean them for a long time, dust will accumulate and it will hinder the photosynthesis of the plants, causing the plants to lack nutrients and causing the leaves to turn yellow.

7. Impact of diseases

The main cause of yellowing leaves is red spider mites, which like to suck sap from the back of leaves. The damaged leaves turn yellow and have many small white spots, and soon they turn yellow and fall off. It often breeds in high temperature and low humidity environments. Pay attention to prevention and treatment.

8. Man-made damage

Artificial damage to the leaves and branches of the plant will damage the plant's transport system, resulting in nutrients not reaching the leaves, causing the leaves to turn yellow.

How to Prevent Yellowing Leaves

To prevent the leaves of the weeping angel from turning yellow, you must start with the cause and prescribe the right remedy.

1. Reasonable lighting and ventilation

Provide the Weeping Guanyin with reasonable lighting conditions. The Weeping Guanyin prefers a semi-shaded environment. Pay attention to shade when caring for it, but remember not to place it in a dark environment for a long time. In addition, pay attention to the ventilation of the environment and keep the air flowing.

2. Watering requirements

The weeping angel needs a lot of water. Water it when the soil is dry and water it thoroughly at one time until water flows out from the bottom of the pot. Water regularly and do not let the soil in the pot be too dry or too wet for a long time. When watering, use a spray bottle to clean the leaves to keep them clean. You can also see the water rolling down the leaves.

3. Soil requirements

The weeping angel plant does not have high requirements for soil, but the fertility of the potting soil medium must be ensured. Choose sandy loam or humus loam containing organic matter, change the soil in time, and increase nutrition. To increase the plant's own resistance, do not use only nitrogen and phosphorus fertilizers, but use them alternately in combination with organic fertilizers. Applying a little ferrous sulfate will make the leaves larger and greener.

4. Maintain a suitable temperature

Keep the living environment of the Weeping Guanyin warm and humid, and move it indoors in time when the weather is cold in winter; slowly change the living environment of the Weeping Guanyin to allow it to adapt to changes in ambient temperature. Remember not to place the Weeping Guanyin in an environment where the temperature fluctuates.

5. Avoid human-caused damage

Prevent human damage to the weeping angel. The juice of the weeping angel is poisonous, so try to avoid contact with its body. When red spider mites appear on the plants, spray with 1000 times diluted 40% dimethoate emulsion or 1000-1500 times diluted 80% dichlorvos.
