What s the deal with rhododendron yellow leaves? What can be done to improve!

1. Soil is too alkaline.

1. Reason: Rhododendron is a flower that prefers weakly acidic soil. If it is usually raised in soil that is too alkaline, it will not be able to adapt, it will not be able to grow normally, and yellow leaves will appear.

2. Treatment method: If it is convenient, it is recommended to change the soil for the plant and use the slightly acidic new soil as its new cultivation soil. It's good for it to grow. If it is not convenient to change the soil, you can also acidify its culture soil by watering ferrous sulfate solution every month.

Second, the light is too strong.

1. Reason: It likes plenty of sunlight without too much intensity. If the environment where it is raised is very bright, its leaves will be sunburned, which may cause it to appear yellow leaves.

2. Treatment method: change the plant to a shaded place, properly ventilate, and cut off the leaves that have turned yellow. After a while, it is able to grow new leaves.

3. Overwatering.

1. Reason: Although it is suitable for growing in slightly moist soil, it is not very resistant to waterlogging. If it is overwatered when raising it, it will cause too much water to accumulate in the flower soil, which may damage its root system and make it appear yellow leaves.

2. Treatment method: At this time, take it out of the original pot and cut off the rotten roots. Then put it in a well-ventilated place to dry, and then plant it in the new soil to cure.

1. Adjust watering.

Reason: The yellow leaves of azaleas are most likely caused by drought and lack of water, and if the potted plant is left unmanaged for a long time and placed in a place where it does not rain, it will slowly dry up due to lack of water. Or if you water too much and rain for too long, the leaves will turn yellow because the roots can't breathe.

Solution: If the yellow leaves are caused by drought and lack of water, just water it in time, and at the same time, temporarily put it in a shaded position to let it slow down, and it will recover soon. If it is because of stagnant water, and ensure that the indoor temperature is between 5-10 can survive the winter smoothly, and at the same time, it is also caused by poor water permeability, you need to drain it in time, if the condition of yellow leaves is more serious, you also need to depot to check its root system.

Cuckoo. 2. Adjust the lighting.

Reason: Rhododendron likes to grow in a sunny environment, if the maintenance environment is too closed, it will cause it to not fully photosynthesize, resulting in yellowing of leaves. In addition, in the hot summer, it should not be exposed to the sun for a long time, and it is easy to sunburn the leaves, which will also cause the leaves to turn yellow.

Solution: If it is caused by a lack of light, it is necessary to gradually improve the lighting conditions of the maintenance environment to ensure that there is a longer period of light every day, but it can not be exposed to the sun in summer, and it can be shaded with a shade net or black gauze.

Cuckoo. 3. Keep warm.

Reason: Rhododendron is not very cold-tolerant, if the ambient temperature is lower than 5, it will stop growing, and the leaves will gradually turn yellow and fall off.

Solution: Before the winter cooling, it is necessary to do a good job of heat preservation, and move it to a warm place in advance to maintain it in a place with good lighting conditions. Cuckoo.

<> rhododendron yellow leaves, may be caused by alkaline soil, dry environment, infection and disease, when breeding rhododendrons, it is necessary to water ferrous sulfate once a month to make the soil more acidic, and regularly spray water mist on the azalea to improve the humidity of the air, and spray the bactericide every other week to restore the azalea leaves.

1. The soil is alkaline.

Rhododendron is suitable for growing in acidic soil, when breeding rhododendrons, if the soil is alkaline, it will lead to poor growth of rhododendrons, hunger and panicle so that its leaves turn yellow, it is necessary to apply ferrous sulfate every other month to adjust the pH of the soil, make the soil acidic, and maintain the normal growth of rhododendrons.

2. The environment is dry.

When cultivating rhododendrons, if the environment is too dry, it will lead to a lack of water in the plants, which will make the leaves of the azaleas yellow and dry, and it is necessary to spray water mist on the leaves of the azalea every day to improve the humidity of the air, and to water every other week to restore the leaves of the azalea to green and green.

3. Infection with diseases.

The yellowing of the leaves of the azalea may be caused by the infection of the plant with leaf blight, at this time, it is necessary to cut off all the yellowing leaves of the azalea to avoid the loss of excess nutrients, and spray the bactericide every other week to make the azalea grow healthily.

4. Maintenance method.

When maintaining rhododendrons, it is necessary to change the potting soil every 2 years, which can provide it with rich organic matter content and good air permeability.

Rhododendron yellow leaves, may be the soil alkaline, dry environment, infection caused by diseases, breeding rhododendrons, need to water ferrous sulfate once a month, so that the soil is acidic, and regularly spray water mist to the azaleas, improve the humidity of the air, and to spray a bactericide every other week, so that the azalea leaves restore emerald green.
