What to do with the rhododendron after it is waterlogged?

Many flower friends say that rhododendrons are more difficult to raise, and there are often yellow leaves and fallen leaves in the maintenance process, and if effective measures are not taken in time, it will lead to the wilting of the whole plant. The causes of the yellow leaves of the rhododendron are also different, but most of them are related to the pH imbalance, the rhododendron is a very acidic flower, when the soil is not acidic enough, its leaves will gradually begin to appear yellow, until they fall off. It's best to give it some acidic fertilizer often.

1. Alkaline yellow leaves of potting soil

Flowers such as rhododendrons, gardenias, and jasmine are typical flowers that like acidity, and if the acidity in the soil does not meet the requirements, it is easy to have yellow leaves. That is, what we call iron deficiency yellow leaves, this yellow leaf is characterized by yellowing of the leaves, but the veins of the leaves are still green, and it should be supplemented with nutrients in time.

For the treatment of iron deficiency yellow leaves, the most effective way is to directly supplement ferrous sulfate solution, every time you water it, add a small amount of ferrous sulfate, generally use 2 3 times can have a very good effect.

In order to prevent acid-loving flowers from alkaline yellow leaves, you can also apply more well-rotted organic fertilizer to it, or add a few drops of salt-free white vinegar when watering, which can improve the acidity of the soil.

2. Yellow leaves caused by waterlogging

The root system of the rhododendron is relatively slender, the water absorption ability is not strong, when it is watered too much and there is water accumulation, it is easy to cause suffocation of the root system, thereby causing damage to the absorption tissue, resulting in the phenomenon of yellow leaves.

Rhododendron watering is generally not easy to grasp reasonably, because it is not only afraid of waterlogging, but also a flower that prefers a humid environment. In the dry season, water should be sprinkled frequently around the plant to increase the humidity of the environment.

When a large number of yellow leaves are caused by too much watering, watering should be stopped immediately, and the potted plants should be moved to a cool and ventilated place for maintenance, and the soil should be loosened frequently to increase the air permeability of the soil. For more serious cases, prune branches and leaves in time, and remove potting and replace potting soil.

Third, too strong light is easy to cause yellow leaves

Rhododendron is very afraid of strong direct sunlight, with the increase of temperature, the light intensity also begins to increase, at this time to do a good job of shading and sun protection measures, otherwise it is easy to dry the leaves of the rhododendron, causing the leaves to dry and scorch.

Especially in summer, it is necessary to keep the rhododendron in a cool and ventilated environment, and when it is hot and dry, it is best to sprinkle water on the plants several times a day to cool down and humidify.

In addition, it is necessary to ensure that the environment is well ventilated, and in a hot and humid environment, it is easier to breed various pests and diseases, and it is also necessary to do a good job of prevention in advance.

Conclusion: Now the temperature is gradually rising, the light intensity is also increasing, at this time the rhododendron is prone to different reasons of yellow leaves, should be timely strengthen the maintenance management, to ensure that the fertilizer and water are sufficient, and often sprinkle water to the plant to increase the humidity of the environment, in order to facilitate the healthy growth of the plant.

Water less and loosen the soil. Quickly put in a ventilated place, the temperature must be warm. Use chopsticks to exhaust and drain the soil around the pot through a few holes, and put it in shelter on rainy days to prevent the airtightness of the rhododendron's roots and rotten roots.

Moist soil should be dug out in time and placed in a ventilated place to evaporate excess water. The roots of the azalea are then dried and replanted.

I don't think it's watering it just yet, and put it in a well-ventilated and sunny place. Raising flowers requires a lot of patience.

It's not about vinegar, it's about fat. It is necessary to fill more water to promote the fertilizer to seep out of the bottom hole, and the fertilizer concentration will slowly return to normal after 5-7 days after thinning.

If you don't have it, the root system is destroyed, try 3 hours of foliar spray.
