The blackening and scorching of the leaves of Azalea (Yingshan Red) are caused by these reasons!

The rhododendron we are familiar with, also known as Yingshanhong, is one of the top ten traditional flowers in China. Its color is bright red and very beautiful. It is said that azaleas are stained with blood from birds. In spring, when we travel through the mountains, we often see patches of azaleas swinging in the wind, like fairies in red clothes. Now, many people plant it in their own courtyard or indoors. In the specific maintenance process, the leaves of azaleas often turn black and scorched, so what is the cause of this situation? What should we do about it?

First, the reasons for the blackening and scorching of rhododendron leaves

1. Overwatering

This is the most common mistake made by many novice flower growers. Newly planted flowers do not care about anything, do not understand their habits, water them every day, no matter whether they live or die, it will not take long to find out that something is wrong with them more and more. Therefore, when raising azaleas, it is also very easy to water them desperately, but they do not realize that azaleas are very afraid of accumulating water. if they encounter high temperature weather after too much watering, they will rot their roots and cause the leaves to blacken and scorch, thus falling off.

2. Long-term drought

It is fine in winter, and it will not have much effect if the azaleas are not watered for a long time. If it is a hot summer, if you leave it unwatered for ten and a half days, you will find that its leaves are black and scorched, because at this time the temperature is high and the water evaporates quickly.

3. Sunburn

Although rhododendron is a kind of flower that likes light, it can't stand the sunshine in the hot summer. If it is still placed on the balcony for a long time in the hot summer, the leaves will burn, blacken and scorch.

4. Poor ventilation

Ventilation is also one of the reasons why the leaves are scorched, because if the rhododendron is not cooled in time and placed in a ventilated place when the temperature is high, it is easy to get hurt from the muggy heat.

5. Excessive fertilization

Although azaleas are fertilizer-loving flowers, many people will ignore one point. In hot weather, fertilizers are fertilized as usual, resulting in excessive concentration of fertilizer, resulting in blackening and scorching of leaves, and in serious cases, the whole rhododendron will die.

6. caused by diseases and insect pests

Azaleas may also be attacked by diseases and insect pests if their leaves are black and charred, such as the most common brown spot, which is initially a small spot, and when it spreads, the whole leaf will scorch off.

Second, the solution to the blackening and scorching of rhododendron leaves

1. The phenomenon of blackening and scorching caused by too much watering must be the root system rotten, so it is necessary to change the basin quickly, gently shake off the soil of the root system, cut off the blackened root system with scissors, and plant it in a new pot after dealing with the wound. put it in a cool and ventilated place for a period of time to recover.

2. If the leaves are blackened and charred by long-term drought, the dry and blackened leaves should be cut off first, so as not to occupy the nutrients of the whole plant, and then watered. Do not water too much at once, slowly, and wait until the plant returns to normal growth before it can be watered as before.

3. Sunburn causes the leaves to blacken and zoom as long as we pay more attention in the maintenance process and give shade and moisture timely in summer, it can also grow well.

4. If the leaves are blackened and charred due to poor ventilation, the blackened and charred leaves of the azaleas are first reduced, and then moved to the ventilated environment, spraying water to the leaves and plants at the right time, cooling and humidifying.

5. The blackening and coking of leaves caused by excessive fertilization must remember the four-word principle of fertilization and should be treated on a case-by-case basis.

6. if the leaves are blackened and charred by diseases and insect pests, the diseased leaves should be removed in time to avoid infecting the whole plant, and diseases and insect pests can be treated in time, and some pesticides can be sprayed to get rid of the diseases and insect pests.

To sum up: if you raise rhododendrons in a similar situation quickly "symptomatic solution", usually as long as careful care, I believe you will be able to grow beautiful rhododendron pots.
