Hello, everyone, welcome to watch this issue, I am your good friend Xiaohua. The cuckoo, the protagonist of the term "cuckoo crying blood", is a traditional beautiful flower that is well-known in China, and has always been well received by everyone. However, even if it is, there are many troubles in normal times. Therefore, today's words, Xiaobian will talk in detail about some of the problems that often occur when it grows, and I hope to be able to help you.
First, why is it difficult to plant and survive the seedlings?
In principle, rhododendron seedlings should not have appeared on the blacklist of flowers, unless by chance, they coincided with the following special circumstances.
1. Excellent soil properties.
As a typical acid-loving flower, rhododendron is more suitable for the use of humus-rich, acidic growing medium cultivation, the probability of survival is higher, and for the sake of insurance, before each planting, people should disinfect the soil well, reduce safety risks, insecticide and sterilization.
2. Slow seedlings are not in place.
For rhododendrons that are in the seedling stage, it is important to keep one thing in mind: comprehensive and thorough seedlings. Choose a suitable time to move the new potted plants to the right shade as soon as possible, and avoid direct exposure to the sun or rough application of thick fertilizer. In addition, after planting, people should also pay attention to the fact that it is best not to press the soil too hard, so as not to accidentally aggravate the soil compaction and affect its normal growth and development process.
3. The root system of the plant is sick.
No matter what the phenomenon causes the root system of rhododendron to be damaged, what everyone has to do at this time generally includes three steps: root repair + disinfection and sterilization + drying.
Second, why do the leaves suddenly turn white in large quantities?
1, when people are unaware, rhododendron unfortunately infected with terrible powdery mildew, and the main symptom of the disease, is the surface of its branches and green leaves, frequent appearance of large and small white spots, and a transmission of ten, ten hundred, the virus is extremely infectious, if not stopped as soon as possible, the situation will continue to deteriorate uncontrollably. In this regard, in addition to purchasing special drugs for treatment, we can also use some folk remedies that are widely spread - green onion water or rice vinegar water, usually after about 2 to 3 sprays, the phenomenon will be greatly improved.
2. The ventilation of the environment in which the plant is located is poor for a long time, and it is often accompanied by abnormal high temperature weather. Countermeasures: According to the current situation, scientifically and rationally change the conservation strategy, and strive to adapt to local conditions and prescribe the right medicine.
3. The viciousness of the red spider is rampant. Countermeasures: Accurate hunting with professional insecticides.
Third, due to improper fertilization caused by the phenomenon of leaf fall, how to effectively avoid?
It is worth noting that although the cuckoo is born to like fertilizer, it is essentially not tolerant of thick fertilizer or high-frequency fertilization mode, otherwise its root system will easily be burned to death, causing corresponding phenomena such as black rot and rotten roots. The root system, like the heart, focuses on delivering water and nutrients to various parts of the plant body, and once damaged, the short-term plant can also use emergency plans to cope with it, and over time, the situation will become very unfavorable, which is the root cause of the large leaf fall of the rhododendron. Fortunately, this phenomenon is not completely irredeemable, since we are aware of the seriousness of the problem, I believe that in the future, in the matter of fertilization, everyone will certainly be more prudent and strictly abide by the implementation of the principle of "thin fertilizer and diligent application".
