Hello, everyone, and welcome to watch this issue. I am your good friend Xiaohua. Rhododendron, the protagonist of the term " cuckoo crows blood ", is a traditional beautiful flower that is well-known across the country and has always been well received by people. However, even with it, there are usually many worries. Therefore, today, the editor will elaborate on some of the problems that occur more often when it grows, and I hope it can be helpful to you.
1. Why is this seedling difficult to plant and not easy to survive?
In principle, cuckoo seedlings should not appear on the blacklist of flowers, unless they happen to catch up with the following special circumstances.
1. Excellent soil properties.
As a typical acid-loving flower, rhododendrons are more suitable for cultivation with humus-rich, acidic plant materials, and have a higher survival rate. And to be on the safe side, people should disinfect the soil every time before planting. , Reduce the hidden dangers in safety, disinfestation and sterilization.
2. The slow seedling is not in place.
For azaleas that are in the seedling stage, everyone must keep in mind one thing: a comprehensive and thorough slowing. Choose a suitable time and move the new potted plants to a suitable shade as soon as possible. Avoid direct exposure to the sun or rough application of heavy fertilizer. In addition, people should pay attention to one point after planting, 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 ill.
No matter what kind of phenomenon causes the root system of rhododendron to be damaged,What everyone needs to do at this time generally includes three steps: root repair + disinfection + root drying.
2. Why are the leaves suddenly turning white?
1. Without people knowing, the cuckoo was infected with the terrible powdery mildew , and the main symptom of the disease was the frequent appearance of large and small white spots on the surface of the green leaves of its branches, and The virus is extremely infectious. If it is not stopped as soon as possible, the situation will continue to deteriorate without restraint. In this regard, in addition to buying special medicines for treatment, you can also use some folk remedies that are widely spread-green onion water or rice vinegar water. Usually, after spraying it for about 2 to 3 times, the phenomenon will be greatly improved.
2. The plant's environment is not well ventilated for a long time, and it is often accompanied by unusual high temperature weather. Countermeasures: According to the current situation, scientifically and rationally change the conservation strategy, and strive to adapt measures to local conditions and prescribe the right medicine.
3, Red spider viciously rages. Countermeasure: Use professional insecticides to kill accurately.
3. How to effectively avoid leaf falling caused by improper fertilization?
It is worth noting that although rhododendrons are naturally fertile, they are inherently not tolerant of heavy fertilizers or high-frequency fertilization modes, otherwise their roots will easily be burned to death, causing black rot and rotten roots. Phenomenon. The root system, like the heart, is a special "organ" that focuses on transporting water and nutrients to all parts of the plant body. Once damaged, short-term plants can use emergency plans to reluctantly cope. Over time, the situation will become very unfavorable.This is the root cause of the large leaf fall of the cuckoo. Fortunately, this phenomenon is not completely incurable. Now that we are aware of the seriousness of the problem, we believe that in the future, everyone will be more secure and strictly abide by the principle of "small fertilizer and diligence".
This issue of flower growing knowledge is shared here for the time being. If you want to know more, please send a message or private message to Xiaohua. I would like to be the lampholder on the road of flower growing, accompanied by wind and rain. , Walk along the way.
