The greatest value of sweet-scented osmanthus trees is flowers. The appreciation value of flowers is very high, and the utilization value is also very high. People like sweet-scented osmanthus trees because the aroma of sweet-scented osmanthus is overwhelming. "fragrance in ten miles" is the description of sweet-scented osmanthus. But how unpleasant it is if the sweet-scented osmanthus does not blossom. It is also a very confusing thing. But it happens all the time. Why don't sweet-scented osmanthus trees bloom? The editor will answer for you.

Why don't sweet-scented osmanthus trees blossom? First, lack of light has a great impact on the flowering of sweet-scented osmanthus trees. Sweet-scented osmanthus has a high demand for light. If there is not enough light, it is difficult to form flower buds. Only when planted in a sunny and well-ventilated place, can it blossom normally. Therefore, if long-term shade, can not accept the sunlight will affect the formation of flower buds. In this way, even if there are flower buds, they will fall. Sweet-scented osmanthus trees do not blossom is common in the community, because there are many tall buildings and lack of sunshine. Second, air pollution will also affect the flowering of sweet-scented osmanthus trees. If the air pollution is too serious, it will not blossom, and the leaves may fall. For example, the longer the leaves are, the smaller they are, and they are easy to fall off. Especially the blooming effect of sweet-scented osmanthus trees in the center of the city is not good. Third, serious stagnant water is very harmful to the roots of sweet-scented osmanthus trees, too much water will cause root rot. Sweet-scented osmanthus trees like high dry, well-drained sandy loam, if the soil water, a long time will cause rotten roots, roots are rotten of course will not blossom. Therefore, when planting sweet-scented osmanthus trees, we should pay attention to the choice of its growth environment. Fourth, the harm of diseases and insect pests, although sweet-scented osmanthus diseases and insect pests are relatively few, but as long as it is in a shady, humid and ventilated environment, it will cause disease, resulting in withered and yellow leaves, fewer flowers and smaller flowers. At this time, insecticides should be used to kill scale insects and aphids. Specifically, 1000 times of thiophanate methyl can be sprayed to treat diseases. Fifth, insufficient fertilizer will also affect the flowering of sweet-scented osmanthus trees. How can it blossom and bear fruit if it is not nutritious enough? Lack of fertilizer will lead to poor growth and development, and some sweet-scented osmanthus planting environment is not good, which naturally results in insufficient nutrition, weak growth of trees and withered leaves. Therefore, proper fertilization should be applied. However, we can not apply fertilizer blindly, and we can no longer change the time of fertilization, which will also affect the formation of flower buds, and it is also the reason for not blooming and less flowering. Conclusion: the reason why sweet-scented osmanthus trees do not blossom may be the above reasons or the co-existence of several reasons. Therefore, there is a reason why sweet-scented osmanthus trees do not blossom. It is not the problem of tree species, but the problem of breeding. Sweet-scented osmanthus is a kind of excellent garden tree species which integrates greening, beautification and fragrance, and it is also a common green plant to beautify the city on both sides of the street.

Why don't sweet-scented osmanthus trees bloom?

Sweet-scented osmanthus trees can tolerate shade and are bright green in color, so they are suitable for growing when the sun is not enough. Sweet-scented osmanthus trees take a long time to grow, but they may not blossom. So why don't sweet-scented osmanthus trees blossom? Let's find out why sweet-scented osmanthus trees don't blossom.

Why don't sweet-scented osmanthus trees bloom?

The reasons why sweet-scented osmanthus trees do not blossom are as follows:

Smoke and dust pollution in recent years, some reports think that the leaves of sweet-scented osmanthus trees have strong resistance to sulfur dioxide, hydrogen fluoride, chlorine and other polluting gases, so sweet-scented osmanthus trees are planted in many urban parks. But in fact, because the sweet-scented osmanthus tree is native to the mountain area of the environmental scene, its growth conditions require clean air. In the air containing smoke and dust, although it may not necessarily cause damage to the leaves, it is enough to inhibit its normal flowering. Sweet-scented osmanthus tree is a kind of tree species that is not polluted by smoke and dust, so it is not suitable to be planted in places with dense factories.

In addition, on the side of the road with a large number of vehicles, it often affects the blooming of sweet-scented osmanthus trees because of the serious traffic dust.

Soil conditions are not suitable for the growth of sweet-scented osmanthus trees. Sweet-scented osmanthus trees are native to the acidic soil areas in southern China, such as Suzhou, Hangzhou, Guilin and so on. The soil is acidic or weakly acidic, and the pH value is about 5.6 ~ 6.8. However, the soil in some gardens in the city is alkaline due to the long-term influence of industrial dust, construction waste and human feces and urine. Therefore, sweet-scented osmanthus trees do not grow well in areas with high salinity in alkaline soil (such as coastal areas), and those who can blossom are even less.

Sweet-scented osmanthus trees are native to mountainous areas, which require soft soil and good drainage, but many cities have flat terrain and poor drainage, and some have a high groundwater level (such as only 0.5 meters in Shanghai), resulting in poor root development of sweet-scented osmanthus trees. Good drainage is an important condition for the growth of Osmanthus fragrans.

During improper maintenance and management, the root system and soil blocks carried by transplant are not well protected, or the aboveground branches and leaves are lack of proper pruning, resulting in the imbalance of physiological balance between underground roots and aboveground branches and leaves, as well as improper maintenance and management after planting.

Osmanthus fragrans is a slow-growing positive tree species. When mixed with other tree species, it is easy to be shaded by nearby fast-growing trees. According to the regulation, the crown of sweet-scented osmanthus can hardly blossom normally, especially when it is covered by other tree species to the south. Only in places where there is plenty of light can the pronunciation grow mysteriously. However, sweet-scented osmanthus trees can not stand long-term hot sun exposure and drought. we have seen more than once that during high temperatures in summer, especially in gardens with more cement floors, sweet-scented osmanthus trees often have abnormal mother leaves, causing the trees to retreat and cannot blossom. Although sweet-scented osmanthus trees are distributed in tropical areas, such as Hainan Island, Taiwan and Lingnan, their growth and mother are far less than those in subtropical areas, indicating that sweet-scented osmanthus trees have relatively strict requirements on climatic conditions.

Because some chewable mouthparts pests such as stinging ammonium and pocket moth do not like to eat the leaves of sweet-scented osmanthus trees, and they are easy to control, some people mistakenly think that they do not need to pay special attention to the diseases and insect pests of sweet-scented osmanthus trees, but this is not the case. It is true that the death of the whole sweet-scented osmanthus tree due to diseases and insect pests is very rare, but there are several diseases and insect pests that can endanger the flowering of sweet-scented osmanthus trees. Small and unnoticed pests such as red spiders, whiteflies, shell insects and military insects often make sweet-scented osmanthus trees yellowing and weakening their growth, especially in poorly ventilated, shaded and humid places. In addition, in the location of local water retention, the root system of sweet-scented osmanthus tree is easy to be damaged by some facultative parasites such as Fusarium oxysporum, resulting in root rot. These diseases and insects can inhibit the flowering of sweet-scented osmanthus trees, but they are often ignored by people.

Why don't sweet-scented osmanthus trees bloom? how to plant sweet-scented osmanthus trees?

Sweet-scented osmanthus tree is a kind of tree species which integrates greening, beautification and fragrance, and has a strong ornamental value. Osmanthus fragrance is charming, and many people like to plant sweet-scented osmanthus in their homes. But sweet-scented osmanthus sometimes does not blossom, so why do not sweet-scented osmanthus trees blossom, how to plant sweet-scented osmanthus trees, let's learn!

Why don't sweet-scented osmanthus trees bloom?

1. Improper selection of seedlings

Why don't sweet-scented osmanthus trees bloom? It may be improper seedling selection, because there is a kind of sweet-scented osmanthus called purple cinnamon, which can not blossom until it grows up, but it is difficult to blossom if this purple cinnamon is cut into a real seedling. If you want sweet-scented osmanthus to grow well and bloom a lot of flowers, you must choose seedlings with good varieties, which is very important. Only choosing good seedlings of sweet-scented osmanthus will be more convenient in the process of cultivation.

Second, improper cultivation

The vitality of sweet-scented osmanthus is relatively strong, if sweet-scented osmanthus does not bloom, it may also be the reason for improper planting. Sweet-scented osmanthus trees are most suitable for planting in sandy soil, where they rarely bloom in more alkaline soil, and their growth will be affected if they are rooted or frozen during transplanting. Sweet-scented osmanthus trees prefer light and avoid temperature, and their flowering will be affected if they are exposed to insufficient light for a long time.

III. Imbalance in fertilizer proportion

Sweet-scented osmanthus tree is a kind of fertilizer-loving plant, but too much fertilizer is also harmful to it, so we must pay attention to the balance of fertilizer when applying fertilizer. If there is more nitrogen fertilizer, it will flourish, branches and leaves will grow, resulting in no flowering, but less leaves and yellow branches will be thin, affecting the absorption of phosphorus and potash fertilizer, and will not bloom.

4. Caused by diseases

Finally, the non-flowering of sweet-scented osmanthus is likely to be caused by diseases. Sweet-scented osmanthus trees are vulnerable to a variety of diseases, such as anthrax, shell insects and so on.
