How to preserve Osmanthus fragrans in buildings

For urban residents living in buildings, it is very difficult to cultivate sweet-scented osmanthus, mainly because the growth environment and conditions have changed greatly after sweet-scented osmanthus was transplanted from the original place to the city. Therefore, necessary measures should be taken in the cultivation and management of sweet-scented osmanthus to create a suitable microclimate for the normal growth and development of hanging flowers. Generally speaking: prevent high temperature in winter and dry in summer. The temperature required for normal dormancy of sweet-scented osmanthus is between 0 ℃ and 5 ℃. The bud of sweet-scented osmanthus may be damaged by freezing below 0 ℃. The buds of sweet-scented osmanthus germinate and germinate when the temperature is higher than 5 ℃. Nowadays, urban buildings are generally heated by central heating, and the room temperature is mostly above 15 ℃. Under such temperature conditions, sweet-scented osmanthus will break the normal dormancy period, early branch and leaf expansion, not only can not accumulate sufficient nutrition through normal dormancy, but also prematurely consume a lot of nutrients in the body, resulting in false lush and prosperity. After the sweet-scented osmanthus leaves the room in spring, the delicate branches and leaves can not stand the beating of the cold and dry wind, and will soon wilt and wither. If continuous for 2 to 3 years, the whole sweet-scented osmanthus plant will die. For those who live on the first floor and have a courtyard, it is best not to put sweet-scented osmanthus on the balcony or in the room in winter. Because the room temperature is too high, not conducive to the dormancy of sweet-scented osmanthus, although the balcony temperature is lower, but its height is not easy to control, the temperature is suddenly high and low, which is disadvantageous to the dormancy of sweet-scented osmanthus. You can dig a pit in the sunny corner of the courtyard, depending on the size of the flowerpot, put the flowerpot in, fill it with the flowerpot, bury the flowerpot with soil, build a frame, and cover it with plastic film. Those who live on the second floor and above should put sweet-scented osmanthus on the balcony in winter and create a suitable environment for sweet-scented osmanthus. The specific method is: seal the balcony with aluminum alloy glass windows to avoid cold air intrusion, at the same time, use glass windows and doors to separate the balcony from the interior to prevent heating from entering, rely on the natural temperature of the balcony, you can meet the requirements of sweet-scented osmanthus dormancy. If in the cold northeast region, when the balcony temperature is below 0 ℃, you can slightly open the doors and windows and put in a small amount of heating to keep the balcony temperature between 0 ℃ and 5 ℃. Osmanthus fragrans can survive the winter safely. In spring, with the gradual rise of the temperature, we should gradually open the window of the balcony so that the temperature inside the balcony slowly adapts to the temperature outside. When the average temperature reaches above 0 ℃, all the windows of the balcony can be opened. Be careful not to open the window too hastily, lest sweet-scented osmanthus get hurt. In summer, preventing drying is an important part of sweet-scented osmanthus management. The balcony air is hot and dry and the ventilation is not smooth, which is very disadvantageous to the growth and development of sweet-scented osmanthus. Sweet-scented osmanthus is native to the humid and well-ventilated natural environment in China, so it is necessary to create a suitable environment for it and open the doors and windows of the balcony as far as possible to maintain ventilation. At the same time, to increase the humidity of the air, you can spread a layer of brick or cushions such as a mat that can absorb water on the floor of the balcony, put sweet-scented osmanthus on it, and often splash water on the bedding to make it fully absorb water. Rely on the natural evaporation of water to create a humid environment for sweet-scented osmanthus. In addition, in the hot summer, spraying water on the branches and leaves of sweet-scented osmanthus at any time can not only reduce the temperature of sweet-scented osmanthus plants, wash the dust on the leaves of sweet-scented osmanthus, but also meet the moisture requirements of sweet-scented osmanthus.
