How to grow beautiful southern flowers in the north

In China, due to regional differences, it is often difficult to raise flowers in the south in the north. In fact, as long as we know more about the habits of southern flowers and create a suitable environment for flowers according to the climatic environment of southern cities, southern flowers can also thrive in the north.

1. Increase the humidity of the air. As the air humidity in the north is small, most flowers in the south can not adapt to the dry air, so it is very important to increase the air humidity. According to the measurement of relevant departments, in addition to reasonable watering, it is also necessary to increase water spraying measures in the process of cultivation in Beijing area. During the early rainy season and hot summer flower cultivation, we should often sprinkle water on the leaf surface and the ground to increase air humidity, this measure can effectively prevent the occurrence of tender leaf dry tip or leaf edge scorching and other phenomena. For a small number of precious flowers in winter, we should also put on a plastic film cover, which can not only keep warm and moisturizing, but also prevent dust and keep the plants clean and fresh.

2. Improve the acidity and alkalinity of soil and water. The soil is alkaline in the north and sour in the south, and the loose, fertile and slightly acidic culture soil suitable for flower growth in the south is carefully prepared, and the soft water with less salt is selected. at the same time, alum fertilizer water is often used to make the basin soil acidic during the flower growth period. this is an important link in raising flowers in the south.

3. Pay attention to proper shading in summer. The sunshine intensity is high in summer in most parts of the north, so if the southern flowers are maintained in the bright light, it is easy to cause sunburn. Therefore, after the beginning of summer, according to the degree of light preference of flowers, we should give different shade or change the position of flowerpots to avoid strong light in order to make them grow healthily. In summer, reeds or bamboo curtains can be used to set up a shade shed with a light transmittance of 30% to 50%, which can improve the light intensity and facilitate the growth of flowers in the south.

4. Pay attention to heat preservation and cold prevention in winter. In most areas of the north, potted flowers need to be moved to the greenhouse for conservation in the first and middle of October. After the room, according to the different requirements of different kinds of flowers for light and temperature, they are placed in different positions. In general, the lowest temperature of flowers in winter should be kept above 10 ℃.
