1、 How can it flourish

1. Soil: sunflower is not suitable for growing in alkaline soil. In order to make it grow vigorously, it needs to provide soil suitable for growth. The soil is required to be loose, fertile, good drainage and slightly acidic. The soil can be prepared with peat soil, river sand and base fertilizer. It needs to be raised for two or three years to change the basin soil

2. Light: it prefers a semi cloudy environment. There is a demand for light, but it is better to contact astigmatism. It can't be kept in a place without sunshine for a long time. Pay special attention in summer. Exposure to strong light will cause leaves to burn and turn yellow, so pay attention to shielding

3. Temperature: the sunflower grows well in a warm environment, and it is suitable to keep it at about 15-28 degrees. In winter, we should pay attention to keeping warm and cold proof, and the temperature should be raised to more than 10 degrees

4. Watering: it needs to keep the basin soil moist during the vigorous growth period. Pay special attention to replenishing water in time in summer and reduce watering in winter

5. Fertilization: lush growth is inseparable from the application of nutrients. In the period of rapid and vigorous growth, fertilizer can be applied every half a month or a month, and thin liquid fertilizer can be used. Be careful not to apply fertilizer on the leaves, otherwise it will cause decay

6. Humidity: maintain high air humidity around the plant, which is conducive to vigorous growth. Spray water on the leaf surface and around to improve air humidity
