1、 Temperature

According to the characteristics of sunflower, the most suitable temperature condition is 25 to 35 degrees. You can pay no attention in early autumn. However, when the temperature is low in late autumn, it should be regulated. Even if it cannot be guaranteed to be too high, it should not be lower than 10 degrees, otherwise it may affect the normal growth process

2、 Illumination

Just entering autumn, the light is still relatively strong, so we should pay attention to shading. Under the strong light, its leaves will turn brown. Generally speaking, the maintenance can meet the requirements if it is placed in a place with bright indoor light

3、 Air humidity

Raise loose tail sunflower. The humidity of the surrounding environment should be higher. It's best to control it at 70-80%. If the air is dry, spray some water appropriately. Too low humidity will cause the leaf tips to become dry

4、 Watering

Watering can be regulated according to the state of the surface soil, and water can be added after it is dry. If it's cloudy, you'd better not water it first. At the end of autumn, we should slowly reduce the amount of water

5、 Fertilizer

In autumn, it has little demand for fertilizer. If the growth is not good, you can apply fertilizer, then the amount should not be too much

6、 Trim properly

Before entering winter, a pruning should be carried out to help the sunflower spend the winter. Cut off the sick, insect, weak and dead branches, and cut off part of the too dense and messy branches
