How to grow sunflowers in autumn

1. Appropriate amount of water

Because sunflowers originally grow in relatively dry places, they do not require much water, but they still need to be supplemented in an appropriate amount. In autumn, the principle of watering is "alternating dry and wet". Keeping the soil slightly moist can promote its growth.

2. Suitable temperature

In autumn, suitable temperature is very important. Note that the most suitable temperatures are different during the day and at night. The most suitable temperature during the day is between 18 and 30 degrees, and at night it is lower, between 10 and 18 degrees. It is better to control the temperature difference between day and night within eight to ten degrees. Be careful when autumn is almost over, it is best not to drop below ten degrees. If the temperature is too low, take insulation measures.

3. Adequate lighting

It is a short-day plant. Give it enough sunlight when growing it. Every part of it has a strong phototropism. If grown in an environment that is too shady, it will not grow upright, its leaves will droop, and its flower disk will be very small.

4. Appropriate amount of fertilizer

It is in its growth stage in the fall and needs to be fertilized. Usually once a week to ten days. Mainly use nitrogen fertilizer.

5. Dealing with pests and diseases

Pests and diseases can threaten the growth and flowering of sunflowers. Therefore, when raising it, you should use pesticides and insecticides in moderation to deal with diseases and pests.
