Do sunflower seeds need sunlight to germinate?

1. Do you need sunlight?

Sunflowers love sunlight very much. Sunlight is a very critical factor. Germination requires a certain amount of sunlight. You can bury the seeds in the soil, then water them thoroughly and place them in a sunny place. In a warm growing environment, they will sprout and grow in about 5-7 days. After the small buds grow, they still need sunlight and must be exposed to light at all times. This will encourage the small buds to grow taller and taller, and the leaves will gradually grow larger. However, the time exposed to sunlight cannot be too long, as long-term strong light can also be irritating. If there is no sunlight for a long time, the sunflower will have growth problems and the seedlings will not be able to grow strong.

2. The role of sunlight

1. Before germination: Before germination, place it in a sunny place to increase the overall temperature and promote germination and growth as soon as possible.

2. Seedling stage: After the seedlings germinate and grow, appropriate amount of sunlight can make the seedlings strong, prevent them from growing too tall, and promote their growth as quickly as possible.

3. Mid-growth period: Sufficient sunlight at this time can promote vigorous growth of stems and leaves, and ensure normal flowering and pollination.

4. Late reproductive stage: In the late reproductive stage, it is the period of growing grains. Maintaining sufficient sunlight at this time can promote the development of full and plump grains.
