How to plant sunflower seeds

After the seeds are soaked, they can be sown. The method is very simple. Sprinkle the sunflower seeds evenly on the soil surface, and then cover them with a layer of fine soil. After sowing the seeds, place them in a natural environment with sufficient ventilation and diffuse light.

It is usually enough to water sunflowers once a week. Be sure to water them thoroughly and loosen the soil. In winter, you only need to water it once before winter comes, and then you don't need to water it anymore.
