Which end of sunflower seeds is facing up?

When planting sunflower seeds, point down, so that the roots will come out from there and take root naturally. If you don't want to bother, you can just throw them down or lay them flat on the soil. Sunflower seeds do not need to be soaked in water before sowing, and the sowing time is selected from March to April every year, and they can germinate in a warm environment for about 10 days.
