When planting it is important to know the difference between seeds that point upwards or downwards. How deep to plant sunflower seeds isnt nearly as important as how far apart. As a plant begins to grow an embryonic root emerges from the seed termed the radicle or primary root.
Cutting your sunflower seeds Once your sunflowers have dried you should cut the stalk with sharp tools about one foot. In nature most seeds end up facing any old way and they still germinate. If it is pointed upwards the root and stem has to change direction which uses a lot of energy stored in the seed and decreases the vigor.
The embryo tap root emerges from the pointed stylar end and the natural method of growth is for this root to make a turn and grow downward see the illustration This bend formed by the downward curve of the taproot is what emerges from the soil and the friction of dragging the cannabis seeds upward helps the new plant to loosen and cast off the seed case when it breaks through the surface. Spacing depends on the size of the sunflower variety but as a guide you should space large plants up to 1m apart or smaller growers around 30cm apart.

In fact though seed orientation really makes little to no difference. It needs to be noted which end is downward. They sure do because roots of most plants always wind up down there in the soil not climbing up the stems towards the sky.
The radicle seed root will always grow downward showing positive geotropism while the shoot. Whether a seed is sown upside down right side up or on its side it has the ability to position itself so stems grow upward and roots grow downward. In order to ensure better growth when planting it is better to put the tip part downward and the large part upward because the tip part will grow roots so as to tie the soil tightly and then the growth will be more smooth.
