When and how to harvest sunflower seeds?

3. Harvest at the right time.
  1. Harvest when seeds are plump and developed.
  2. Harvest when flower petals begin to dry out and fall off.
  3. Harvest when the back of flower turns from green to yellow (if you are cutting the stem off to dry).

With that knowledge in mind, how do you harvest sunflower seeds to eat?

The seeds should be clearly visible. The best seeds for eating come from the larger varieties of sunflowers. Just cut away the flower head from the stalk, place the flower head on a flat surface, and rub the center to dislodge the seeds from the flower. If squirrels and birds can get to these seeds, so can you!

In like manner when should I cut off my sunflower heads?

Once your sunflowers have died back completely and the backs of the blooms are brown, it's time to harvest. You'll also notice the seeds are plump and somewhat loose. Cut the stalk with sharp scissors or pruners, about one foot down from the flower head, and place in a container that can catch any loose seeds.

Besides, what month are sunflowers harvested?

Harvesting Phase
Your seeds should be ready to harvest within 110 to 125 days after you planted the flower. This means that if you planted your seeds in May, your sunflower will die in early or mid-August and you should have ready-to-harvest seeds in late-August or September.
