How to Harvest and Store Sunflower Seeds

Cut the sunflower heads, with 2 feet of stalk attached, as soon as the backs of the flowers start to turn brown.

Hang the heads in a dry, well-ventilated spot until the seeds have completely dried.

Rub the dried seeds from the head and remove the hulls.

Place the hulled seeds in plastic bags or storage containers and keep them at cool, dry room temperature for three to four months.

Store them in the freezer for up to a year.
