How to Sow Poppy Seeds:
From late fall to late winter loosen enriched garden soil down to a 6" depth. For zones 3-7 it's best to direct seed into your garden after your first freeze in the fall. For zones 8-9, or mild zones like California, you will get better results if you cold treat your seeds (see below) and sow them during the winter.
