Seeds that have been soaked should be covered with soil when they’re planted. When you cover soaked seeds with soil, their pods and hulls stay thoroughly moistened and will be naturally cast off as the seedlings push up through the soil. Otherwise, you’ll need to remove many of the pods and hulls manually when it’s time to harvest. One exception to this rule is sunflower seeds; for unknown reasons, covering sunflower seeds with soil seems to cement the hull to the leaf.
