pods on sweet peas
If you're trying to save the seeds from sweet peas, harvest the pods as they turn brown, but before they split open and spill their seeds. You could also place a little bag around the pods to catch the seeds in case the pods split open. (Often they'll split open if touched when ripe.)If they are hybrids, the plants that develop next year will be a mix of types.
