Oh yeah, that is who does seed-keeping. It’s kind of an anomaly that at this time, in this place, there are so few people keeping seeds.
Around the world, it’s still such a common practice. We’ve benefited a lot, since about 100 years ago, from the increase in small-scale seed companies. But in the 10,000-year history of humans growing food, domesticating food crops, that is the centerpiece of the work: making sure you’re leaving some of your harvest to go to seed so that you have a crop the following year.
So it’s certainly something regular people do, and I’m hoping more and more people get back to that.
