With the move my seed saving is not quite what it was last year. But that doesn't mean I haven't been saving seeds. Some seeds are easy. My dried beans are both the harvest and the seed. So I have plenty of seeds for next year if I can keep myself from eating them all. They do need to be frozen for a few days to make sure all the weevils are dead, but before that they have to be absolutely dry. They are dry when they shatter when hit with a hammer. If they mush, they aren't dry enough. I've also started harvesting my coriander. It is finally ripe. I never picked any leaves (cilantro) as I wanted the seed to plant for next year.
The marigolds are so easy. I just waited a while and then picked the dried heads. The ones that I grow are Ground Control. They aren't the showiest of marigolds, but I love them as they keep the nematodes down. And though not as showy as one bred just for ornamental purposes, I think they are very pretty draping over the side of the rock wall. They like to grow up, but I just beat them down breaking their stems a little. They don't seem to care at all.
I didn't bother to save pepper seeds as they cross readily and I haven't isolated them at all this year. But the tomatoes are easy. They rarely cross and they are so easy to save. You just squeeze out the seeds into a bowl. Cover the bowl loosely to make sure it stays wet. And let them ferment for a few days.
They look pretty bad and smell bad, but it gets rid of the gel coating around each seed and is supposed to kill some diseases. After it looks just disgusting, you can pour off the gunk and rinse the seeds off and let them dry. I saved seeds from Black Prince, Heinz, Cherokee Purple, and Romeo Roma. I need to save some from GabrielleAnn still and maybe Amish Paste.
