Well, Rick, I surely will post an update, if I get that far! But don't get your hopes up too high, okay? It may turn out to be more labor intensive a pursuit than I am ready for at this stage.
Good point about the little leaves, too, and that is how this spinach was harvested anyway. I never pulled any mature plants until just today when I pulled them to the compost, LOL! But those outer leaves did get pretty large, actually, and still tender and sweet for a good long run. I started another small batch of seeds, too, but it turned so dang hot I don't want to try to nurse them along. (Last year was consistently five to ten degrees cooler than it's been since the beginning of June here.)
The seeds in my library are likely to be predominantly zinnias and cleomes and cosmos and easy stuff like that. Although I do have that one Mizuna plant going nicely to seed right now; those would be easy to harvest. But probably I will let the birds have them.
