I don't think you're disagreeing actually. That's what I called intrinsic values (maybe used the word wrong?) - the mental and physical benefits of keeping the garden.
I have no idea how my labor time would work out factored into my crops, working the garden. You just can't add up the ten minutes here and there on certain tasks..
El Pollo, absolutely, comparing seed put down to edible picked can be amazing. That's a beautiful thing you've got there! Last year I planted three Rattlesnake pole beans and picked an incredible amount. Yes, tiny Brassica seeds can yield a huge amount.
If I liked peeling, blanching, cutting, canning as much as I like outside tasks, I'd be set. . but I don't so I'd have to pay myself too much right now for that.
Apologies for straying from the topic.
Yes, my collard plant did make new fresh good looking leaves this spring. And it is adding side shoots. I don't know what it'll do later, or what I'll do to it. But it is the best of 6 or 8 I started last spring- most died, two others are OK but not this big. So Keith, I think brassicas are not reliably hardy for us, but if one is now and then.. more power to you.
