Seriously... nature is going to do what it is going to do. All we can do is help it along. Maybe the night-time temps are wrong. Maybe the day-length isn't right. Maybe the wine at dinner was a red wine served with chicken? Who knows these things?
You will notice that I'm very boring with my garden. I may add one or two things a year to the mix. Romas will be my tomato. I'm happy others have luck with all the varied types. My peppers are jalapeno and (as of this year) NM chili. I rely a lot on what I harvest, so I find something that works for me, here, and figure out when and how, and that's it. I'm not going to the grocery store if I run out of onions. I just can't afford to.

I understand you grow what works in your spot. You have had time to know what works best - I haven't. I'm in the shake-out time when I don't know what is going to grow exactly right for this space.
As you know, I have high brick walls around this garden and that changes the nature of the atmosphere in this space. Heat is emitted from the brick when the sun goes down. Nighttime out there is of a higher temperature than another space of equal size without brick walls.
So part of the problem is, which plants will grow best in this space, and I don't know the answer to that.
