The bell peppers got to be around 14” tall and a couple of them produced well enough, but the peppers were mostly sorta small.  The poblanos were late in the season and I only got a 4-5 peppers.  They were also on the small side.  This year I’d like to try both again, but add some jalapeños in there as well.  I hear there is a no-heat jalapeño so I might grab one for my wife (she is sensitive to spicy).  I’ve thought about growing pepperoncini as I really like the taste, but can’t seem to find seeds or seedlings.
Another plant is like to learn to grow is garlic.  I might try my hand at onions, but I am going to really look into garlic.  I love garlic and I hear it is awesome and tastes even better than store bought.
