I ran across this a few months ago about pepper spacing. This is radical to what I have been doing all this time (12 " spacing) and thought I would give it a try with 6 of my pepperoncini plants in a corner of 1 of my raised beds.
We'll see what is up. And who would have thought that spreading out your thumb and pinky would be 9"?
