My bhuts produce less, but the pods are larger. I am also not being as aggressive with the hydro nutes in coco coir this year.
Not sure if South Texas is game for an in-ground overwintering or not. Ask a grapefruit orchard. If it freezes (as I know it occasionally does there), the plants are probably toast. If it doesn't and/or you cover them, I bet you'll keep on rockin' it.
Cool. After I posted that it occurred to me that you are probably already aware of the Austin native Chiltepins.
