What size pot would be sufficient if growing outside?I ask mostly because, depending on how hot your summers get, peppers can sometimes do better above ground in a pot than in ground. If it is a very hot summer they can do excellent in ground too. I had some bell peppers planted in ground last year during a scorching & wet summer and they grew fantastic. But that is really rare for my area.
We normally have cool summers, with maybe a week or two of 'hot' weather. Last year was very unusual.
