I am not suere if you can help me with this question but I will try. I am growing some 'Bhut Jolokia' peppers. The plants are yielding OK. I read on a website somewhere that the plants will yield better the second year. It also stated that I should bring them inside and place them near a south facing window. However it did not say if I cut the plants back or should I simply leave them as they are? Any other suggestions you have would be appreciate also as far as increasing yields.
Generally speaking, chile plants lose some amount of vigor every year, so I am really skeptical of that theory. If your plants are in containers, they will survive in a south window during the winter and bear fruit that have already set; however, the weak winter sunlight will not stimulate more flowering and fruit setting.
Prune the plants in the spring and gradually place them in full sun outside.
