Q.When do the peppers come, develop, grow?
I have had my patio pepper for over 2 months. It is in a pot on the same side of the house as my tomatoes (which are planted in the ground). It seems to be growing well. It is getting taller and bushier. The flowers develop, but peppers never form. Am I doing something wrong? Or does it take a long time? My heirloom tomatoes (bought at the same time) now have good size green tomatoes on them. I realize, after some research last year, that they are 80-90 day plants.

This could be a few different issues including environmental, Nitrogen levels and pollination.
