These are NOT high yielding pepper plants. I have grown with great success tomatoes, cabbage, kohlrabi, cantaloupe, cucumbers and I have two fruit producing mango trees and a half dozen dwarf cavendish banana trees that also produce though, like they say, it rakes a white for bananas to set up the flag leaf. I grow all manner of herbs. The point is, I have grown fruits and veggies and I never had luck with the red, yellow or orange bell pepper. I've tried them in my grow box, in the rich soil just outside my grow box (amended also with compost) and now in a container. Everything else does well, so I have to say it it is the plant. I find that once one bell pepper starts growing, the other blossoms and tiny peppers fall off. The bell pepper growing now is thick-walled and blocky, it will be a nice pepper once it finally turns red. But it seems for the duration, there will be no other peppers. To me, it's not worth going through all that if the plant can only produce one pepper at a time. I am now trying the Bonnie "organics" bell pepper, in orange. This may be different as the plant is taller, and now I have four tiny bell pepper plants growing, plus I see three others forming and then there are half a dozen blossoms and about the same number of buds. We'll see. I have grown them in spring, summer, fall... I think the way these plants are, the regular bell pepper can only make one pepper at a time. I hope Bonnie can find a way to remedy that. Yes, I use fertilizer and water appropriately, and mulch. Just can't get it together with this type of pepper plant.
