I seem to have no problem at all growing Sweet Banana peppers in large quantities, and these go a long way toward meeting our sweet pepper needs, and will continue to do so.
However, I have a long history of frustrating results with bell peppers, or peppers that I have been told can be used like bell peppers. Sometimes we need, or want, a thick-walled dark green or red sweet pepper. This year, I have Corno di Toro growing, a variety I have heard good things about (including "use like a bell pepper", even though it is a bull horn type). We have had exactly zero peppers from CdT (and no fruit set), while Sweet Banana growing next to them are barely keeping upright with so many fruit! Both varieties started from seed at exactly the same time, developing next to one another. The soil is prepared exactly the same way for both varieties, same full sun conditions, plenty of water for both types, etc., the plants of both varieties are chest high, blooming, just no production from the CdT at all. Yet, two feet away, there is a Sweet Banana that has multiple fruits 6 to 8 inches long, as if to say "this is how it's done... this is how you get on with it". The same thing has happened in the past with California Wonder.
Any suggestions as to what might be going wrong for me with CdT or bell peppers? Is there a cultural element that I might be missing? Is there a different bell pepper variety (or other pepper that can be used like a bell pepper) that I should be trying that is more of a sure bet in terms of production?
Any suggestions appreciated, thank you.
