Q.Sterile Peppers
What would cause chili pepper plants not to grow any peppers? The plants are healthy looking and have grown to about 18-22 inches tall. A couple leaves have holes in them, but that is about all. They are being grown in containers on my deck, which gets sun most of the afternoon.

It sounds like a pollination problem. This hot, humid summer has been hard on pepper pollination. These articles will help:

If you are not getting blossoms, this is likely either too much nitrogen or too little phosphorus. Adding some bone meal or other phosphorus rich fertilizer will help.
