my bell pepper plants (2) are not producing peppers

Question

They have good growth and plenty of blooms, but the blooms do not develop into peppers.

Answer 1

Normally, this signals a problem with pollination. The high heat and humidity in many parts of the country has been affecting pollination. Or, it could be plant pollinators are having trouble getting to the plants. Peppers and tomatoes are identical in how they pollinate so you can use the information in this article to hand pollinate the flowers:
