There are black spots on the stems of my bell pepper plants where the stems branch. Understanding and help will be appreciated. Thank you.

Bell peppers often have a purple-black coloration at points where stems meet, but if the black color is a solid black and the area is shriveled, this would indicate the black are is the issue. One thing that I can think of that could be causing the issue is a condition called stem scald, which normally happens on the main stem. What happens is a heat source can focus heat on a part of the stem and it wilts. It is known to happen when plastic is used and it focuses the heat onto a part of the stem.
