I planted three bell pepper plants in my small garden this spring. They were all doing well, but the other night, the plant that actually had a small pepper growing on it began to look wilted. The leaves drooped and the plant looked very unhappy. I thought it needed water, so I watered it; but that did not seem to improve the plant. Some of the leaves seem to have a bronzy sheen to them. What can be done to save this plant, if anything?
It sounds like it might have wilt. This article will explain more about it:

Will my bell pepper plants still produce fruit if a bird snipped the tops off? The plants haven't flowered yet and still have some leaves.
If it still has at least one set of true leaves, it should regrow. You will notice that it will grow bushier as a result. Some people actually deliberately pinch the tops of their peppers to make this happen.
I have recently noticed a brownish film on bell pepper leaves and spots on others.
This could be due to some type of virus or fungus, often attributed from pests. Neem oil will help with any pest problem, as well as fungus. Here is more info: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

I have a bell pepper plant in a raised bed and I noticed that where each branch extends from base, there is black. I planted these plants about two weeks ago. I did not start with seeds. Could this be a disease problem?
The plant could be in the early stage of blight-caused from a soil-borne fungal infection. It's also more prevalent in poorly drained soils and humid conditions. If it's just starting, fungicide may be helpful.

How much watering is needed in southwest US to grow red bell peppers?
Water the soil when it is dry on the top, which will likely be nearly once a day, perhaps twice a day on hot days. This article should also help: https://www.gardeningknowhow.com/edible/vegetables/pepper/how-to-grow-red-peppers.htm
Why are the leaves on my bell pepper plants curling in on themselves? They were planted the third week in April. They are watered regularly.
Peppers are susceptible to tomato diseases and I suspect that your peppers may have Leaf Curl. This article will explain more:

Are red bell peppers really matured green bell peppers?
Actually, yes they are. Bell peppers come in many varieties. Much like a tomato plant, these pepper plants have green immature fruit and red mature fruit. And, also just like a tomato, the mature fruit can also be yellow or orange. Therefore, these varieties are just left on the vine longer to color.
You can also visit Burpee's web site to see all the different belle peppers available as well as their colors. I don't claim to be an expert but I know that if I want red belle I plant red and if I want green belles I plant green.
No, belle peppers come in several different colors. Red, green, yellow, orange, white, and purple. Each offer a completely different taste with red being the sweetest that I have found. I can actually eat a red belle like an apple they are so sweet.
