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.
So far my red bell pepper plant is producing good peppers. I noticed on two peppers a light brown spot that is actually gooshy to the touch. I live in Arizona. I have had them in an area that is sunny. I recently moved them to a shadier spot. Is the sun affecting it or is it too much water?
It could be sun scald, which is caused by sun that is too intense. Providing a little shade should help.
The bell pepper turns brown, then mushy, and eventually rots off. How can I stop this?

I bought a yellow bell pepper plant and planted it in a large pot a few days ago. I have a combination of half Miracle Grow and half in-ground soil for veggies and herbs. I noticed that at every branch from the base, there is black and a tail at the end of each new pepper. Is this normal?
Some peppers have a black tint on their stems, so this is normal. The tail, if I understand what you mean right, is simply the leftover from the flower and will fall away. If it does not,simply pull it off when you harvest.
I have red and green bell peppers that have developed brown spots on the fruit. I have them planted inside pots with the bottoms cut out in my garden. I water every morning. Is that too much? What could be causing these brown spots?
It sounds like your peppers have developed sunscald. This is a result of too much sun on the fruit. We recommend shading the pepper plant with a translucent cloth cover.

I recently discovered spider mites on some of my vegetable plants: tomato, bell pepper, squash, cucumber. I tried to spray with soapy water and the next day all the plants had leaves that turned black or yellow and wilted. What is the reason for this, and can it be fixed?
Many dish soaps are starting to add bleach to their mix. You need to make sure not to use a dish soap that has bleach.
I had my soil tested. The pH is at 8. 0, so it's very alkaline. I have lettuce, cucumbers and many types of bell peppers growing (orange, yellow, red). What can I do to amend the soil to make sure the peppers grow? Should I add some type of compost? I've read elemental sulfur (I think) helps but that won't affect the soil this year (very slow change, I believe). Help!
