Do cayenne peppers have to turn red before you harvest them?
No, you do not need to wait until they are red to pick them. They will have a slightly different flavor and less heat, but they are still tasty.
Do all cayenne peppers turn from green to red, or do I pick them green?
You can pick them as either red or green. they will be more fiery and sweeter if you wait until they are red.
I am growing cayenne peppers that were started from seed. The peppers have come along nicely but the peppers on one plant are spotted. The spot grows until the area is shriveled and dead. The spot is near the tip, but not ON the tip. The remainder of the pepper apparently continues to ripen but we have been picking the damaged peppers off the plant to try to keep it from spreading. Any suggestions?
It sounds like blossom end rot. This article will help:
This may be of help with the pepper problems:
I have two 5-gallon buckets full cayenne peppers drying on tables. How do I sort best from bad? I want to use blender to crush them.
It would be best just to do a quick sight check on them. As you will be putting them into a blender, you can just do a quick visual check for rot and mildew before you put them in the blender.
The leaves on my cayenne chili pepper plants seem to be going white and curly. Please can you tell me what is causing this and whether the plants are to be discarded?
Did you recently move your plants outside? If you did and the leaves are white and papery, then they were not properly hardened off and this is sun scald, which is a little like sunburn for plants.

If the leaves are white and powdery, this is a fungus. You can treat the plants with a fungicide and this will clear it up. Fungus normally comes about due to poor air circulation and moisture. If possible water from below and in the future plant the plants further apart.
I have 5 different varieties of hot peppers planted in about 12" pots. I noticed first on the cayenne peppers that once the blossom matures and a small fruit starts, the stem turns yellow and falls off. The plants have several blossoms and I noticed this starting on another variety. Four of the potted plants seem to drain OK. I enlarged the drain holes on the cayenne, which probably was too wet. Is there anything else I should do? Also, I sprinkled a very small amount of slow release flower and vegetable fertilizer on the top of the soil. Could that be a problem?
It actually sounds like it may be a pollination issue. Peppers are self pollinating, but things like high humidity, hight heat or very rainy weather can cause the pollen to stick and clump, which makes the pollination process difficult.
Try giving the plants a gentle shake once a day or so to help pollen get knocked loose. If you want to confirm a pollination issue, you can take a small paintbrush and swirl it around a few blossoms. If these fruit do not fall off, a lack of pollination is the issue.
Being 33% hard and 66% semi-soft, I split and deprecated the seeds. My question is part of the seeds were white and whole, the others small and black. I assume the black are not good for planting. Do I need to discard them or is there use for them? Not only do I want the seeds to plant, but I also want to use them on pizza.
I would just discard them. They will not germinate and their flavor for cooking will be off, so there is really no use for them except the compost pile.
