You can pick the chili peppers about 45 to 55 days after you see them bloom. Feel the growing chili peppers and see if they feel thin or if they feel as they should, somewhat firm.
Another clue is the color of the pepper. Most varieties turn red once they're ready to harvest. However, if your variety is supposed to turn orange, then you would wait for it to turn orange. If it's supposed to be green and it’s turning red, however, this could mean you allowed it to stay on the plant too long.
Also, the more you harvest peppers, the more the plant will produce for you.
i always pick my red chili peppers when they turn red, or can you be more specific about exactly what chili? there are lots of red chilis. the more you pick, the more they put on. at least that has been my experience. :)
