Question of the Day: When To Harvest Red Bell Peppers?
Quick Answer: The best time to harvest red bell peppers is one week after they have turned completely red.
Bell peppers go through color changes as they mature. Most varieties go from green to yellow and then, when fully ripe, turn red. As they ripen, they become sweeter, less bitter, and higher in nutrition.
Red bell peppers are considered fully mature and ready to be harvested once they are entirely red. If you can exercise a little patience, though, and give them a few extra days, you will be amazed at the difference in taste one week can make.
