Question of the Day: When are red bell peppers ready to pick?
Quick Answer: Red bell peppers are ready to pick when they have entirely turned red but are best left for a week after the color change has completed. The added growing time allows them to pack in more nutrients and get a little sweeter and crisper.
It can often be difficult to tell when the peppers stop changing colors. A trick that many experienced gardeners use is to take pictures each day at the same time and from the same angle. This creates a timeline that makes any shifts in appearance very apparent.
