Peaches might appear to have a smooth outer texture from afar. But you will notice a crease when you hold one in your hands.
Peaches have a crease because they have to release the pit (the seed) so it can germinate.
Why do peaches have a crease?
The line on a peach is called a suture or seam. For instance, water stress will result in a deep suture.
What Is the Line on a Peach Called?
Your peaches are possibly dimpled because stink bugs attacked them. The damaged area will not grow, and the fruit will begin to develop deep dimples.
Why Are My Peaches Dimpled?
Besides the suture, a peach may have cracks. But unlike the suture, cracks are not there to ease the release of the pit.
