I'm wondering if anyone else knows why my little red sweet peppers (I think they were called cherry peppers, but I lost the pot stake) have such tough skins. As soon as they turn red, the skins get tough and woody-looking and I'm picking them as soon as they have the red color, because they got bitter if I let them stay on the plant more than the day they turned red. They have good flavor, but such a tough skin, you can hardly chew through it. This is my first year to try this type of pepper, so I don't know much about them, but never had this problem with other peppers (sweet banana, green and yellow bell, and even jalapeno). Any advice is appreciated!
