First and foremost, the peppers, tomatoes are very sensitive to touch. Even when you are weeding them, you need to be extremely careful. Or else you may lose all flowers, or fruit pods. So whenever you want to weed your Pepper farm or wet them, it must be very slight touching, the stem in particular. They are very fragile when you see them with flowers. Not that, when you see them with yellowish colour. You can add Ash with water and sprinkle it morning and evening. For three days.
