Some time back I posted asking if peppers cross pollinate (they do). Since then my plants have started to produce. I have Cubanelle, Sweet Banana, Cayenne, and NM Sweet Jim. Some of the peppers are 4-5 inches long but still very green. Should I let them stay on the plant until they start to color? This is the first time I've ever fooled with peppers. They are all in pots and get good sun. They are watered about every other day unless they show drooping leaves.
