How long does bananas have to stay before you pick them off?

Bananas typically require about 75 to 80 days to ripen on the plant after the flower blooms. They are usually harvested while still green to ensure they can be transported without bruising. Once harvested, they can ripen off the plant over several days to weeks, depending on temperature and humidity. Ideally, they should be picked when they are still firm but have started to change color, indicating they are nearing ripeness.
