Adam has been watching this particular clump of bananas for weeks and weeks. He's gotten pretty good at judging when to harvest them. He waits for the individual bananas to plump out. Then he watches for signs that the birds or rats are interested. They can tell better than us that the fruits are nearing ripeness. In a matter of days, many of these individual bananas will begin turning yellow.
We have numerous clumps of Williams bananas on the farm. Since they produce very large bunches, they are worth growing for livestock feed, if nothing else. We usually don't eat them ourselves. But we have used them for trading and selling. I guess not everyone is as fussy about bananas like we are. Adam admits that he's become a banana snob too.
