I had the intuition: if I do not harvest these bananas on my schedule, they would do it on their own. And so they did. I came home, looked out the kitchen window, and there was the entire story laid out. Maturity. Gravity pulled them down.
In these two images you can see what maturity means to a banana plant. The bananas are not ripe, but they are heavy enough to pull the entire plant down to the ground.
Normally I would have supported the bunch of bananas with a bamboo pole, then carefully chop the bottom of the trunk so the entire structure slowly makes its way down. Even then, no matter how careful I might be, the structure might come crashing down. And thankfully the bananas are still firm enough that almost no damage is done to them. A few got knocked off, but even those will be fine in a couple weeks when they all start turning yellow. Until then, that entire bunch sits in the dark of a tool shed.
