Re: Banana tree snapped in half with almost mature fruit!!
I’d just add that commercial grown Cavendish bananas we buy at the supermarket in the US are harvested at about 3/4 full, i.e., not fully mature, yet they ripen fine when when gassed with ethylene. If yours are close to filled out, they will ripen, on or off the plant. They might fill out more if left on the plant, as other folks mentioned.
