What's the trick to ripening green bananas at home?

I have same experience. It took three weeks for the bananas to become soft, not ripe. I put them in garage where the temp is usually 80 in the afternoon. it does not work. I am guessing some chemicals or fertilizer is the cause.


Try putting them in a paper bag. It concentrates the ethylene gas.

Many supermarkets have ripening rooms to process them to various stages.
