Just let them grow. :)
Bananas do not naturally ripen once plucked from the tree. Rather, commercially sold bananas are gassed with a special chemical that encourages ripening after they have already been harvested.
The warmer it is , the faster they ripen
As far as i know all Banana trees grow green bananas, and they ripen into yellow later on.
In a sense, they do. As bananas ripen, they give off heat and ethylene gas, which stimulates other bananas (and other fruit) to ripen.
I don't put my bananas in bags. Bananas will ripen with out a bag.
NO you cant they can ripen better if you leave them in the shade
u go bananas
For some reason, when bananas and other fruit (specifically apples) are settled together, the combination causes the bananas to ripen (and then OVER ripen) in a matter of a few hours. I am not sure why this is, just that it happens.
To ripen bananas faster, place them in a paper bag with an apple or a ripe banana. The ethylene gas released by the fruit will speed up the ripening process.
The gas that causes food to ripen is Methane - It's commonly used to ripen bananas on an industrial scale.
I think you mean an apple will ripen bananas or green tomatoes. The apples as they ripen give off gas that aids and speeds up the ripening of other fruits, like placed in a brown bag with bananas or tomatoes and other fruits. Apples stored in the frige crisper drawer will make other fruits ripen quickly, thus go bad before you use them too.
I am pretty sure bananas will ripen and/ or rot faster if they are contained in something such as a brown bag.
