A fundamental approach to the production of liquid fertilizer from banana peels:
Cut the peels: Once you have finished eating the bananas, cut the peels into many smaller pieces. When the fragments are smaller, the rate at which they will disintegrate increases.
The peels should be placed in a bottle: Put the chunks of banana peel into a bottle and fill it up. Either a bottle made of plastic or glass may be used.
Put in some water: Fill the container with water until the peels are fully submerged in the liquid. A little amount of space should be left at the top in order to allow for fermentation.
