If you eat lots of bananas you end up with lots of banana peels. Instead of throwing them out or even composting all of them you can turn them into a potassium and phosphorus rich fertilizer.

Steps

    • Place the banana peels on the tray with the outer skin facing down so that they don't stick to the tray.
    • Save energy by piggy-backing on your normal oven usage. Don't turn the oven on just to roast the banana peels. Just leave the tray in the oven until you're cooking something else.

  • Question
    What happens to the chemicals that were used on the peel in shipping?

    Community Answer
    Depending on the chemicals that were used, they either evaporate, or decay into a non-toxic, brine-like substance. Completely harmless. However, if you want to be on the safe side, you could give them a wash in hot water to sanitize them.
  • Question
    Is necessary to place them in the oven, or can I just let them dry in the sun?

    You can just throw them in your garden as is, although burying them is a better idea. Oven baking speeds up the drying process and kills pathogens.
  • Question
    Why do I need to cook it?

    Community Answer
    You do not need to cook it. The whole purpose of cooking it before letting it rot is because it will decay faster if it is cooked.
