What happens if you bury a banana?
Burying the banana peels in the soil under a plant can slow down the process that breaks down the peels and makes their nutrients available to the plant. What happens if you put a banana in soil? Banana peels can be placed directly onto pot plant soil, or around the base of your garden as mulch. As they decompose, they will release nutrients into the soil to feed plants. If using banana peels in your garden, place a single layer straight on top of the soil, being sure not to let them touch the plant stem.
