Banana peels are 42 % potassium—making them one of the highest organic potassium sources. We don’t like to eat them, but your plants will love them.

Banana peels also contain:

  • calcium (which helps plants take up more nitrogen)
  • manganese (helps with photosynthesis)
  • sodium (helps movement of water between cells)
  • magnesium and sulfur (both helpful in the formation of chlorophyll).

So here’s how to make the easiest fertilizer for your potassium loving plants (eg. tomatoes and peppers)
