Enough for 2 batches
The peels could easily be composted, but I prefer to use them as fertilizer for my roses.
My favorite way to use the peel is to cut it into small pieces and freeze it before using.
Some google searching found other (interesting) ways to use banana peels.
1. When transplanting roses, place a banana peel (and some say a tea bag) at the bottom of the hole.
2. Put peels in a 350 degree oven and bake until crisp, than bury next to your rose bushes.
3. Freeze and put through a food processor than bury around your plants
4. Make banana-peel tonic. Cut the peels of a banana into a spray bottle and cover with warm water. Put the lid back on the bottle and leave for 2 weeks. The peels will ferment. Spray the rose bushes with this liquid.
I plan to give these other methods a try, and would love to hear from readers who use banana peels around their plants.
Be well and happy gardening.
