I was wondering what I could do with the 5 banana peels I had left over after making banana bread and went online and saw the posts on Earth Clinic about banana peels for warts AND how they are great rose food because of their high potassium! We have lots of rose bushes at our house. Yea! I baked the banana peels on 350 for about an hour until they were crispy (could have down it faster with the broiler, but didn't think of it in time). Then I put them in my morter and pestle and ground them down. Finally, I took a few tablespoons of the ground banana peels and dug them a few inches down into the dirt around all of our rose bushes. Cool!
