A Banana a day keeps potassium deficiency at bay…or something like that!
Roses love potassium. Save up your banana peels over the winter for spring feeding by simply popping them into a freezer bag and then thawing just before use. Others recommend spreading them out to dry but I prefer putting them in the freezer. Fruit flies seem to hatch out of the peelings and after a few weeks our house is thick with the little flying fellows. If you dried the peels in a dehydrator chances are this wouldn’t happen.
However you save your banana peels for your roses they’ll thank you in blooms. Simply drop a couple banana peels into the planting hole or chop them up and work them in around the roots of established roses to provide a much appreciated dose of potassium.
Just be sure not to slip on them
