After reading about banana peels helping roses, wonder what effect they would have on houseplants - would they have an adverse reaction to the plant? Thanking in advance for any help.
I leave them whole, and just bury them about 6" or so away from the base, an inch or so under the soil line. I've even buried whole bananas that did not get eaten in time.
Banana trees in the wild digest the rotted fruit and the potassium helps the trees produce more fruit. If you have a potted banana tree in your home, it is a good idea to feed it in this way every once in a while. I don't know if this applies to all house plants but potassium is contained in plant food.
I pureed a banana peel in 4 cups water and put a bit on several different houseplants. So far, I've had no adverse affects. I did use an organic peel so I can't comment on one that has the fungicides and mold-retardants on it.
