Yeah, our rose bush grew to about 12 feet in height last summer
before we pruned it. I had ground up a banana peel in a blender
and started doing that about once every three months. I noticed
the black spot and was told that is normal. Some of the last peels
I messed with have been sitting in a bowl for awhile and I noticed
a mold growing on them. I don't know if it's a good thing or a
bad thing, that mold (green powdery stuff), so was thinking, well
if it's bad I'll just throw in some grits because corn gluten reportedly
helps control weeds and fungus...



I suppose banana's potassium is helpful, beyond that I am unsure if you mean
the blackspot is caused by the banana.
