Yeah, JoAnn, nobody would think that's not dirt, and if they did, they 'know your secret.' Bravo!
Forgot to add above, I also make banana water for potted tropical plants when they're outside. Pureรฉ in blender, dilute with water (I usually share 1 peel with 2-3 gallons of water.) Haven't tried it on cacti/succulents, but the 'regular' plants love it. If we ate more 'nanas, I would put it on ground plants too.
