Could be that the bottle wasn't new and the H2O2 had already slowly transformed into mostly water... I don't recall if the plant survived the crown rot)

Yet another good question. Yes, why was it a frequent recommendation? I've never used it on a plant, and had stopped using it on my kids boo-boos around 25 years ago. From what Ray says above about the 3%, it sounds mostly ineffective, as opposed to being caustic to the plant. Hmmmmm.
