Subject: Why put soap on trees?
My wife and I just took a walk through a local "conservation" area in
Southeastern Pennsylvania. We noticed that someone had tied a bar of
SHIELD (tm) bath soap to a group of young trees and that this has
resulted in a bleached stain running down the trunk. (I don't know what
kind of trees they were, perhaps oak).
Is this some kind treatment or a fertilizer? What's going on?
