A friend in my office has a prayer plant on her desk and I ran my finger down the leaf to see if the plant would react. She told me not to touch the plant because the oil on my hands would kill it. Is there any validity to this statement? I had washed my hands with soap within the hour before touching the plant, so I'm not to worried about hurting this individual plant.
Personally, I think it's an Old Wives Tale. Am I wrong?
