A childhood belief about plants

When I was younger I either heard someone say or saw on tv that if you speak to plants it's good for them. So when I would walk home from school I would stop in front of my house and talk to our tree(mind you, the tree was probably done growing). I would tell him he was the best tree on the street and that he had the greenest leaves. When fall would come around and the trees would start to lose their leaves, I would root him on. I'd tell him he was the strongest and toughest tree, and not to give up his leaves yet. Like it was some sort of contest. Lucky for me it was a healthy tree or I would have had a lot more disappointment in my childhood. As a red sox fan, I think I'd had enough(until last year!)
