Does talking to plants help them grow better?

It doesn't.It turns out that there may be some truth to the belief that talking to plants helps them grow, but not for the reasons you may think. According to ScienceNet, plants need carbon dioxide to grow, and when you talk to a plant, you breath on it, giving it an extra infusion of CO2. However, for this to have any real effect on your favorite fern, you would have to spend several hours a day conversing with it in close quarters.
