Do plants grow better if you talk to them? The idea is pervasive in modern society, although it probably has its roots (no pun intended) in the work of Dr. Gustav Fechner, a German experimental psychologist, who in 1848 suggested that plants would thrive if given attention and talked to. Since then, opinion (and experiments) seems to have alternated between confirming and debunking the idea, though that hasn’t stopped keen gardeners (such as Prince Charles) from having a chat with their gardens.

The Mythbusters team have always been happy to investigate this sort of folklore, and a number of years ago when they tested this they returned a verdict of ‘Plausible’ based on their experimental findings. Here’s the episode in question:

Now, for those that are interested in the topic, the Mythbusters currently have an interactive, online experiment running in which two plants are being monitored, one of which is being ‘talked to’ by a synthesized voice which is reading aloud tweets sent to the plant. It’s not exactly scientific, given it seems to be a sample of only two plants, but a neat set-up all the same:

Does talking to plants help them grow? Become a MythBuster and find out. Tweet a message, and your words will be read aloud to the plant. Go ahead, get something off your chest, wish it well, or just pass along today’s musings. The plant doesn’t care; it just wants to hear from you.

As I write this, it seems that plant being talked to has definitely grown more than the plant sitting in silence. Is there an effect, or is it pure chance? If there is an effect, what causes it? Do sound waves encourage growth (see this recent story for more)? Is it any sound, or only certain sounds or frequencies? Or is it a magnetic field from the speakers surrounding the plant? What do you think?
