Does Playing Music Benefit Plants? Exploring the Evidence.

Do you serenade your plants? As a botanist passionate about houseplants, I often get asked this. The idea of playing music for plants gained traction in the 1960s, alongside the rise of “music for plants” albums, and it’s making a comeback online. But what does current research reveal about this enduring topic?

Clearly, plants lack ears or brains, so they cannot enjoy music in the way humans do. However, recent studies, including one study, indicate that they can detect vibrations in their environment and adapt their behavior accordingly. For instance, mouse worms exposed to the sound of caterpillar chewing produced high levels of a defensive bitter toxin. Astonishingly, plants can differentiate between the vibrations caused by munching insects and those from wind or mating calls, activating their defenses only when threatened.

Moreover, plants react to the sounds of opportunity. Certain flowers, like tomatoes, blueberries, and kiwis, ignore the buzzing of non-pollinating bees and release pollen only when stimulated by the vibrations of specific pollinators. This response can be rapid; for example, evening primrose flowers show changes in nectar composition within three minutes of being played sounds of bees in flight: Rich in sweet rewards. Researchers even reported pea plants can shift their root growth toward the sound of flowing water.

Nonetheless, as anyone who’s heard a seven-year-old on a recorder can attest, there’s a significant distinction between noise and “music.” Experiments aimed at assessing music’s impact on plant growth yielded mixed results. A recent study found certain music tracks enhanced lettuce growth significantly, while alfalfa showed no improvement.

Another investigation into background noise discovered that sage and marigold plants exposed to 16 hours of continuous traffic noise daily exhibited notably reduced growth. Could this continual noise be obstructing plants’ ability to perceive vital sound cues? At this stage, that remains uncertain.

The takeaway? Recent studies reveal that plants are not entirely oblivious to sound; in fact, they are significantly impacted by it. Yet, much about the specifics remains unclear, so we can’t definitively predict which sounds, at what frequencies or volumes, will yield desired results. So before you consider blasting Katy Perry for your plants’ benefit, remember that they might not appreciate it—and neither will your neighbors.
