Did You Know?
Flowers are known to grow faster when music plays near them.
Playing music for your plants may seem like a strange thing to do, but research suggests that any sound, including music, helps boost plant growth. Vibrations from sound waves seem to stimulate growth factors. In addition, sounds may not just impact growth; evolution may have given plants "ears" so they can hear warnings about predators.
Research has shown that any sound has the ability to stimulate plant growth. In one study, plants that were exposed to sounds for six hours a day showed more growth than plants in a soundless control group. However, that same research showed that while music helped plants grow, it wasn't more effective than non-musical sounds. In other words, plants don't distinguish between music and other sounds. However, music does help plants grow
The exact cause of music's effect on plants is unclear. It is thought that plants may have "mechanoreceptors" that respond to pressure. Sound waves are made up of compressed air molecules. In humans, mechanoreceptors in the ears are able to detect and distinguish sound waves in the form of pressure as each wave strikes the inner ear. If plants have similar receptors, they too could respond to the changes in sound waves, such as those from music.
Plants also seem to listen to the vibrations of one another. Plants that are near other plants tend to grow faster and healthier than those grown in isolation. Research suggests that plants may “talk” to one another via vibrations, and these communications let a plant know when it is safe to grow. Other research indicates that vibration from sounds such as music can turn genes on and off, indicating that plants may "listen" to their surroundings to know when to express certain genes. If scientists can gain a better understanding of this phenomenon, it is likely that sounds such as music could be used to promote growth.
