In 1986, Prince Charles stated in an interview that talking to plants was important, an idea that was widely mocked at the time. However, recent evidence suggests that plants are indeed able to detect and react to sound. Scientists have exposed plants to various types of music and found that certain frequencies can affect seed germination and crop yields. Additionally, plants can emit noises in response to different stresses. Furthermore, plants are sensitive to the vibrations created by insects, and exposure to these vibrations can trigger the release of defensive chemicals in plants, making them less palatable to insects. This research could have practical applications, such as using drones armed with speakers to warn crops of pests. Another study found that plants may be able to “hear” the sound of water and follow it to its source. This information could be used to address issues such as root damage to sewer systems caused by plants seeking water. Lastly, recent research has shown that plants can produce sounds when experiencing stress, such as a lack of water or physical damage. These findings could potentially allow farmers to monitor their crops’ health by listening for auditory indicators of distress. Overall, it is clear that plants are more attuned to their environment through sound than previously believed.
