Does music affect plant growth?

The relationship between music and plant growth has been a long-studied topic. Many wonder about the effect of music on plants, which is popularly known as the “Mozart effect“. Indeed, this phenomenon has been the subject of research ever since scientists and hobbyists began exploring how sound vibrations affect plant development. Below, you will find all about the most relevant findings and what are the effects of music on plants so that you can apply it to your cannabis seeds cultivation.

Effects of music on plants: recent evidence and studies

Scientific interest in the impact of music on plants dates back to early experiments conducted by figures such as Charles Darwin. Despite the inconclusive results of his early studies, curiosity about this phenomenon has persisted over the years.

Among the first scientific experiments conducted was Cleve Backster in the 1960s, who demonstrated how plants can respond to sound stimuli through electrical signals. Also, these studies opened the door to a new understanding of plant sensitivity.

Other outstanding research 

Among other experiments, the influence of music on plant growth was explored during the 1970s, with one of the most eminent studies being guided by Dorothy Retallack, who organized a series of tests with plants and music.

This experiment consisted of exposing different plants to various musical genres for different periods of time. Among the results that stand out are:

• Plants given classical music grew toward the speaker, and grew larger and healthier.
• Those exposed to rock tended to grow in the opposite direction, with stunted growth, some even died. 
• Therefore, plants prefer certain types of music, suggesting a possible preference for harmonious frequencies.

Again, this pioneering research provided early confirmation of the effect of music on plant growth.

Following Retallack’s initial findings, other interesting studies followed. Eugene Canby conducted a similar experiment with wheat, finding that plants exposed to classical music grew 60% more than those not exposed to music.

The Mozart effect: fact or fiction?

The University of California study on “the Mozart effect” suggests that listening to the compositions of the famous Wolfgang Amadeus Mozart could enhance brain function and, by extension, had implications for plant growth. This study went beyond the human realm, raising the question: whether Mozart’s music could have a similar effect on plants.

Furthermore, there are several studies and research that support the theory related to music for plants, despite initial skepticism, finding evidence to support the idea that music effects on plants, which could have a positive influence. It has also been demonstrated how certain musical frequencies can be used for specific aspects such as germination or vegetative development.

However, this is a subject of much controversy among the scientific community and further research is still being carried out.

The impact of different musical genres on plants

Plants, like humans, seem to have preferences for musical genres. But how do they affect plants? This topic has been the subject of several scientific studies over the years. 

Which genera do plants prefer?

The following conclusions have been reached in different studies:

• Musical genres with a higher intensity and irregular frequencies, such as rock, heavy metal or electronic sound have a negative impact on plant development.

• On the other hand, slow and harmonious rhythms can help to improve crop growth. Examples are classical music or jazz.

This suggests that plants may be sensitive to the vibrations of music in ways that are not yet fully understood. Although more research is needed to confirm these findings and fully understand why they occur, it is clear that the effects of music on plants are not uniform. 

Different genres of music appear to have different impacts, and these may vary depending on factors such as plant species and growing conditions.

The importance of sound frequency

Specific studies have revealed that frequencies between 125 and 250 Hz are particularly beneficial for plant growth. This suggests that certain sound vibrations can stimulate fundamental biological processes in plants, as well as smooth and predictable rhythms. 

Thus, genera with higher sound intensity are detrimental to vegetative development.

Similarly, those with high-pitched tones or distortions can negatively alter the internal water balance within the plant cells themselves.

How does music affect plants?

The vibrations can influence the cellular protoplasm, consequently affecting the development and health of plants. Indeed, music, understood as a series of vibrations, has the potential to modify the growing environment in beneficial ways.

Professionals speculate that enhanced growth in the presence of certain music may be due to the positive influence on cell structure and function due to harmonic vibrations. Specifically they are :

• Cellular resonance: specific musical notes may resonate with the natural rhythms of plant cells.
• Stimulation of metabolism: harmonic music could enhance processes such as photosynthesis and nutrient uptake.
• Improving the acoustic environment: a pleasant sound environment could stimulate more vigorous growth.

Possible uses of music in crops

The practical application of music to improve plant growth covers several areas:

• Agriculture: music can be employed as a way to increase production without the need for chemicals.
• Urban horticulture: in urban environments, where environmental stress is high, music could provide a beneficial acoustic refuge.
• Nursery and greenhouse cultivation: the controlled implementation of harmonic melodies could optimize growth in early stages of plant development.

The strategic inclusion of music in agricultural practices not only has the potential to improve yields but also to do so in a sustainable, environmentally friendly manner. Studies in vineyards in Italy and South Africa have demonstrated this potential. This non-invasive method could:

• Improve germination and plant growth.
• Act as a natural repellent for certain pests.
• Potentially replace or reduce the use of harmful products.

On the whole, the exploration of the effect of music on plants continues to reveal great opportunities for growers, however more research is needed.
