Neighboring bean plants will also emit the same VOCs even when they are not being chewed on by any predator. While the first plant with the aphids will eventually die or suffer from extensive damage, the others will be protected.
If you believe that it is the vibration that makes plants grow better when you talk or sing to them, then it should not matter what you say, right? A recent experiment conducted by the furniture maker, IKEA, begs to differ.
IKEA asked children to come up with an insult and a compliment and recorded them. They then exposed one plant to the recorded insults and another plant to the compliments. After a month, the stark differences between the two were very evident. The plant that was exposed to compliments flourished and was very healthy, while the one exposed to bullying statements wilted.
Because while there may be studies out there that prove plants love music, our voices, and sounds, these studies also acknowledge that plants actually respond to the vibration produced by sound and that they do not exactly hear the sound per se.
There is some scientific evidence that plants love the vibration you create when you sing or talk to them. These studies show that there is indeed a strong relationship between plant growth and sound waves. This means that singing or talking to your plant is beneficial if you want it to grow healthy, but only at certain decibels and frequencies.
Further research is needed to confirm and explore this relationship. The exact mechanisms have never been pinpointed. So what about the IKEA experiment then? Some people have taken this experiment as the ultimate proof that plants can indeed hear and that they have human-like emotions. How else can you interpret plants withering and dying at negative words? Psychology Today published an article written by author and anti-bullying movement critic Izzy Kalman. He also pointed out that the experiment was not carried out by impartial researchers but by an advertising agency.
Masaru Emoto. However, Dr. Going back to the MythBusters experiment, the researchers also looked into the effects of nasty vs.
They concluded that there was no difference between the plants exposed to nasty comments and those that are given compliments. In that controlled and more scientific setup, both plants grew to the same height and did better than those that were growing in silence.
The MythBusters experiment showed that plants do not care whether you cuss at them or dote on them. They just need the sound waves. It is apparent that plants love sound waves because these help them grow. But another thing that plants need is carbon dioxide, which we breathe out when we speak. One prevalent notion is that when you talk or sing to plants, you give them a good dose of CO2. However, Marini explains that while carbon dioxide does help your plant produce its own food, you might need to talk for hours to get a beneficial effect.
Given all the interesting things that we are learning about plants and how they respond to our talking and singing to them, it would be nice to look into how all of these experiments started in the first place. Who was the first person to even think about the possible effects of chatting with plants or singing to them? By cultivating plants we can continue to cultivate our knowledge of the natural world and arm ourselves with more defenses against disease and infection.
Brethour Mental Health. Studies have proven that people who spend more time outside in nature have better mental health and a more positive outlook on life. People who spend more time outside in nature have a significantly more positive outlook on life than people who spend a great deal of time indoors. People who spend time outside every day are less likely to be depressed or stressed, and thus have fewer burdens on their mental health.
Perceived Quality of Life. People associate beautifully landscaped areas with a higher quality of life. This is important in attracting businesses and sustaining growth in the community. People associate living in areas with a great deal of natural beauty with a higher quality of life. A high quality of life, in turn, benefits the entire community, because residents spend more money and positively affect the economy and social pulse of the town and can also attract new businesses.
Thriving communities are ones in which natural beauty is appreciated as a part of an overall high quality of life, which is why installing landscaping is crucial to both the success and happiness of the individual and the public. Neighborhoods with beautiful parks tend to have less crime. This is due in part to the effect that parks have on a community; parks give people a reason to come together and become a tight-knit community.
People who care about their neighborhood parks are much more likely to get politically involved when businesses threaten to downsize them. Increasing political activism in the community is another positive outcome of cultivating a love for neighborhood parks. Neighborhoods with beautiful parks and landscaping have reduced crime rates. This is due to the increase in community cohesion that occurs as a neighborhood rallies around a beautiful local landmark.
When residents feel greater pride in the beauty of where they live, they are much less likely to detract from it either by graffiti or endangering people within it. Communities that choose to clean up their parks and beautify crime-ridden neighborhoods have less crime and fewer criminals to deal with. Parks can positively affect the community be reducing criminal acts and bringing residents together.
Cohesion in the community is critical to the success of the community as a whole, and this can be achieved through unifying people around a park or botanical garden.
Parks decrease incentives for people to commit crimes in the community, and at the same time help to bring neighbors together. They can also increase local political activism. As businesses and urban expansion threatens to downsize parks in the community, more and more people are banding together in a political effort to save their parks. Parks inspire people to come together and fight for what they know is holding them together as a community. Reduce Stress.
Studies show that people who spend time cultivating plants have less stress in their lives. Plants soothe human beings and provide a positive way for people to channel their stress into nurturing. Participation in gardening and landscaping activities is an effective way to reduce levels of stress. In general, plants lack the machinery for thinking, Robinson argues.
However, information can be said to move around inside plants, via chemical signalling. The idea that plants can learn is also contested. One researcher attempted to replicate the results of a study on learning in plants by Gagliano and colleagues. However, they were unable to achieve the same outcome. In a published response, Gagliano and her team said that the methodology of the repeat experiment was too different from their own to produce a reliable evaluation of their earlier results.
Robinson says he does not discount the possibility that plants can still surprise us — but he insists that we should not try to compare their communicative abilities to our own. Or attempt to talk to them. He also does not downplay the size of the disagreement between researchers who argue that plants are cognitively endowed and those who say they aren't. This is not to suggest that there is an even split between these factions, either.
Researchers' ideas about the capabilities of plants differ in lots of ways and many scientists besides Robinson remain sceptical that plants are intelligent — a prerequisite for human-like communication, one would have thought. But Tony Trewavas, professor emeritus at the University of Edinburgh, takes a different view.
He says that, under a broad definition, plants can be considered intelligent because they clearly respond to stimuli in ways that improve their odds of survival. He likens this to a zebra that runs away from a lion. We have little trouble thinking of that as an intelligent response whereas the plant that kills off a patch of its own leaf to stop a caterpillar egg from hatching may be viewed somewhat differently.
Trewavas also points to the fact that trees rely on networks of microbes in the soil to help them locate nutrients — this is a form of communication between species. It's certainly thought-provoking. Is survival, by definition, proof of intelligence? Either way, the question of how one could talk to plants or decode vegetal utterances still hovers.
While plants can clearly respond to acoustic stimuli of certain kinds and at the very least can sometimes communicate chemically with various forms of life, many would argue that it's not the same as having a chat. Or even akin to the incidental, social vocalisations that occur in many nonhuman animal species.
Laura Beloff says that, while she is fascinated by the possibility, she remains sceptical of the idea that plants can talk. And there's the question of what we would actually say if we could have a conversation with a conifer?
