The Science of Tree Communication

By Liliana Usvat

All over the world research is performed that prove that the plants in general and tree in special communicate. So when we threaten them or cut them they react. Plants have consciousness.


I will show few researches done around the world to scientifically prove different types of  communication. We’ve all heard about the benefits of talking or playing music to your plants.

Plants even have musical preferences — they apparently love Mozart but hate Jimi Hendrix.

Two new studies have proven that plants do at least communicate with each other in ways not previously understood by us. In the most recent study, conducted by a team at the Ben-Gurion University, pea plants have been found to alert each other to stressful situations.


In the experiment, the plants were placed close to each other, but not touching in any way. Some plants shared soil with those next to them, while others were completely separated. Next, a few of the plants were given drought-like situations, while others were kept healthy and watered.

The research in plant communication a collaborative initiative between the Centre for Evolutionary Biology at UWA, the Bionanoscience Lab at the University of Bristol and the International Laboratory of Plant Neurobiology at the University of Firenze (Florence). These research institures know that plants communicate through the

  • transmission and reflection of different wavelengths of light,
  • via mechanical contact and
  • the release of an extensive vocabulary of chemical molecules, such as herbivore-induced volatile organic compounds.
  • They are exploring the possibility of alternative pathways of interaction, primarily acoustic and magnetic communication, and their ecological and evolutionary significance.
  • Finally, we are studying learning abilities and memory in plants.
  • Just like many animal groups from honeybees to humans, plants are capable of sharing information amongst relatives and
  • solving problems as a group (swarm intelligence).
  • They are exploring the extent to which plants store and recall previous experiences (learning) and
  • then share this information to potentially enable collective solutions to challenging problems.


The evidence for plant communication is only a few decades old, but in that short time it has leapfrogged from electrifying discovery to decisive debunking to resurrection. Two studies published in 1983 demonstrated that willow trees, poplars and sugar maples can warn each other about insect attacks:

Intact, undamaged trees near ones that are infested with hungry bugs begin pumping out bug-repelling chemicals to ward off attack. They somehow know what their neighbors are experiencing, and react to it. The mind-bending implication was that trees could send, receive and interpret messages.

Rigorous, carefully controlled experiments are overcoming those early criticisms with repeated testing in labs, forests and fields. It’s now well established that when bugs chew leaves, plants respond by releasing volatile organic compounds into the air. By Karban’s last count, 40 out of 48 studies of plant communication confirm that other plants detect these airborne signals and ramp up their production of chemical weapons or other defense mechanisms in response.

Martin Heil, an ecologist at the Mexican research institute Cinvestav Irapuato said “The evidence that plants can somehow perceive these volatiles and respond with a defense response is also very good.”

Farmers might be able to adapt this chatter, tweaking food plants or agricultural practices so that crops defend themselves better against herbivores.

More broadly, the possibility that plants share information raises intriguing questions about what counts as behavior and communication — and why organisms that compete with one another might also see fit to network their knowledge.


Plants can communicate with insects as well, sending airborne messages that act as distress signals to predatory insects that kill herbivores. Maize attacked by beet armyworms releases a cloud of volatile chemicals that attracts wasps to lay eggs in the caterpillars’ bodies.

Plant-eating bugs, and the insects that feed on them, live in a world we can barely imagine, perfumed by clouds of chemicals rich in information. Ants, microbes, moths, even hummingbirds and tortoises (Farmer checked) all detect and react to these blasts.

Plants research

In the new study, Gagliano and her colleague Michael Renton showed that chili plants sprouted faster and were healthier, compared with those grown in isolation, when they were grown next to “good neighbors,” such as basil, that help inhibit weed growth and pests.


Remarkably, the scientists got the same result even when the plants were separated by black plastic so that they could not exchange light or chemical signals.

Somehow, the chili seedlings could tell what kinds of plants their neighbors were and respond accordingly. Gagliano speculates that the answer involves acoustic vibrations generated—either intentionally or not—inside plant cells.

“The vibration idea is the easiest one, and maybe the most intuitive because sounds travel very well in a lot of mediums,” Gagliano said.

Gagliano’s latest work is a follow-up to an experiment, in which her team showed that chili plants could similarly sense when they were surrounded by “bad neighbors,” such as fennel, that release chemicals that inhibit the growth of other plants.

How to listen to plants

The technology to hear plant bubbles explode is actually quite simple. Acoustic sensors designed to detect cracks in bridges and buildings catch the ultrasonic pops. A piezoelectric pickup, the same as an electric guitar pickup, goes through an amplifier to an oscilloscope that measures the waveform of each pop.

“We became fascinated with the thought of being able to listen in to the plumbing of the saguaro cactus,” said Lois Wardell, owner of Tucson-based consulting firm Arapahoe SciTech. Starting with a 3-foot-tall potted saguaro, Wardell and geophysicist Charlotte Rowe hope to distinguish between cacti drying out and those complaining about other environmental stress.


“We’re working on trying to differentiate these two signals: I’m cold versus I’m really thirsty,” Wardell said. “We’ve already managed to produce a few squawks.”

Living in drought-stricken Australia, Gagliano is also excited by the possibility of decoding drought signals. “We don’t know if these emissions are also providing information to neighborhoods of plants,” she said. “Plants have ways of protecting themselves when they run out of water, and they are really good at sharing information about danger, even if one sharing is one that’s going to die.”

“How many times have you sat next to someone who has their car stereo at full blast? You can really feel it pounding in your chest,” he said. Trees perceive and respond to touch, like wind or an animal passing on a trail. And like the wind, sound is a wave that travels through air.


In fact, a tree needs wind to grow, Frank Telewski,( a botanist at Michigan State University and an expert on how trees respond to wind.Frank Telewski, a botanist at Michigan State University and an expert on how trees respond to wind.) said.

“If you stake down a seedling, you do it a little bit of disservice, because a tree needs to perceive motion. It’s like physical therapy for the tree. If you stake it too tight, it does not allow the plant to produce stronger tissues.”

Researchers in China have shown they can increase plant yields by broadcasting sound waves of certain frequencies. Other groups have investigated how different frequencies and intensities of sounds change gene expression. Their studies find that acoustic vibrations modify metabolic processes in plants. Some of the beneficial vibrations also drive away pesky insects that munch on crops.

“Shamans say they learn from the plant’s sounds. Maybe they are attuned to things we don’t pay attention to,” Gagliano said. “It’s really fascinating. We might have lost that connection and science is ready to rediscover it.”

How Talking To Trees Can Soothe You


The energy vibrations that trees emit  are very soothing and calming to the human soul. If you’ve ever spent time in a garden, an orchard, or a forest, then you know how different it feels to be in the midst of trees, compared to being in a place devoid of them.

This is because trees absorb the negative energy from your body, and transform it into a positive one. And their vibrational properties facilitate metaphysical restoration, and free blockages in your psychic energy systems.

Trees are so well grounded with the earth, and tuned with the universe, that they can transform your energies for inner healing and cleansing.

Tree Communicators

There is a new science and Maia Kinkaid Ph.d. is at the edge of a new science she is able to communicate telepatically with plants and trees. Is there a skill we all had and forgotten?


She said “Telepathic communication with plants, insects and the Earth is absolutely fascinating and so informative in ways we would never imagine.” On her website she has a sample of such communication.

Tree Meditation

1.Find a nice spot by your tree, and be comfortable.

2. Close your eyes and listen to the silence. The more you attune yourself to the absence of sound, the more the sounds of nature will become clearer to you.

  1. Meditate on these sounds, paying attention to the rustling of leaves, and how the tree reacts to the movement of the wind.
  2. Inhale the clean, fresh air from the tree, and let it inhale the carbon dioxide that you exhale. Focus on this exchange of air, and feel the cleansing that it brings.

  3. Sense the positive energy that the tree emanates. Accept it; at the same time, let go of the negative energy in your body.

  4. Do this for several minutes each day. You might start with five minutes, steadily increasing the time as you become more comfortable with this practice.

In time, you will be more sensitive to the unique energy vibrations from your tree, and you will be able to sense the immense wisdom it has to share with you. Blog 101-365
