How Plants Communicate With Each Other

You might not hear them, but plants are talking. Loudly.

For those who just rolled their eyes in disbelief, please read on as I am telling you, Plants can Talk!

We often think of plants as passive, you know, just hanging around, growing quietly and photosynthesizing in peace. But whilst plants may seem silent and stationary, they actually have their own intriquing ways of "talking" and networking.

That's right, under the calm plant surface (and sometimes above it), plants are constantly sending messages to one another.

Not with words. Not with sound. But with chemistry, electricity and even networks of fungal “internet.”

Here’s how the green world is way more chatty than we ever imagined.

🧪 1. Plants Talk Through Chemicals

One way plants can communicate is through chemicals: when a plant is attacked by insects, it can release airborne chemical signals (volatile organic compounds) that warn nearby plants. Essentially they are making a botancial distress call.

Example: A wild tobacco plant being eaten by caterpillars releases compounds into the air. Neighboring plants detect this and begin ramping up their own chemical defenses — like producing bitter leaves or toxins.

This is called allelopathy, and it’s essentially a plant yelling:

“Danger, danger, danger. Get ready.”

Is it just me that is picturing Danger, Will Robinson!! :)

Some plants even release specific chemicals to attract the predators of whatever is eating them! Yes, some plants are out there being backup assassins. How clever is that!

🌐 2. The Wood Wide Web

Another way that plants communicate is underground.

Beneath forests, there’s an underground fungal network, scientifically called mycorrhizal networks, and casually known as the “Wood Wide Web.” It is, essentially, the secret internet of the forests.

These fungi connect the roots of different trees and plants, allowing them to exchange nutrients, chemical signals and even stress alerts.

🌳 Mother trees (large, older trees) have been observed nourishing their saplings by sending them sugars and nitrogen.

🌲 Injured or dying trees can even “donate” their remaining resources to nearby plants through the network.

Cool, caring and considerate all at the same time! Nature is amazing.

Recent studies even suggest that plants can emit and respond to sounds.

It’s not just survival — it’s beautiful natural co-operation.

⚡ 3. Plants Use Electrical Signals (Yes, Really)

Some plants can transmit electrical impulses, much like nerves, plants send internal alerts — just slower and less dramatically than in animals.

When injured, a plant may trigger a signal that travels through its tissues and initiates chemical defenses or changes in growth behavior.

Example: The Venus flytrap only snaps shut when two hairs are touched — because it waits for electrical confirmation before reacting. Basically, it's waiting for confirmation that its next move is worth the energy.

👀 4. Plants Can “Eavesdrop” and Learn

Some studies suggest plants can pick up on chemical cues from unrelated plants and adjust their behavior accordingly — even if they’re not being attacked themselves.

There’s even evidence of “memory” in root growth patterns and preference based on past experiences.

Plants don’t just exist. They listen. They adapt. They make choices.

🧠 Genius Drop

While plants don't have brains, evolution has wired them with communication channels to survive.

Plants may not speak in words, but they communicate with precision, intention, and complexity.

They warn.

They share.

They respond.

And in their own special language of nature — they listen.

It's a weird and wonderful thought that a forest is not a collection of isolated trees, but a connected community quietly chattering away in chemical and electrical signals.

So next time you walk through a forest or water your houseplant, remember you are in the presence of quiet geniuses.
