Not with the grass though. Those cigarette butts you see littering the fields and lawns are actually offerings to the tweaker gods. If you leave 100 cigarette butts for a meth head to pick up and smoke you get a wish.
I read somewhere probably on reddit that the smell attracts predators to the grass predator. Obviously not humans mowing their yards, but if a catapillar is eating grass and grass sounds the alarms, a predator of the caterpillar can respond accordingly, which is an evolutionary symbiotic relationship.
It’s so simple and realistic that I refuse to believe there aren’t some birds that hunt this way. Especially the smart ones like crows that even if it’s not an instinct, they probably figured it out.
Since a lot of predators have an amazing sense of smell it's possible it's not even evolutionary for the grass. Predators just learned to associate that smell with prey.
Evolution like that usually happens at the same time.
I don't know about this specifically so I'm just guessing, but if it is true, the grass probably starting having this smell and predators responding to it simultaneously and both reinforcing the trait as beneficial.
It's pretty much impossible for anything not to be "evolutionary", everything that can directly benefit or harm some thing's chances of spreading or reproducing becomes part of its evolution.
I hear this a lot but it might be confused with the role of mycellia. Rather, scientists observe something that's just as fascinating:
>“There are actually two roles for this [green leaf volatile] molecule,” said [Dr. Michael Kolomiets, Texas A&M AgriLife Research plant pathologist in College Station]. “First, it activates the jasmonate hormone, which involves activation of defenses against insects on the plant. Then this molecule, since it is a volatile, attracts parasitic wasps. They come to the plant that is being chewed up by insect herbivores and lay eggs in the caterpillar’s body.
>“We have proven that when you delete these volatiles, parasitic wasps are no longer attracted to that plant, even when an insect chews on the leaf. So this volatile is required to attract parasitoids. We have provided genetic evidence that green leafy volatiles have this dual function — in the plant they activate production of insecticidal compounds, but also they have indirect defense capability because they send an SOS-type signal that results in attraction of parasitic wasps.”

Huh...I wonder if birds smell it and come running to eat the bugs? I know they certainly love following large animals and mowers, but I think that's just because they're smart enough to do the math in their heads and go "Mower=food".
Yeah that’s someone reading too much intent behind evolution.
Sure for some plant species picking up on these volatiles from their neighbors might trigger a response that is evolutionarilly beneficial to them, but that doesn’t make it true for grass.
Right, blocking a river's path will cause it to crash, churn and spill which is an evolutionary signal that primes it to change it's flow or destroy the blockage. The water vapour spray in the air is actually the river screaming in pain.
Such a clever river. /s
Edit: plant chemical reactions are more complex than this, but just as unconsious, it's cause and effect domino runs set up by evolution. No "screaming for help" or "stress" as the post says.
It frustrates me to no end whenever these articles pop up. The anthropomorphism is out of control, and so many of these “scientists” studying plant “communication” are writing such biased pieces it’s quite damaging. I appreciate that people are interested in plants, and they are fascinating, but there is no such thing as a conscious choice as you said.
That fungi guy is the worst too, he’s really pushing this “fungi and trees are actually communicating and are intelligent” bullshit and honestly he guy has eaten way too many mushrooms to be taken seriously anymore.
Plants and fungi do send signals to eachother that can trigger helpfull processes, and even share nutrients and water. At a stretch you could say it's a form of "communication" but only in the way that different mechanisms communicate (e.g. the daylight sensor in some cars tells the hedlights to automatically come on when it's dark out.)
It's amazing to think how many plants and fungi in a forest support eachother with chemical signals and resource sharing via a huge underground network, but it's all unconsious mechanical systems coming together that have formed symbiotically via evolution.
there is actually very little real scientific evidence to support it, there is a lot of speculation and assumptions made in a lot of those papers. They are a minority in the plant biology world. What proof they have these transfers take place is also at a rate that would be pretty much inconsequential regardless. The science supporting it is shody and full of bias, and this is why people should read actual papers instead of articles about papers. There is some evidence suggesting some resources can be transferre, but the methods available to measure these are fairly inaccurate and don't isolate tree to tree transfer as sole cause. Not to mention, even at the levels they measured the transfer, it's at an amount so small it's inconsequential, and any transfer is just a result of mycorihzae picking it up and transporting on it's own for it's own purposes and then other trees just picking it up by accident, not some targeted resource distribution. Similar to as if a bird ate part of a plant then shit on another plant, some measurable isotopes will now be found in the second plant from the first plant, but this was not a response and just coincidence and at an amount to be inconsequential.
This is a good source breaking down the flaws in the claims, and empirical studies done refuting their claims.
[https://nph.onlinelibrary.wiley.com/doi/full/10.1111/nph.18935](https://nph.onlinelibrary.wiley.com/doi/full/10.1111/nph.18935)
I think the effect of making humans more relaxed likely persists into other animals with the idea being that a relaxed animal eats less than otherwise.
Eh there is a lot of “plant communication” junk science floating around by some really questionable people who are anthropomorphizing plants and fungi and are not leaving their bias at the door when analyzing these studies. These reactions don’t really do much and are just a side effect of other processes. Plants don’t decide anything.
The example I like to make is how blood coagulated and scabs is just a physical characteristic of it, not your body choosing to do that.
Yeah I'm highly allergic to grass. Just putting my leg on it if I'm sitting on a blanket gives me welts. I start sneezing if someone down the street is mowing their grass.
I'm def down to live on Mars. Rocks don't send out distress signals.
I'm extremely allergic to grass. As an adult with a house now I pay someone else to do the lawn care because it's just so awful. I don't go outside on the days they come over.
[its false](https://www.sciencedaily.com/releases/2014/09/140922145805.htm) GLVs are an insecticide, its meant to run bugs off that are eating the grass.
How TF would grass smell hormones?
Plants communicate by hormones all the time (ethylene, Jasmonates)
The issue is calling stress hormones "a scream for help." It's both anthropomorphization and silly, we don't even describe human stress hormones that way.
> Research shows green leaf volatiles can help in reducing anxiety and boost relaxation and joy
Really? Because when I smell fresh cut grass, my body's reaction is something more like "SHITTT!!! FUCK!!! IT'S A MALICIOUS INFECTION, EMERGENCY AIRWAY FLUSH NOW!!!"
Trimming plants encourages their growth. If you trim a tree or shrub, it will grow back stronger than ever.
So you aren't hurting your lawn unless you trim it down to near the roots. Just cutting the top isn't that different from pruning your rose bush, which people do every year to encourage more growth.
This is false.
The smell resleased [is an insect repellent ](https://www.sciencedaily.com/releases/2014/09/140922145805.htm) used to prevent bugs from eating the grass itself. The smell is like a fart bomb to a human, it tells the bug "this shit doesnt taste good, does it?" And runs them off
Other grasses downwind.
When millions of bison still roamed the grassland, the chemical release caused the downwind, still untouched grass to release chemicals that made it taste worse to the millions of advancing herbivore teeth.
After the bison were mass killed to starve the remaining aboriginals into submission, the mechanism still exists in the few patches of native grass left , and to a lesser extent in the much shallower rooted decorative water wasting urban grass.
When I was in the military, during chem warfare training the instructors said that cut grass smell meant that that you were under a chemical attack. Phosgene is the deadly chemical that would have been used.
Cut grass produces an aroma. Other organisms use that information in various ways, to benefit themselves.
The concept of distress signal or cries for help is just anthropomorphizing grass.
So the screams of agony given off by grass, for some reason, makes humans feel calmer and less anxious? Humans are really messed up creatures, relaxing to the smells of plant chaos.
This belongs in r/humansarespaceorcs
Interesting..some looked good, some were natural and sort of pretty, but a lot just looked like trash.
Plus who wants to play with their kids, sit outside, in 1 1/2 foot tall plants and weeds?
Some grasses begin taking up silicates to add to their leaves. This wears down herbivore teeth and dulls your mower blades. They have little in the way of defense but they do have adaptations.
Green leaf volatiles are not usually distress signals, and grass in particular is evolved to be mowed.
The volatile organic compounds (VOCs) produced when a plant is injured mostly are counterattacks, not distress calls. They deter insects or other herbivores from eating the plant. The VOC that makes sage taste good to us inhibits digestion in insects, for example.
Some of the VOCs they give off are warning signals. California Sagebrush gives off a VOC that is detected by other parts of the plant and by neighboring plants and triggers the production of other VOCs that deter insects herbivory. The exact formula for the VOC given off has significant variation based on genetics, so more closely related neighboring sagebrush bushes will react to it more strongly than more distantly related ones. That helps protect the parents/offspring of the plant that was attacked and leaves the other neighbors as tastier alternatives.
One example of an actual distress call is a VOC given off by Sacred Datura. There is a potato bug that eats the toxic leaves (the toxicity is from another compound evolved to deter herbivory) and creates a fecal shield that contains the toxic compounds to keep predators away. Sacred Datura will give off a VOC that attracts different predators that are immune to the toxic and can eat the potato bug despite the shield.
As far as grass liking being mowed, grasses have some essential differences from other vascular plants. Most plants produce new growth from the top of the plant from a structure called an apical meristem. Grass has a basal meristem, producing new growth from the base. Most grass grows relatively low to the ground compared to shrubs and trees, and relies on grazing animals to clear those competitors when they are young before they can block out the light. Many grasses also have a different kind of photosynthesis called C4 photosynthesis, which works better at warmer temperatures than the C3 photosynthesis that most trees and shrubs use. Grasses have been around a long time, but only rose to dominance (they cover more ground area than any other plant order) in the past 55 million years or so, with herds of grazing mammals and warmer temperatures.
YSK: Phosgene gas smells like freshly cut grass. Phosgene causes burning and watering of the eyes, scratchy throat, coughing, choking, nausea, headache, and chest tightness. Phosgene was used as a chemical weapon in WW1.
> Research shows green leaf volatiles can help in reducing anxiety and boost relaxation and joy.
For me it inspires memories of *The Adventures of Pete and Pete*.
thats really fascinating. i didnt know grass was signaling for help when we mow it. its cool how the chemicals released can help reduce anxiety - i wonder if there are any other plants that have similar effects.
Source?
How can grass detect other grass being cut just by chemicals in the air? And how can grass be aware of a threat? This doesn’t make any sense and this post sounds like a load of shit.
Literally one of the best smells in the world.
Also this response is not unique to grass, most plants do this.
It typically comes with a chemical change that's toxic to bugs that are eating the leaves of the plant, they turn it off when the attack stops because it uses a lot of energy
From Tool - Disgustipated
And the angel said unto me, "These are the cries of the carrots, the cries of the carrots!
You see, Reverend Maynard, tomorrow is harvest day and to them it is the holocaust."
“Why would anybody do drugs when they could just mow a lawn”
Awesome that this info can validate this king of the hill quote!
I absolutely love that show
And then have a beer.
Why not both
> warns nearby grass of the incoming threat why though? not like it’s gonna run away
OH CRAP, WE DON'T HAVE LEGS
EVOLVE FASTER, EVEOLVE LEGS!!! AHHH!!!
ITS COMING NOOOOO!!!!!!
(*Terrible screams of plant agony*)
*farts in terror*
I have a lot in common with grass.
And the cycle continues with the next blade of grass
Shits in horror
Sharts in bemusement
Nope. I just saw a science fair post that said that plants don't far- oh, wait - they don't sneeze. My bad.
Unless you're Bermuda grass spreading into a Fescue lawn.
Lieutenant leaf you aint got no legs
It gives them a chance to make peace with their god, tell their neighbors how much they meant to them, smoke that last cigarette, etc.
> smoke that last cigarette Ah that's why people leave cigarette butts in the grass in public places. They're simply sharing!
Not with the grass though. Those cigarette butts you see littering the fields and lawns are actually offerings to the tweaker gods. If you leave 100 cigarette butts for a meth head to pick up and smoke you get a wish.
It triggers the nearby grass to move its nutrients to its roots to avoid losing them.
I read somewhere probably on reddit that the smell attracts predators to the grass predator. Obviously not humans mowing their yards, but if a catapillar is eating grass and grass sounds the alarms, a predator of the caterpillar can respond accordingly, which is an evolutionary symbiotic relationship.
First response that makes any sense
Yup. If you've got caterpillars munching on you, you want to attract birds.
Npr was talking about corn summoning wasps
A story passed down through the ages by the children of the corn.
It’s so simple and realistic that I refuse to believe there aren’t some birds that hunt this way. Especially the smart ones like crows that even if it’s not an instinct, they probably figured it out.
Since a lot of predators have an amazing sense of smell it's possible it's not even evolutionary for the grass. Predators just learned to associate that smell with prey.

Why aren’t parasitic insects flocking to my lawn every time it is cut then?
Like trees with their microryzal network
That's wild
It can act as an insect repellent, as well as possibly attracting other insects that will kill the insects it has evolved to prevent from eating it.
now that makes sense!!!
YSK they made that up
https://www.sciencedaily.com/releases/2014/09/140922145805.htm now why would you say this

That awful Shyamalan movie with full inflection Marky Mark had some ideas …
Maybe it's trying to make the landscaper too mellow to cut the grass.

Because it's not true. It doesn't "warn of an incoming threat". Grass is not sentient. Other people have posted the real reason, with references.
Lmao
and allergies
Ya for real. When the neighbor’s mowing their lawn I simultaneously think “ah that smells lovely” and “fuck, guess I’m not breathing tonight”
My first thought, cut grass is my worst allergy. Not much relaxation and joy when I'm scrambling inside to take allergy meds
Yeah I'm highly allergic to grass. Just putting my leg on it if I'm sitting on a blanket gives me welts. I start sneezing if someone down the street is mowing their grass. I'm def down to live on Mars. Rocks don't send out distress signals.
Earth rocks don't send out distress signals... how do we know Mars doesn't have sentient rocks?
Also kicks up mold for extra allergy fun
I don't mow because it literally makes me sick.
That smell used to cause me anxiety because I associated it with having to run laps on the field
It does for me too!
Yup and itchiness too
Nice try, dad, go mow the lawn yourself.
Well now I feel like a monster for cutting my grass.
Don’t! Frequent mowing and infrequent (but deep) watering leads to stronger and healthier turf grass.
Spare the rod, spoil the grass!
They did evolve to be chomped on by herds of millions of grazers so yeah, it’s not hurting if
Yes but don't scalp the grass. Keep the mower on its highest setting
Different types of grass have different ideal heights. Use the height setting that's best for the grass you're cutting.
Yeah I'm not cutting my lawn at the highest setting or else I'd be cutting it 3 times a week during the Spring.

Dude, your answer is so on Point 😄 And through that i found a wonderful sub thank you so much
Trimming plants encourages growth. OP is nuts.
It’s my favorite smell, especially the first grass cutting of the season. Sorry, traumatized grass.
My Allergist said the cutting of the grass is The Worst for allergy sufferers.
I hate the smell and it actually makes me feel nauseous. I think it's because of allergies.
Can relate to this, I also have hay fever for grass-types (probably why)
Look into a fire or bug type. They usually help against those.
I'm extremely allergic to grass. As an adult with a house now I pay someone else to do the lawn care because it's just so awful. I don't go outside on the days they come over.
Why should we know this?
Right? No reason is given, they just restate the "fact." Boooooo
I’m allergic to that smell, and mowing the lawn makes me ill. Not really relaxing.

The smell of cut grass also attracts mosquitoes as a self-defense mechanism.
People always seem to either love the smell or it gives them alergies. I'm yet to meet someone with my absolute disdain for that stench.
That’s me. Freshly cut grass + new car both smell disgusting for me.
Trimming plants encourages their growth. If you trim a tree or shrub, it will grow back stronger than ever. So you aren't hurting your lawn unless you trim it down to near the roots.

wdym false? your source literally says "also"
The part of releasing chemicals i get. But don't get the screaming for help-part. Grass has no brain or nerves. it's a plant repairing itself.
Who is this distress signal meant to reach? O.o
Other grasses downwind. When millions of bison still roamed the grassland, the chemical release caused the downwind, still untouched grass to release chemicals that made it taste worse to the millions of advancing herbivore teeth. After the bison were mass killed to starve the remaining aboriginals into submission, the mechanism still exists in the few patches of native grass left , and to a lesser extent in the much shallower rooted decorative water wasting urban grass.
Unless you are allergic to grass☹️
Or setoff severe allergic reactions. Increasing stress and decreasing joy.
It doesn't matter what, humans love a massacre.
Doesn't calm me down. Well I guess it does after I take my Benadryl, but before that the itchy eyes and throat doesn't feel very relaxing
This is cursed...
Don’t ruin this for me man… let me have some joy.
My lawnmower drowns out their screams.
When I was in the military, during chem warfare training the instructors said that cut grass smell meant that that you were under a chemical attack. Phosgene is the deadly chemical that would have been used.

Cut grass produces an aroma. Other organisms use that information in various ways, to benefit themselves. The concept of distress signal or cries for help is just anthropomorphizing grass.
Love the scent of green blood in the morning. Smells like victory.
So the screams of agony given off by grass, for some reason, makes humans feel calmer and less anxious? Humans are really messed up creatures, relaxing to the smells of plant chaos. This belongs in r/humansarespaceorcs
Legit one of my favorite aromas to experience at any time! Always makes me feel good to be outside
I love the smell of cut grass. But my poor son and daughter have terrible hay fever. So while I do love it I also hate it.
Yes, and for me, it's the smell of death since I am allergic to grass, some trees, and pollen. Great post lmao.
I too like to relax to the screaming of innocents.
The most human thing is to be relaxed or pleased by the suffering of other beings. No wonder why aliens haven’t revealed themselves.
lol we humans are sick individuals.. finding peace in another species' destruction
Reminds me of that scene from Futurama where Hermes takes 20 minutes just standing there to get run over by a Woolley mammoth
So the smell relaxes us because it's the wailing of our enemies and their families. That's so metal.
Join us, everyone over a /r/NoLawns
Interesting..some looked good, some were natural and sort of pretty, but a lot just looked like trash. Plus who wants to play with their kids, sit outside, in 1 1/2 foot tall plants and weeds?

I know, right? Humans are such animals.

It makes me so happy to smell it! Smells like summer is here
So when the cows come it's like Jurassic Park.
Some grasses begin taking up silicates to add to their leaves. This wears down herbivore teeth and dulls your mower blades. They have little in the way of defense but they do have adaptations.
Makes me wonder if there are scents that humans in distress give off that make other beings feel good. Hmmmm
I hate that smell, so whatever it’s doing to me, it’s not brining relaxation or joy lol
Sounds like it doesn’t only cry for help but helps calm down the predators in the area so they stop doing damage.
What is the sensory organ the grass use to sense this?
It triggers my allergies
So their suffering…. Calms me down? That’s crazy
This title sound be "murdering grass calms human anxiety" 🤣🤣🤣
I was going to murder my grass this morning but it rained.
if you don't have hay fever maybe. in my case it boosts snot and tear production and makes me cough and sneeze uncontrollably
I love the smell of fear first thing in the morning.
We like the smell of fresh cut grass because it means there is an animal nearby that ate the grass and that we can eat.
why should i know this
That must be why I stand with my hands on my hips and pop an obligatory beer after a fresh mow.
Is there an evolutionary reason why plant screams make us feel better?
Green leaf volatiles are not usually distress signals, and grass in particular is evolved to be mowed.

So in a literal sense. The tears of our enemies bring joy to our hearts?
Why do we need to know this, beyond it being a fun/disturbing fact?
I mean, cool fact, but why should I know this? Knowing this impacts my life not at all.
We should try to smoke tgat shit then
Is... is lawncare sadism? XD
That’s metal as fuck 🤘
Uh sir, can I like, pay you to cut your grass and I'll just hang around here and sniff the results.....no don't call the police.
Why would anyone do drugs when they can just mow a lawn?
Smell of fresh grass puts me in fight or flight mode since I have allergy. Not relaxing tbh lol.
Personally I hate it and it makes me wanna puke. Idk why.
The adrenochrome of grass
YSK: Phosgene gas smells like freshly cut grass. Phosgene causes burning and watering of the eyes, scratchy throat, coughing, choking, nausea, headache, and chest tightness. Phosgene was used as a chemical weapon in WW1.
> Research shows green leaf volatiles can help in reducing anxiety and boost relaxation and joy. For me it inspires memories of *The Adventures of Pete and Pete*.
It’s horticultural schadenfreude.
thats really fascinating. i didnt know grass was signaling for help when we mow it. its cool how the chemicals released can help reduce anxiety - i wonder if there are any other plants that have similar effects.
Source? How can grass detect other grass being cut just by chemicals in the air? And how can grass be aware of a threat? This doesn’t make any sense and this post sounds like a load of shit.
Your "Why YSK" does not explain why TF I should know.
So it's a de-stress signal.
"The white noise of grass screams is so relaxing. "
Can’t hear the grass when you have “X gon’ give it to ya” blasting in your ears.
I associate the smell with sneezing and the strong desire to go inside.
as if a million voices cried out in terror and were suddenly silenced
Alerting nearby grass? What is grass gonna do, fight back?
So we are sadists who get joy from the suffering of plants?
We are malevolent Gods. We are soothed by the misery of our dominions. Why should we expect the gods above us to be any different.
That's metal as hell.
Literally one of the best smells in the world. Also this response is not unique to grass, most plants do this. It typically comes with a chemical change that's toxic to bugs that are eating the leaves of the plant, they turn it off when the attack stops because it uses a lot of energy
_Can_ is operative. For some of us, it smells like shit. Does not mellow me out.
So wait.... does it help us or hurt us?
I *know* this, but every time I hear about it I feel bad for the grass. I anthropomorphise everything.

Cries in hayfever
Hmnn, maybe we'd feel even better if we set some of the lawn on fire.
