Given that plants do not have
Plants do not suffer in silence. Instead, when thirsty or stressed, plants make “airborne sounds”, according to a study published today in Cell1. Plants that need water or have recently had their stems cut produce up to roughly 35 sounds per hour, the authors found.
It's not quite clear yet how the plants make these sounds, but the scientists suspect it is a passive process linked to cavitation. This is when plants that are stressed pop air bubbles in their circulation system causing vibrations in the plant.
Does grass scream when you cut it? Oddly enough, it does! Scientists have discovered that grass elicits a high-pitched noise once cut. It is so high-pitched that humans cannot register the noise.
Plants can sense a lot about their environment and it can cause them stress. Unlike most humans and animals though, when plants face predation, damage, or environmental changes they can't run away and hide. Sessile – or stalkless – plants evolved to be incredibly sensitive to their environment in order to survive.
If something hurts humans, we react instinctually to it—“fight or flight”—as do other animals. But plants don't have that ability—nor do they have nervous systems or brains—so they may have no biological need to feel pain.
Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry.
They conducted all sorts of experiments with plants – playing music, talking to plants, vibrations, etc. But their findings were discredited. Now fast forward nearly 50 years, and it has never been scientifically proven that plants have feelings.
Grass allergies can present in a variety of ways, including nasal symptoms (runny nose, stuffiness, sneezing), asthma, and eye symptoms (itchy, watery/red eyes). People can also have skin rashes (hives or skin welts) after exposure to grasses, but this is much less common.
Short answer: no. Plants have no brain or central nervous system, which means they can't feel anything.
In fact, it makes perfect sense. Especially if you've been calling yourself a "plant mom." Acquiring a new houseplant is an act of optimism.
Make Your Cuts
Make judicious cuts to encourage new growth. Cut just before a leaf node. Or when cutting back larger stems, cut as close to the main stem as possible. However, do not remove more than 25 percent of the plant.
Plants can sense and react to more aspects of their environments than we can, and they maintain bustling social lives by communicating with each other above and below ground. They also interact with other species.
Nor does it experience fear, anger, relief or sadness as it topples to the ground. Trees — and all plants, for that matter — feel nothing at all, because consciousness, emotions and cognition are hallmarks of animals alone, scientists recently reported in an opinion article.
Do Plants Have Feelings (Or Emotions)? No – unlike humans and non-human animals, plants do not have feelings. It is undeniable that a plant can respond to environmental stimuli, like turning towards the light or closing over a fly. But that doesn't prove that they can have feelings, such as pain.
Shower immediately after mowing to remove pollen and shorten the duration of your allergy symptoms. Keep your yard as pollen-free as possible by planting only female trees and shrubs.
No, walking on grass doesn't kill it...
Think of those thin green blades as leaves: yes, they serve an important purpose, but the grass plant can survive and continue to grow even if its blades are damaged (whether by a lawn mower, a grazing animal, or your favourite pair of shoes).
Grass being allowed to grow too long can result in the grass slowly suffocating itself, shading its own roots and soil from sunlight and other sources of essential nutrients. In a general sense, overly-long grass is a lot less healthy than regularly maintained grass.
Your plants really dislike when you touch them, apparently. A new study out of the La Trobe Institute for Agriculture and Food has found that most plants are extremely sensitive to touch, and even a light touch can significantly stunt their growth, reports Phys.org.
Even so, there are compelling reasons that chatting up your potted pals is good for them — and you. Plants don't interrupt when you're speaking. They don't argue or ask difficult questions. And regardless of whether they're actually listening, research has shown them to be a calming presence.
“But some research shows that speaking nicely to plants will support their growth, whereas yelling at them won't. Rather than the meaning of words, however, this may have more to do with vibrations and volume. Plants react favourably to low levels of vibrations, around 115-250hz being ideal.”
Known colloquially as the gympie gympie (from the Gubbi Gubbi/ Kabi Kabi name for the plant, gimpi gimpi), gympie stinger, and giant stinging tree (D. excelsa), this plant has the dubious honour of being arguably the most painful plant in the world.
Plants thrive when they listen to music that sits between 115Hz and 250Hz, as the vibrations emitted by such music emulate similar sounds in nature. Plants don't like being exposed to music more than one to three hours per day. Jazz and classical music seems to be the music of choice for ultimate plant stimulation.
Although plants do not sleep in the same way that humans do, they do have more and less active times and they have circadian rhythms—internal clocks that tell them when it is night and when it is day. And like many people, plants are less active at night. When the Sun comes up, however, they awake to the day.
