We hear advice to practice tabular array salt as a mourning band killer and see it urge in recipes for diy weed treatments . But it ’s not that simple . Even though Strategic Arms Limitation Talks is “ natural , ” it is not harmless . surplus Strategic Arms Limitation Talks get tremendous damage to nature and our ecosystem .
This is part of series where we explorepopular garden myth we have all fallen forand fact - check common garden advice .
Is Table Salt Good for the Garden?
Use of table salt in the garden is not recommended because it can not target specific green goddess and can do other trauma . Salt is soluble , gets in the soil and water , and , cumulatively , causes damage to the ecosystem . At eminent levels , it ’s toxic to plants , aquatic flora , and wildlife .
It seems like just about anything we line up in our kitchen has been annunciate as great for our garden — as weedkiller , pesticide , fertilizer , or other uses .
There is this longstanding estimate that because we use something daily in our home plate — and , like salinity , is get in nature — that it must be good or harmless in the garden .
But this is not so .
salinity ( sodium chloride ) is indeed natural but , when levels are overweening , it causes marvelous impairment to dirt and water .
You might think , what ’s the harm if I practice a footling in my garden to try out and kill somedandelions ? Ca n’t I just spray some on my drive or terrace ?
But the fact is , these diy mourning band killer remedy are partake in by billion of gardeners — and that ’s a lot of Strategic Arms Limitation Talks ( and other essence like dish soap ) being inaugurate into nature where it does not belong .
at long last , as gardeners and stewards of the earth , we require our choices to benefit the ecosystem as a whole .
So , when thinking about using salt or anything else , these are helpful doubtfulness to ask first :
Because , if you ’re like me and you desire to garden with nature and the environment , not against it , there ’s no such matter as choices made in isolation .
Treating one problem only to cause another is not really a good solution at all .
Yes , table salt may toss off sess , but also does greater harm .

Table Salt in the Garden
Toxic Effects of Salt
One of the most popular recipes online for homemade weed cause of death calls for some compounding of vinegar , dish max , and table salt ( sodium chloride ) orEpsom salt(magnesium sulphate ) .
We ’ve already discussedthe effects of acetum in the garden hereandwhat dish easy lay does to plants here , which ramble from useless to harmful reckon on the app .
If you ’ve read story , at first coup d’oeil , mesa salt seems like an unbelievable candidate for gardening . There are chronicle locomote back thousands of years of salt being used in a vindictive way to destroy agrarian state .
In addition to Biblical stories , you may have heard of the Romans salting the farming area of Carthage . That ’s more folklore than chronicle , manifestly , but we ’ve long known about the toxic effect of salt .
Today , we are look at with the side effects of mod - day lotion .
Because salt lowers the freezing compass point of body of water , it has been used for many year to de - ice wintertime roads .
But now , knowing the environmental wrong caused as it gets into our fresh waterways , many community are seeking option .
And all of that connects to why it ’s questionable for home garden use as well .
touch on : The Problem With Vinegar as a Weed Killer
How Sodium Affects the Environment
Table Salt
The table salt we ’re talk about is table salt . Sodium chloride ( NaCl ) . The stuff in your salt shakers and in pocketbook of Strategic Arms Limitation Talks at the grocery store .
While not part of this discussion , Epsom common salt — not the same as table salt — is not a dependable solution in the garden either .
So , there ’s no question that saltiness kills works including weeds . In fact , it is not selective so it will affect whatever it touch — dope or not .
The more important level is whether it ’s something that we should be pouring or spraying in our gardens and , in the end , into our soil and waterway .
Because it ’s a kitchen product that we put on our food , there ’s a perceptual experience that it ’s environmentally friendly .
It ’s 100 % natural and lets you avoid putting harmful chemicals in your garden — they say !
If you suggested pouring acetic acid and Na chloride into gardens , you ’d get electric resistance , but “ vinegar ” and “ table salt ” sound much more innocent .
But salt is n’t harmless — peculiarly the sodium ion you ’d be free into your ground .
And , of course , there ’s no such affair as a harmless herbicide — it is killing something , after all — but some are more harmful than others .
Sodium is Toxic to Most Plants
Sodium is a toxic metal . Very toxic to most plants . And , while vinegar will melt ( but can get other issues ) , the atomic number 11 stay around — but not needs where you put it . It can get washed into any other part of your garden , and on to puddles , streams , rivers , and other waterways .
While a humble amount of salt is n’t going to ruin your garden or the environs , if you ’re using enough to kill your weeds , that total up .
And then multiply that by one thousand thousand of nurseryman around the world , and it ’s hard to urge common salt as environmentally - well-disposed or harmless .
So , can salts down weeds ? Yes .
Are there negatively charged side effects ? Yes .
Would I use it in my garden ? Nope .
The Role of Other Salts In The Garden
As a gardener , it ’s helpful to understand the conflict between table salt ( sodium chloride ) and other common salt .
Saltortable saltis sodium chloride . Salt is not a plant food .
chemic saltsare soluble ions or nutrient including ammonium ion , Ca , chloride , magnesium , nitrate , K , and sulfate that plant life demand to grow .
Chemists Define “Salt”
The Holy Writ “ table salt ” has been in the English spoken communication for centuries and it ’s one we all know and apply .
But , in the late 18th century , pill pusher occur up with a new , more scientifically precise definition of salt . And with that raw definition , what we know as salt — the stuff from saltiness shakers , also recognise as table common salt ( sodium chloride)—was just one ofhundreds of salts .
And this has been causing confusion ever since . When someone is talking about salt , do they meantable saltorchemical saltsin full general ?
It can be a particular trouble in gardening , because one of those salts is definitely bad for the garden and can vote out plants , while the other includes thing that can help plants , as long as they ’re used properly .
The Importance of Ions
Chemically , salts are a combination of two or more ion , which are molecule or mote with an electric charge , either positive or negatively charged . When they amount together in a common salt , those charge delete each other out and the common salt has no final electrical charge .
Almost all of thenutrients that plants take up from the soilare in the manikin ofions . We call them by their elementary name , but what flora in reality take up are those elements in ion .
So , for example , we blab about plants getting nitrogen from the soil , but what they actually take up are nitrate — a negatively consign ion — or ammonium — a positively charged ion .
associate to this , the pH grade of soil — a measure of the concentration of positively - shoot down hydrogen ions in the soil — changes how or if plants can take up nutrient ion .
Salt Examples
mesa salt(sodium chloride ) is a positively charged sodium ion and a negatively charged chloride ion , so it follow the same design .
Epsom saltis a shape of atomic number 12 sulphate ( MgSO4·7H2O ) , combining a positively charged magnesium ion and a negatively charged sulfate ion . And both atomic number 12 and sulphur are essential macronutrients for plant life .
Neither of these are suitable for treating sens in the garden because each one can cause other environmental issues . It is best to avoid any DIY green goddess killer recipes made from household products because they are not targeted and bring in substances into grunge and waterways that cause harmful imbalance affecting plant life and fauna .
Ions In Soil
Chemically , salt are represent of ion , and most of our plants ’ nutrients are ion . We want those ions in our soil .
Most of them are already there in sufficient amount ( there ’s very fiddling opportunity that your filth has a sulfur inadequacy , for example ) , but if asoil testconfirms that we need to add some works - approachable nutrients to the soil , a quick mode to do so is in the form of Strategic Arms Limitation Talks that will almost immediately dissolve into their ions once they reach moist grunge . That ’s whatsynthetic fertilizersdo . They are usually comprise of chemical salts that quickly become ions in the land .
But not all ion are nutrients — atomic number 11 , for representative , is not only not a nutrient but it canharm plant . And even nutrient ions can become a job if there’stoo muchof them — especially if there ’s too much of some of them and they get in they way of others that plants call for too .
So , when it come to your garden , you ca n’t generalize from table salt ( atomic number 11 chloride ) to all common salt . Sodium is bad for plants but most other salts do n’t include atomic number 11 and some are represent of nutrients that your soil need for your plants to be healthy .
What should I use instead?
remove weeds — which are unwanted plants — is both an art and science .
While certain invasive species can be very difficult to remove or eradicate , it is helpful to larn about the plant you are tackling to empathise how and when it reproduces or spread . That ’s key data for knowing the expert way to stop it .
These deweeding lead for home gardener should help .
There are no staring answers or solutions but at minimum it ’s rewarding to make choices that avoid causing environmental trauma .
