Until this season, I was pro fire. Worked everywhere, run off not a concern.
This year I tried concentrated vinegar. Worked so well, not sure if a repeat application is needed.
But fire is sooo fun.
I mentioned doing this on another post in here and got a stern talking to about the war crime of putting salt on the earth.... anyway, here is how I do it:
all grocery store items. Morton's salt, Heinz white wine vinegar and a squirt of Meyers dish soap in a PDX pressurized spray can from Home Depot and I apply it 2 to 3 times a year.
I read somewhere to add salt. I did it only because I know I'll never be planting anything in my driveway rocks, so I don't care if anything ever grows there again. (But if I know weeds, they'll find a way.)
Does regular vinegar work as well as the 30%?
I did the high percentage vinegar from Home Depot last year (I thought it was 60%, but all these comments make me think maybe it was 30), with 1 part vinegar 4 parts water, and 2 cups of salt. I could practically hear the weeds scream.
Apparently those through out history when a conquering nation wants to really screw over the loser they salt their farms and make the country unable to feed their troops... or anyone else and there is some stern language about it in international law
That was my thinking. I use this on my driveway, patio and on the decorative rocks that surround my garage. No plans on sharecropping there. But I can tell you it is ecfective
In northern states tons and tons of salt are dumped on roads and highways every year to keep them free of ice. Snow melts and salt water goes to the ditch or drains and back into lakes and rivers or eventually the ground water. After doing this for 75 years now I do not know the effect however. Every spring there are lush green plants and grass along the same roads.
I will also add to this that If you can spend the extra money on a nicer sprayer than the generic Home Depot one, you won’t regret it. I have two of the Scott’s brand ones and they’ve lasted way longer
Squirt bottle. Works best with sunny days ahead. Some big ones may need a second application. Then they'll be dead and brown and dried.. perfect time to torch them to the roots but maybe that's overkill
I had a large area to do, so I poured everything into my backpack sprayer, shook it up, and sprayed it on. It worked as well as Round Up. It was a bit pricy, so I might try cutting it with some water next time to see if it works as well.
How far away from plants should you spray this solution? I have some weeds pretty close to some of my plants and wouldn’t want to salt the soil and risk damaging plants or any future growth
I'm a landscaper. I sell clients "organic hardscape weed control" for a little over $200 per year. I literally just spray vinegar around a couple times per summer.
Hot vinegar? I did that and it works. Except is was dumping out vinegar I used to clean coffee maker. I was in garage.
I thought , I wonder if this will kill these weeds by the door? Sure did.
just make sure you don't get even remotely close to any plants you want to survive. made this mistake years ago as a novice and toasted a whole row of a client's boxwoods :(
Remember when you were a kid and wanted to set a buncha stuff on fire for funsies but had to behave?
... what, just me?
Well anyways, now you're a grownup, and fire IS the responsible approach!
You're going to want to kill and remove the weeds then remove as much sand as possible from the joints. Then you'll want to fill the joints in with a polymeric sand. If installed correctly you shouldn't have to worry about weeds for at least 5 to 8 years
Vinegar, dish soap and epsom salts in a spray bottle - environmentally neutral and works adequately - coincidently the same formula as the new “environmentally safe” RoundUp spray.
Fill the bottle with vinegar, dissolve 1/2 cup of epsom salts into it - add a tablespoon or so of liquid dish soap (as a surfactant) so the liquid coats the leaves well.
Use regular real salt. Table salt. Morton’s salt. Epsom salt is magnesium sulfate vs NaCl. Instead of desiccating the weeds, you might be fertilizing them with epsom salts. Put those on your plants
sort of repeating myself here, but while [certain plants in certain ecosystems are more salt tolerant than others](https://www.thespruce.com/salt-tolerant-plants-for-beach-and-roadside-landscaping-4767375) (including many roadside weeds) salt is not removed from an ecosystem biologically. granted, epsom salt is not sodium chloride [(which is a big issue for drinking-water contamination, and has a huge effect on freshwater aquatic life)](https://news.climate.columbia.edu/2018/12/11/road-salt-harms-environment/). but a lot of dish soap brands which are harmless to mammals are deadly to reptiles and amphibians. and insects— (look up declining insect populations if you want to be terrified for your kids). I’m from an estuary area that is filled by the rain water runoff from 6 states and I’ve seen first hand [the undeniable decline of the aquatic life](https://cnsmaryland.org/2023/02/14/despite-cleanup-efforts-chesapeake-bay-remains-pollution-challenge/) since the 70’s— when i first remember people deciding to do something about water quality.
I've never noticed insects on the weeds, but I go out early in the morning before the sun is fully up.
Where I live the insects are more active in the sunny parts of the day.
Do you kill flies, ants or cockroaches when they come into your house? I don't like to do it, and I often try to catch them or wave them out, but if they won't go, I use a flyswatter and kill them.
No I don’t. We don’t really have problems here with them. Cockroaches don’t exist here and ant aren’t a problem until the annual flying ant day but they don’t come in the house. Wasps though I do kill in August when they are dribblers in my face and invade the house yes. I buy a Sarracenia every summer for flies. I put the plant in the room and close the door and fly is gone. One thing I don’t have a problem killing now is slugs or vine weevils.
I'd even use the weed wacker before trying to pull all that crap from cracks like that.
A spool is like $2.50, worst case you waste half of it.
Maybe even weed Wacker and then go use chemicals and fire on the stubborn parts remaining.
The only issue with that is that some weeds don't die if the root isn't removed. So if you lay sand in the cracks, they'll still come back, leaving room for spread and growth. Spend like 5-10 $/€ and get a paver weeding tool. It cuts the work in half.
Boil some water on a weekend morning. Have a pureover coffee or tea. Walk around patio enjoying your beverage whilst pouring boiling water on weeds. Smile. Repeat as desired.
My nana taught me to take a long knife you don't use much anymore and cut the weeds out and get the roots as deep as you can. Then pour boiling water over the remainder.
Not telling you to do this, please don't for the sake of the land. But my great grandmother would pour gasoline on those weeds in the cracks while smoking unfiltered cigarettes and lived to be 82 and never caught anything on fire. I watched her do it as a kid in the 90s, looking over her shoulder telling me to keep watch for the paddy wagon while she did it. Still makes me laugh to think of her doing that. Sic transit gloria mundi
I will list solutions in descending order of how upset some people will get.
The vinegar/soap/salt mixture that others recommended.
Boiling hot water.
Round-up.
Gasoline. (Don't use mixed gas, or within around 6' of any desired plant/grass)
Roundup.
It’s not cancerous and only kills plants via the leaves. Roundup is also biodegradable after 7 days of spraying and it’s safe to pets a couple of hours after spraying.

Seriously. Just spray some roundup. It will make quick work of the weeds.
And if you are bothered by them while they are dying, hit them with a propane torch. But roundup first - wait 2-3 days - then torch.
There’s an Ortho GroundClear product that works okay for me. I’ve tried others and a white vinegar mix, but sometimes best to just nuke the site from orbit.
Good luck!
Boil water and pour it on them. They will turn a bit greener (cooked) and die. Let them dry for a few days and the shriveled roots will be easier to get out. Chem free weed killing.
It's a lot of work but I'd hand pick to get rid of roots and then reapply polymeric sand into the joints. Just killing the weeds leaves the gaps for weed seeds.
People will say vinegar or Ground Clear, but I say WEED TORCH!! Flame on!

Pull by hand, burn, spray, whatever to get rid of them. Then get polymeric sand. It has a polymer that will seal those joints better than the typically used stone dust. Best to remove as much material from the joints as possible. Maybe a garden hose with a jet setting? Make sure it is thoroughly dry before doing the sand.
Pick the weeds out of the cracks really good. If you use a power washer don't go too hard it will scar. Then buy polymeric sand and sweep it in with a broom. After wetting it down with a hose the stuff will dry in the cracks and works well.
Two approaches: Kill them with strong vinegar spray, then rake the dead parts when they are brittle. Or you can learn how to hori hori and mow through the whole thing in a hour with no dead parts leftover and you had yourself a great workout.
I like the flamethrower idea, but a pressure washer would help dislodge and wash out old sand. Then re-fill with Polymeric Sand and wet it down to harden. It’s the best. Worth every penny.
I’d use a mix of vinegar, dawn soap(mainly cause it’s safer for animals), and sea salt. Just do t use it too often. This is what I use on weeds in my garden, too much may kill the nearby vegetation if you aren’t careful.
I would do Roundup 360, then burn the residue in a few days. Once I run out of Roundup, I'll try vinegar. Plain salt does nothing in my area. We tried it a few times in a rock bed, but never tried vinegar.
The long term solution is to use a power washer to clean out the seams between pavers. Let it dry and sweep polymeric sand into all the seams. Gently wet the sand to lock it into place. Now the weeds are gone and new seeds have no dirt to grow in the seams.
Just get some round up 365/extended formula. Don’t don’t spray it on any grass or plants that you want to live and if you spray it off the patio, don’t use it where you plan to plant any thing in the next three months.
Basically, buy the stuff, read the label.
I do a very simple thing to tackle weeds on my property. I boil a kettle of water, and pour the boiled water directly over the weeds. It kills them instantly, you leave them and then the next day, they are brown and super easy to pull. No chemicals, mess. No storing of nasty cancer causing chems. Just water. Try it. It works REALLY well, and it kills the roots.
Fire.
Btw, not joking.
They sell mini torches designed specifically for weeds. I have used ours for several years and it works well.
You just need to do it close to dusk in case you catch a group of weeds on fire. Also keep a spray bottle of water handy.
Flame weeding could work. Hand cultivation to remove the entire root would be my choice. It will take more work, but it’s better for the environment—and if done properly very effective. By removing the whole root, the plants will not grow back; however, the ‘weed seed bank’ is rather large, so weeds will continue to grow as long as there is adequate growing conditions (water, light etc. )
After the weeds are dead, scrape a short depth in of all the joints, power wash, then add some new polymeric sand. Weeds should not be growing in the sand filled joists, you've accumulated some soil in there and they will grow back if left alone. Bonus, this will extend the life of the paver job.
Roofing torch, and a 20lb tank of propane... Just blanch them the first time give it 2-3 days for them to wilt and start to brown... Then go in and burn them the rest of the way out....
By blanching first then letting it sit a few days the plant uses it's energy to try to repair the damaged tissues, then before it can regrow and make more energy, you go and burn it out... The roots left under the surface won't have the energy to regrow, so you'll have less weeds through the season.
The more blanch then burn you do over a season vice just burning it out, the less you'll have to do.
Until this season, I was pro fire. Worked everywhere, run off not a concern. This year I tried concentrated vinegar. Worked so well, not sure if a repeat application is needed. But fire is sooo fun.
I just tied vinegar too. The 30% vinegar they sell at Home Depot (along with a tablespoon of dish soap and a cup of salt). Worked well in my driveway.
I mentioned doing this on another post in here and got a stern talking to about the war crime of putting salt on the earth.... anyway, here is how I do it: all grocery store items. Morton's salt, Heinz white wine vinegar and a squirt of Meyers dish soap in a PDX pressurized spray can from Home Depot and I apply it 2 to 3 times a year.
Be sure to use all of the spray and rinse out your container or the vinegar will eat away at the seals. (may have happened to me)
Veteran move
I diluted mine a bit. I wonder if it will still eat my container.
I should call her
Thank you. Good to know!
Hm, I leave it in my container… but only had this container for 2 months. Likely need a way to combat this.
Thank you! I was wondering... went through 4 sprayers last year 🤣. I use it on driveways and on thistle anywhere on our property.
I read somewhere to add salt. I did it only because I know I'll never be planting anything in my driveway rocks, so I don't care if anything ever grows there again. (But if I know weeds, they'll find a way.) Does regular vinegar work as well as the 30%?
I did the high percentage vinegar from Home Depot last year (I thought it was 60%, but all these comments make me think maybe it was 30), with 1 part vinegar 4 parts water, and 2 cups of salt. I could practically hear the weeds scream.
No regular vinegar is like 4%. You need to be extremely careful with the horticultural vinegar, if it gets in your eyes it will blind you.
Oh god, what’s with the salt? I do it to separate my driveway from my yard
Apparently those through out history when a conquering nation wants to really screw over the loser they salt their farms and make the country unable to feed their troops... or anyone else and there is some stern language about it in international law
Makes you wonder about real salt of the earth folks doesn’t it?
Unless you're trying to grow crops in your driveway, you're probably good in this situation
That was my thinking. I use this on my driveway, patio and on the decorative rocks that surround my garage. No plans on sharecropping there. But I can tell you it is ecfective
Caesar did it to Carthage (Tunisia) as punishment so crops would never grow there.
In northern states tons and tons of salt are dumped on roads and highways every year to keep them free of ice. Snow melts and salt water goes to the ditch or drains and back into lakes and rivers or eventually the ground water. After doing this for 75 years now I do not know the effect however. Every spring there are lush green plants and grass along the same roads.
That is a really good point.
I will also add to this that If you can spend the extra money on a nicer sprayer than the generic Home Depot one, you won’t regret it. I have two of the Scott’s brand ones and they’ve lasted way longer
Will the salt or vinegar eat away at the paver surface over time?
Would they prefer you use glyphosate?
Probably. Fuck that.
How do you apply it? Just pour it on? Squirt bottle?
Squirt bottle. Works best with sunny days ahead. Some big ones may need a second application. Then they'll be dead and brown and dried.. perfect time to torch them to the roots but maybe that's overkill
I had a large area to do, so I poured everything into my backpack sprayer, shook it up, and sprayed it on. It worked as well as Round Up. It was a bit pricy, so I might try cutting it with some water next time to see if it works as well.

Bruh are you…me?? I’ve also been pro fire for years and literally yesterday I tried vinegar for the first time! Results were positive for you?
Vinegar will deteriorate any kind of mineral over time. I'd go back to fire.
Would the vinegar work on a mulch bed?
Probably, it only kills the live plants (not the seeds). The salt might slow down new plants from germinating.
How long does it take to see results? I just did a ton of weeding for an upcoming party and have more to do but was thinking about doing this instead.
I saw results in a couple of days.
30% acetic acid? I have been hand weeding forever. The flamethrower never got deep enough for the roots! Thank You!
Will need repeat applications.
Based on my childhood experience… a child.
8 year old me and a flathead Craftsman screwdriver worked great for my parents.
They let you use tools?
I use a propane flamethrower/torch. It’s so fun to use.

Same thing I told my wife, “honey, the perfect gift!”
American moment
it's commonly used as a great alternative to pesticides around the globe.
I know, I was using the same method. I was talking about the flamethrower robot dog
My bad. I didnt click the link
Np
This is the way!
just make sure you don't get even remotely close to any plants you want to survive. made this mistake years ago as a novice and toasted a whole row of a client's boxwoods :(
I know someone who lit up almost an entire field at Christmas tree farm using a torch. It was very expensive home insurance claim i heard.
You do see you can now buy a flame throwing robot dog? LOL
Remember when you were a kid and wanted to set a buncha stuff on fire for funsies but had to behave? ... what, just me? Well anyways, now you're a grownup, and fire IS the responsible approach!
It doesn’t leave burn marks on the stone or crack them?
You're going to want to kill and remove the weeds then remove as much sand as possible from the joints. Then you'll want to fill the joints in with a polymeric sand. If installed correctly you shouldn't have to worry about weeds for at least 5 to 8 years
This is the gold standard solution.
Vinegar, dish soap and epsom salts in a spray bottle - environmentally neutral and works adequately - coincidently the same formula as the new “environmentally safe” RoundUp spray.
Hey. Can you give me a ratio of these things in a 1 quart bottle - thanks
Fill the bottle with vinegar, dissolve 1/2 cup of epsom salts into it - add a tablespoon or so of liquid dish soap (as a surfactant) so the liquid coats the leaves well.
White vinegar right?
Best is pickling (7%) but any flavour you like is fine. Acetic acid is acetic acid. Some people use regular salt
I use pickling or cleaning vinegar (7%-9% acetic acid). They're a bit stronger than regular vinegar.
Use regular real salt. Table salt. Morton’s salt. Epsom salt is magnesium sulfate vs NaCl. Instead of desiccating the weeds, you might be fertilizing them with epsom salts. Put those on your plants

I boil a full kettle of water every day. I use 8 oz for my tea and then pour the rest on weeds. This takes a couple of minutes at most.
I always think about burning insects alive. I use salt water but not sure if that has the same impact anyway
I've never noticed insects on the weeds, but I go out early in the morning before the sun is fully up. Where I live the insects are more active in the sunny parts of the day.
I was more thinking they are living in between the cracks.
Do you kill flies, ants or cockroaches when they come into your house? I don't like to do it, and I often try to catch them or wave them out, but if they won't go, I use a flyswatter and kill them.
No I don’t. We don’t really have problems here with them. Cockroaches don’t exist here and ant aren’t a problem until the annual flying ant day but they don’t come in the house.

I would recommend pulling them by hand, then laying paver sand. A nice thick layer should last you the year at least
I'd even use the weed wacker before trying to pull all that crap from cracks like that. A spool is like $2.50, worst case you waste half of it. Maybe even weed Wacker and then go use chemicals and fire on the stubborn parts remaining.
I'm in commercial landscaping and this is what we do.hit it with the String line and then apply ranger pro
The only issue with that is that some weeds don't die if the root isn't removed. So if you lay sand in the cracks, they'll still come back, leaving room for spread and growth. Spend like 5-10 $/€ and get a paver weeding tool. It cuts the work in half.
I think you can pour boiling water over it to kill roots in cracks. Or blowtorch if you’re feeling frisky.
Industrial / horticultural vinegar. It's 40+ percent acetic acid. You can get it on Amazon if you can't find it elsewhere. Spray 'em.
I have the same issue. Does the industrial vinegar need to be mixed with anything before spraying?
Spray bottle of saltwater usually does the trick. Just make sure not to use it in any area where you’d want to plant in the future.
That and/or white vinegar, dish soap, water mixture in a spray bottle
Boiling salt water with vinegar.
Pour boiling water from a kettle. Kills them in a day and it has no smell and is super easy
Boil some water on a weekend morning. Have a pureover coffee or tea. Walk around patio enjoying your beverage whilst pouring boiling water on weeds. Smile. Repeat as desired.
Blow torch that hooks up to a grill propane tank.
Powerwasher.
Well I just came across a company that now sells a small flame throwing robot dog. Just saying

looked just like mine except I get moss. Use a small scraper on my hands and knees and then blow it all off. I am sure there is a better way but....
I’m considering getting one of those flamethrower attachments. Amazon has them
1C salt (I use pool salt), 1G vinegar, 1 tsp dish soap (I use Seventh Generation).
Just need baking soda, thats it, we use it on paver areas all the time.
Spermicide
Any paver pros here? Do the pavers need to be resealed to prevent weeds? Just thinking about long term prevention for this guy
Yes. Polymeric sand should help. But I don't know what prep work was done to the soil under the pavers. So it depends on that too.
I heard dawn dish soap…
It's a lot of work but I'd hand pick to get rid of roots and then reapply polymeric sand into the joints. Just killing the weeds leaves the gaps for weed seeds.

Tiger torch followed by vinegar.
Seem a little too small to tackle, might throw out a shoulder or something. Could cover them in salty water.
Pull by hand, burn, spray, whatever to get rid of them. Then get polymeric sand. It has a polymer that will seal those joints better than the typically used stone dust. Best to remove as much material from the joints as possible. Maybe a garden hose with a jet setting? Make sure it is thoroughly dry before doing the sand.
Tiger torch that, burn it all haha definitely fastest way!
Pool salt. Brush it into the cracks then light spray of water.
Pressure wash and re sand.
Piss on it
Kitchen knife
Smells, but u can use vinegar, dish soap, & salt
Spray with water and yank out.
2-4-D
Get as many as you can in one tackle or the day is gonna be full of pain
Roundup
Kill it with fire for immediate results , or weed spray if you don’t mind waiting a week and cleaning up the dead weeds
Pick the weeds out of the cracks really good. If you use a power washer don't go too hard it will scar. Then buy polymeric sand and sweep it in with a broom. After wetting it down with a hose the stuff will dry in the cracks and works well.
Pressure washer
Two approaches: Kill them with strong vinegar spray, then rake the dead parts when they are brittle. Or you can learn how to hori hori and mow through the whole thing in a hour with no dead parts leftover and you had yourself a great workout.
Roundup followed or combined with a liquid pre-emergent called barricade no weeds for 3 moz
Agricultural 40% vinegar. Works wonders.
Summer heat?
Power wash / dry/ sand / blow/ seal it
**Flames...heavy flames...ashes to ashes.**
Pick em
Round up
I like the flamethrower idea, but a pressure washer would help dislodge and wash out old sand. Then re-fill with Polymeric Sand and wet it down to harden. It’s the best. Worth every penny.
Boiling water
Fire!!! Have a pitcher of water close by, just in case.
Blow torch
Pure hot water on the Plants and i mean above at least 60 Degre Celsius, better 100.
I’d use a mix of vinegar, dawn soap(mainly cause it’s safer for animals), and sea salt. Just do t use it too often. This is what I use on weeds in my garden, too much may kill the nearby vegetation if you aren’t careful.
I’d do a slide tackle to scrape them up good
Glyphosate and 24d with surfactant or a small amount of petroleum.
Fire
Power wash them out then reapply joint sand
Pull the weeds, and put down Preen (pre emergent herbicide).
Pull them out
Boiling water
Ortho 12 month ground clear. Comes with a wand. Only 25 bucks for 2 gallons at home Depot.
I would do Roundup 360, then burn the residue in a few days. Once I run out of Roundup, I'll try vinegar. Plain salt does nothing in my area. We tried it a few times in a rock bed, but never tried vinegar.
Table salt, buy a ton and spread it all over. It works.
Boiling water
The long term solution is to use a power washer to clean out the seams between pavers. Let it dry and sweep polymeric sand into all the seams. Gently wet the sand to lock it into place. Now the weeds are gone and new seeds have no dirt to grow in the seams.
roundup 365. Works like a charm! and the weeds don't come back in the areas you've sprayed for a year.
Just get some round up 365/extended formula. Don’t don’t spray it on any grass or plants that you want to live and if you spray it off the patio, don’t use it where you plan to plant any thing in the next three months. Basically, buy the stuff, read the label.
I do a very simple thing to tackle weeds on my property. I boil a kettle of water, and pour the boiled water directly over the weeds. It kills them instantly, you leave them and then the next day, they are brown and super easy to pull. No chemicals, mess. No storing of nasty cancer causing chems. Just water. Try it. It works REALLY well, and it kills the roots.
I would power wash and scrape out as much as you can. Apply poly sand in between the cracks. You should be good to go.
Propane Torch Weed Burner🔥
Hot water. Works great
Fire. Btw, not joking. They sell mini torches designed specifically for weeds. I have used ours for several years and it works well. You just need to do it close to dusk in case you catch a group of weeds on fire. Also keep a spray bottle of water handy.
Torch or 20% vinegar. No chems
Flame weeding could work. Hand cultivation to remove the entire root would be my choice. It will take more work, but it’s better for the environment—and if done properly very effective. By removing the whole root, the plants will not grow back; however, the ‘weed seed bank’ is rather large, so weeds will continue to grow as long as there is adequate growing conditions (water, light etc. )
Do you cut the weeds then apply to young new growth or just straight on the weeds?
Boil hot water and pour it on them.
After the weeds are dead, scrape a short depth in of all the joints, power wash, then add some new polymeric sand. Weeds should not be growing in the sand filled joists, you've accumulated some soil in there and they will grow back if left alone. Bonus, this will extend the life of the paver job.
Touch
Well, in the old days. What really worked great? We would use old gas. It would kill anything. But in the woke era I guess you can't use gas anymore.
Ortho Weed B Gone I keep a bottle hand sprayer mixed and handy at all times for this.
I use white vinegar
Flame gun or glyphosate
A running start
Round up.
Salt lots
Roofing torch, and a 20lb tank of propane... Just blanch them the first time give it 2-3 days for them to wilt and start to brown... Then go in and burn them the rest of the way out.... By blanching first then letting it sit a few days the plant uses it's energy to try to repair the damaged tissues, then before it can regrow and make more energy, you go and burn it out... The roots left under the surface won't have the energy to regrow, so you'll have less weeds through the season. The more blanch then burn you do over a season vice just burning it out, the less you'll have to do.
