I use a propane flamethrower/torch. It’s so fun to use.

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.

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!

I think you can pour boiling water over it to kill roots in cracks. Or blowtorch if you’re feeling frisky.

I would recommend pulling them by hand, then laying paver sand. A nice thick layer should last you the year at least

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.

Industrial / horticultural vinegar. It’s 40+ percent acetic acid. You can get it on Amazon if you can’t find it elsewhere. Spray ’em.

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.

Round up. Pulling won’t work.

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.

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

Eraser Max if you’re not averse to herbicides. It has glyphosate and imazapyr in it so you get a quick kill from the glyphosate and residual control from the imazapyr. Plus, you can buy it in quart size so you’re not having to store 2.5 gallons of something you only use a little bit of once a year.

Weed wack then spray.

I’ve battle the same scenario for years. Paving sand didn’t work. I tried fire, weedeating, pulling, and sprays. In the end, the longest lasting solution was using Roundup Max Control 365.

Vinegar in a spray bottle if you want to avoid herbicides.
Spectracide weed killer if you don’t mind herbicides.
Just be careful, as either could kill grass on contact.

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.

Leave them. They’re beautiful.

Based on my one summer working as grass maintenance for the borough, spray diesel fuel on it. But then it’s super slippery

Well I just came across a company that now sells a small flame throwing robot dog. Just saying

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.

Burn them.

Pour boiling water from a kettle. Kills them in a day and it has no smell and is super easy
