As I mentioned earlier, salt might be ok if water doesn't flush the salt into the yard. After a few rains, he might be upset..... I wouldn't do it.

I'd Round-Up it, and grade it often.

X2 on the 2 4 D. It doesn't kill half of what I see on your driveway, only broadleaf. And J-Mech is right on the glyphosate as well. This is what you need to kill everything, and like he said, nothing that you can get over the counter is going to last you 12 months. For a cheaper and less toxic solution, you can mix some clorox in water and spray it on them. It will kill everything it touches as well so long as you don't dilute it too thin. This won't last as long as round up though.

If you are spraying this stuff, don't do it without a respirator. This stuff is a bad carcinogenic.

I don't know where the myth is that Roundup lasts for months. Maybe in retail stores there is a mix of Roundup and something else, one for a burndown and the other for "season long" control. All I know Is I use real Roundup (power max I believe) and I have to come back 2-3 times over the summer to keep weeds and grass at bay. In fields, a crop generally takes over and provides so much competition that a new crop of weeds can't survive. The 2-4-D products I use on fallow land don't have any carryover that I have observed either. I try to alternate away from glyphospate when I can so as not to contribute to herbicide resistance.

Respirator when applying bleach?
What about the millions that use it everyday in the laundry?
None wear respirators.
If people are stupid enough to stand down wind while spraying it, well it just shows Darwinism is real.

glyphosate has to be absorbed by the plant via foliage.
It will kill the plant and the roots so it won't come back.
But seeds might be dormant in the ground for years before they sprout.
Maybe after annual treatment with glypho for several years the amount of sprouts will be less and less.
But birds and wind are always adding more seeds.

No sir. Glyphosate.

Surely you know it has a high toxicity. I apologize if my post was confusing.

No, I don't want to use salt. I get this with heavy rain!

Tractor Supply sells this, and it will keep everything dead for 2-3 years,,,

https://www.tractorsupply.com/tsc/pr...cide-2-1-2-gal

At one time we had nothing that could kill Johnson grass,,
We tried Pramitol, it did kill the Johnson grass, but, in 3 years, the first plant that would grow in that spot was,,,,, Johnson grass,,,

Johnson grass is next to impossible to kill. BTDT. WE don't have much of it here.

Pramitol is only a single season killer. It does have residual, but if you kill what is there at the root, it would likely appear to work for a few seasons. It's made to kill at the root, and is a bare ground herbicide. However, it too can spread, and with the flooding that drive takes, I still wouldn't use it. It can spread. I'm surprised TSC carries that. I thought you had to have an applicators license to buy it. It must not be full strength.

Well. If it helps, heres the torch I use on all my patios and my brick walkway. I just burn em all then sweep or blow them away. I only have to do it once per year and its instant gratification. No waiting for chemicals to soak in.

Roundup causes the plant to be unable to uptake water, so it dies of drought.
I spray my driveway 2x a year. I guarantee the grass/weeds it has killed, do not regrow.
What grows, is new seed that is there.
2 qt. in 20 gal will exterminate anything growing, but if a seed germinates the next day, roundup will not stop it.
Spray while the plant is actively growing and @ least 24 hours before a rain.
Do not spray when it is Hot-- *90 --- or cold *40, as the weed will be slow to uptake the Glyphosate.
Occasionally you might encounter a weed that has mutated, and will be roundup resistant, but that is not the norm.
If you have weeds that are waxy like button weed, a Non-Ionic Surfactant added will allow the Glyphosate to translocate into the weed better.
