Nzoner's Game Room>Best weed killer for lawns with rocks landscaping
scho63 12:03 PM 03-19-2021
The last two weeks the weeds have come out and grown with vengeance all over the lawn between all the rocks.

I need to find something that will kill it all and last.

I prefer to have a ready-to-use product rather than a concentrate to mix in a sprayer I would have to buy.

The ground is hard and dry here in AZ so not sure if it is wise to water a little first before applying the weed killer.

I know Ortho and Roundup are the two big ones many homeowners use.

I don't have a huge yard but have weeds coming up all over. I'm sure the landscapers didn't put down a tarp to block the weeks or it was done poorly.

Any advice appreciated.

Yeah. Different chemicals have different shelf lives. Typically settling out is a bigger issue than expiration.

Yeah. That’s not what you want. LOL.

WTH, I'm a lot further south than you and my entire yard is still pretty dormant.
I do some spot work, but hired a lawn company. For the same price as the product and me doing it with streaks, they can do it without streaks.

I was expecting a simple Product A is better than Product B and C because....

Instead I got a whole lesson in Botany and Chemistry! :-)

some things to consider...you said you want something that lasts...thats a residual.. Look at Preen, its a granular you scatter and water in. Active ingredient will kill all grassy plants even sandbur plus small seeded broadleaf weeds. Apply heavy, wont impact desirable plants already growing.

For existing, Roundup is your best bet

Avoid weed b gone, it is a volatile product and can hurt the landscape plants it is trimec and 2,4-d

for yard its fine....but sounds like u hired pros for that, never a bad idea

I used to use this 30 years ago. It had a skull and crossbones on it back then and it became too dangerous to use. But it was the greatest. You’d see results within a few hours on a hot day. Haven’t used it since the mid 90’s. It’s like the chlordane of weed killer.

It’s the opposite of chlordane. It doesn’t have any residual control at all. It’s purely a contact killer. It works by entering in the cell and oxidizing it. It doesn’t translocate, it’s not systemic. It just burns the fuck out of everything.

That being said, DO NOT USE THIS. It’s dangerous as all fuck. I have a closed automated tendering system, and a pressurized carbon filtered cab. Don’t handle it. Even the mist coming off the nozzle can damage your lungs.

DO NOT USE THIS.
As it turns out, it enters your cells and oxidizes them too.

Wife used to work for Syngenta.. Seed side. not Chem side.


I also think hardware store roundup is not as good as elevator roundup

Seriously though, are they lava rocks? I kept my lava rocks looking sharp with a propane weed burner. Best to do the weed killer as well, but burning off the dead stuff and stuff that blows in it is the way to go. Burning alone won’t kill them permanently so you need to do both.

I used Ortho Ground Clear for $34 at Home Depot. It covered every weed and a little extra double coverage. I blasted the shit out of the weeds. 95% are dead already.

This shit is the bomb!

I was kidding with the chlordane. I actually took a bath with that shit about 30 years ago on a hot day. My lungs feel great. You forgot to mention it has stench in it too. It’s definitely a burning agent herbicide that really isn’t supposed to kill the roots, but does lol and it is dangerous

And Buehler is right, don’t use it. But I don’t think scho could buy it even if he tried too. You need a pesticide license to purchase shit like that in my state. But it really is the best.

I also had to kill wasps hiding in crevices on my porch. Those fuckers are dead too! :-)

Yeah. You have to have a permit.

Glad you came out of the spill OK. Some aren’t so lucky.

If it got in your eyes it might be a different story.

But you definitely need a carbon filter and eye protection if you’re going to use a hand sprayer.

Diesel fuel is a great weed killer.:-)
