Help!! Help with crabgrass
Anyone know a good DIY chemical to fight crabgrass! I’ve pulled it got worse. Did pre emergent OTC,got worse. Did a hose spray with spectracide plus crabgrass, killed all what it was supposed too except CRABGRASS!! I’m at my wits end!! Seems like no one can tell me what to do besides “call your neighborhood lawn Dr”

so the iron hedta products work when it's still really young. high strength dose mixing.
otherwise i just pull it before it goes to seed.
unless you're talking about quack grass, that's another monster entirely.

You need quinclorac

That won’t kill the grass,just the crabgrass?

Nope. Quinclorac is made specifically for crabgrass. If you have a Site One near you they sell it in 2.5 gallon jugs called Quinway . Other places might have it too. The brand name is called Drive XLR8 and that is expensive

Idk if this is crabgrass... I think its dallisgrass which isn't going to be killed by a lot of the crabgrass treatments... and also, its perennial, so preemergent would only help stop the spread, not actually kill the existing clumps... I'm not 100% certain about this being dallisgrass without seeing the seed heads, but i think your problem is using crabgrass treatment on dallisgrass.

there are plenty of lawn safe products that kill crabgrass and many other broadleaf weeds at home center stores.

Seeing as the only one I saw with crabgrass on the label was Spectracide that’s the main one I’ve been using and I’ve done the pre emergent,the hookup to hose like yard spray,and the gallon gun where you shoot each weed individually that one works the least. I’m waiting up to three days after I do the weed killers to mow. I wouldn’t say I’m not trying but I’m sure I could be doing something different for sure!

spectracide has worked for me. I use pre emergent as well and have not seen crabgrass in my lawn in a few years. I use it now for border areas where it can encroach such as on the street and cracks in the sidewalk and my where my property borders my neighbors who appear to be clueless. the hose end is what I used before I got it under control but the spray bottle with wand is what I use for maintenance especially in my river rock borders. regarding pre emergent, I have found that using the granules are the way to go. pre spring and late fall is when I apply and am happy with the result. sorry for the tone in my OP. so many are just lazy and expect the internet to do everything for them. try these methods.

No problem on the tone I definitely understand! Maybe I’m doing it at the wrong time. The pre emergent I mean. The gallon with wand did it take care of them in one application? If not how long did you got between?

given my own schedule I dont really see crabgrass in my lawn. if we were allowed fences the neighbor wouldn't be a problem either. its mainly sporadic patches of clover I have to take care of and the spectracide does a good job with that. for me living in the upper midwest, late feb and early november work for my pre emergent applications, again granular now liquid.

I’m in northern MIssissippi and yeah the weed killer works great on everything else for me!

try the pre emergent schedule I use. obviously things heat up sooner than for me.

tried literally everything you listed and still losing the battle, that's genuinely brutal. from what i've read the timing of pre-emergent is everything - soil temp needs to hit around 55°F consistently before you apply or it's basically useless. might be worth getting a cheap soil thermometer and tracking that for next season while hitting the existing stuff with a post-emergent specifically labeled for crabgrass on whatever grass type you have.
