AI vision has detected common broadleaf weeds. Broadleaf weeds generally don’t really need to be identified for the purposes of controlling them in a lawn. The vast majority of broadleaf weeds can be controlled with 3 way herbicides, which are herbicides that contain 3 of the following active ingredients: 2,4-d, dicamba, mcpp (mecoprop), mcpa, fluroxypyr, triclopyr, quinclorac, carfentrazone, etc. Note: triclopyr and fluroxypyr are especially useful for hard-to-control broadleaf weeds such as clover, ground ivy, and wild violets. Repeat applications of any product are typically required in cases of severe infestations/mature weeds.
Apply spring pre-emergents when the 5 day average soil temps are in the 50-55F range. Or use [this tracker](https://gddtracker.msu.edu/).
If you have a question about pre-emergents, read the entire label. If you still have a question, read the entire label again.
Pre-emergents are used to prevent the germination of specific weed seeds. They don’t kill existing weeds.
Most broadleaf weeds you see in the spring can’t be prevented with normal pre emergents. You’d need to apply a specialty broadleaf pre emergent in the FALL.

Speedzone with an ionic surfactant

My go to when my yard looks like this is a mix of T zone SE and Tenacity. Spot spray all the weeds. Wait two weeks, then do it again. Within a month they will all be dead. I’ve never had it harm my grass (TTTF and KBG)
I follow the recommended measurements of each per gallon and mix them together
T- Zone. Sprayed the yard a week ago. Weeds are starting to brown and die off.

I like Tenacity for my tall fescue. I can’t really make out what exact type of grass that you have so double-check that it’s ok for your lawn.

I’ve had great results with mixing Speedzone and Hi-Yield Triclopyr Ester. The Ester is good for targeting clover and ground ivy.

We’re spraying Momentum 4-score this spring. Been getting really good results from it.

Speedzone is your friend.
Look it up on DoMyOwn, and apply when temps are less than 85 degrees

You’ve got a few good options already mentioned. I personally hand pull a few weeds every time I’m outside or going to or from my car. Like 3-5mins every day.

Speedzone or Q4 work awesome. Don’t waste money on insanely underdosed crap that they sell at Home Depot.

Tenacity is not great or even good in my experience using it over 4 seasons. I still deal with quite amount of weeds every season, and tenacity bleaches and thins out my fescue. I have not tried crossbow yet, but a number of top commenters and posters on this thread have recommended crossbow.

I have had luck with Tenacity. Expensive, but there are now generics out there for much less.

Speed zone works great on the early season weeds.

Trillion. Idk if y’all get it in the states though. 2-4D and MCPA and Dicamba.

I pull them. When they’re that big they are easy to grab.

Your lawn really needs an aeration and overseed application, 5lbs seed : 1,000 sq ft. This will help a thick mat of grass outcompete the weeds as you kill them off. The window of opportunity is closing quickly if you’re in the Pacific Northwest.

I’m brand new to lawn care. Is roundup suggested or no?

Consider contacting your local landscape supply store — one that sells fescue sod/seed — and ask what they recommend. You’ll benefit from local knowledge, will form a friendly relationship when looking for other advice in the future, and will likely find the product(s) you need in stock when you need them.
I follow my local store’s expert advice to the letter and have the best lawn around. When people ask me my secret, I say, “Whatever Carolina Fresh Farms tells me to do, I do it.”

I’ve only manually pulled weeds and I’m PNW cool season, I know store stuff is weak but I grabbed ortho weedclear hose end product. Have all sorts of grass seed from over the years, kbg, pnw fescue mixes etc. Want to kill all that stuff plus rampant crabgrass. Is the ortho okay or should I just get better stuff? Want to overseed after application. Is it better to do weed killer with long or mowed grass or does it matter?

T Zone SE with a surfactant. I spray once a week, but only on new weeds. In clover, I do spray weekly as it seems to bounce back better than other broadleafs. Never had it hurt my fescue at all.
Substantial_Bad2843
I have the same grass and my local place has always sold me Fertilome Weed Free Zone and it’s worked perfectly for years. Seems like a big pump for SpeedZone, but its ingredients look identical.

I just used Speedzone here in Ohio and it’s doing some absolute carnage on my weeds. I should have used it a while ago.
I first did spot spray and that didn’t kill my grass, so then afterwards I ended up doing a blanket spray on my entire yard. I’d recommend it, just make sure you get the Speedzone for cool season grasses.
