I used Ortho Weed b Gone with 2 4 D but all it did is wilt slightly.

Anything with 24D should kill it. How long ago did you spray it? It'll wilt within hours, but it may take a week or two to die.

Easier to use pre-emergent in Feb and March.

Wow... thank you for posting this. I hopped on here to post the exact same question except for weeds in general.

Scotts weed and feed will kill them fast. It is granular treatment for lawns.

I just sprayed about 4-5 days ago. I'm just impatient I guess. Sprayed a second time yesterday, and some again today that still look healthy.

Jut eat them they are quite edible .LOL

Just 2,4D Plain from any farm store or such should kill most all broad leaf weeds, do the spray while the weed is in the growing stage for best results and on a dry/sunny day so the stuff doesn't all run off, it has to absorb through the leaf and be pulled into the roots, any thing sprayed on the ground is wasted.
A gallon of Amine 400 concentrate is about $22 here and will mix a lot of spray.

I put them in my salads ...... not the tough old leaves I used to give them and the roots to the rabbits when I still had rabbits

Use Grazon Next. Not exactly listed for lawns, but you'll only have to spray once. Works super. It's for pasture use, I guess that is grass. Best to spray in late fall, even into November.

Try the knife and fork thing first ... you may like it. I do with a simple vinaigrette

Don't poison wildlife. bees use them for the first food of the season.

Trimec 992

I use Weed B Gone Max. It has three broadleaf chemicals in the mix. It’s better! It really helps if you spray when there hasn’t been any rain the day before, the day you spray and for 24 hours after you spray. The last tip is to spray when it’s about 70 degrees (11 am?) and the weeds are actively growing so they take up the spray. Then, just wet the leaf, don’t drown it. Try to spray before the wind picks up, use low pressure, large droplet spray, otherwise you will have some drift and kill the wife’s tomatoes. If your bottle froze over winter, try using a stronger concentration.

A preemergence product only works on seeds, not established plants. Use both.

They are hard to kill this time of the year, even with round-up. Hit them with 24-d after the first frost in the fall and they go down like a house of cards. Mike

Ok honestly. I am against spraying chemicals around just so the place looks nice. I hate golfers for that very reason. If it aint grass .... short and stiff .... kill it. Dandelion has a bunch of iron and more vitamin C then oranges pound for pound. So unless you are trying to impress the neighbors with a nice green sheet of green that needs constant attention. Just eat the fecking stuff and be done with it ...... Sorry, PC gland has hiccups

diesel fuel-off road preferably.

I let them grow. My bees prefer to work them over just about anything that blooms in the spring. When dandelions bloom = time to put on honey supers.

I try to keep the yard nice because I'm allergic to the dandelions, and if I don't keep up with the yard, the kids will wear trails down into it like cattle and turn it into a mud pit like hogs I use whatever concentrate Ace hardware has that says broadleaf on it. I'm not sure what the chemical is.
