What type of weed is this and how do i kill it?

Question

i seeded my yard about three weeks ago and it is growing great. a little thin which is probably some of the reason why i have weeds popping up. i'll have to overseed it again. but this little weed is all over. i can't find a picture that looks similar online . what type of weed is it and what do you recommend to do on a newly seeded tall fescue yard? I've posted links to the pictures below...

thanks for the replies so far.

i don't believe that it is creeping charlie. it is not a creeping weed. they are individually tap rooted weeds with 2-4 leafy pedals on each one. it looks nothing like the viny creeping weed in the picture of your source. ..

redletter... it could possibly be that mallow that you linked to. i'll have to look into that some more.

Answer 1

Do you think it's one of these?

Answer 2

What you have is creeping Charlie.If you don't have the purple flowers yet, you will. It is I believe a wild ground cover.
If there's more creeping Charlie than grass in your lawn, it may be easier to start over by killing all the vegetation and reseeding the lawn.

Herbicide applications should be made when the weeds are actively growing. Mid to late autumn, after the first frost, is an excellent time to apply herbicides to creeping Charlie and other perennial broadleaf weeds. At this time the plants are busily sending food reserves to the roots, so the herbicide is moved down to the roots as well, resulting in better control. Make a second application 3 to 4 weeks later for best results. Applications can be made again the following spring, but wait until the plants are in bloom (April to June) as the plants are most susceptible to herbicides then. Again, a second application may be necessary.

For best results make applications when temperatures are in the mid 60s to low 80s, there is no rain expected for 24 hours following application, and there is little or no wind. When applying herbicides to lawns, don't mow the area for a few days before and after application.

Controlling creeping Charlie takes some work and is frequently not totally successful. Herbicide applications may be needed on a regular basis for many years to completely eliminate the weed. It may be easier to just learn to live with it, and periodically knock back the weed when it becomes too dense.
