Need some help with this weed type. I have it in a few sections of my lawn. Also, suggestions on how to get rid of it.
The majority of it grows in a square patch of the lawn where a childrens jungle gym used to be (previous owners)

Looks like some sort of fennel. Use your normal broadleaf herbicide but the T-Zone by Gordon's (contains Triclopyr) would be best depending on your air temperature. Try not to use it in temperatures over 85 degrees.
