This started growing in areas where I added new topsoil and planted new grass seed; likely from seeds infiltrated in the soil or the bale of hay. If left untreated, it will grow up to 3-4ft. The stalk is sturdy and more flat than round.
Will I have to nuke everything including the lawn and re-seed? :( Or is there some sort of selective herbicide the I can use on these? Any help would be appreciated. I tried tenacity but we are two weeks in now and it didn't help.
