Yes, Roundup will smoke it (pardon the pun) but it will also kill your desireable turf also. The link had a lot of info but you can go buy what you need at Home Depot or lowes to control it and not hurt your lawn.
I Got It Too !Have this weed taking over my yard, Anyone know what it's called and better yet, How to get rid of it, Thanks'
Yup, that’s what we called them growing up. A good measure of how tough a kid you were in the 70’s was whether you could barefoot it through a yard full of stickers. Had them about 12 years ago in our yard and used the hose in Scott’s x2 treatments one spring and they finally thinned out here.blast from the past huh lol... thats stickers... lol dont believe me, let the yard dry up and step on them barefoot lol
