Those are cleavers, I believe. Had them all over where I grew up. Search google for cleavers....

Cleavers. Because it cleaves. Very invasive weed. If I had a smaller garden/yard I might eventually get rid of it by pulling, mowing, weedeating it before it seeds, but so far have not managed it. I hate the stuff. It can actually give you a rash or burn if you rake your arm across it.

Scintific name Galium aparine; another common name is bedstraw.

Thanks, they are gone. At least it's shallow rooted and hasn't flowered yet
