Please ID this spurge-like weed! (Southern Cal)
This weed completely took over our lawn over the spring and summer, so we decided to start over. It came back.
It starts off very shallow-rooted, red stems and eventually sprouts a grean leaf. Then, it spreads very similar to spurge, however the roots and stems become very thick, eventually sprawling over the entire lawn, sometimes more than a foot long. Please help in identification so we can figure out how to get rid of these suckers!
