It is either spurge or oxalis or something else. Please ID and
recommend treatment. background info: I live in Florida. I have a St.
Augustine lawn. There are a lot of these creeping over on my lawn. It
has covered some parts of my lawn.
It grows from the soil and extends over the lawn like a blanket.
I've been hand weeding them, but they are very fragile, and tend to
break easily, leaving the base in the soil.
Please ID and recommend a treatment.
