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.

The good news is that it’s definitely a broadleaf weed, since grassy weed controloptions in St. Augustine are limited. It doesn’t look like spurge to me, butit could be oxalis (yellow woodsorrel) or Black Medic.

Post emergent options would be atrazine or something like WeedZone formulated forSt. Augustine–it contains 2,4-D and dicamba. Normally 2,4-D is not thought ofas safe for SA but this product is labeled for SA. It may be too late to apply any ofthese now since many herbicides warn against using them in dormant grass.
