    Dollar weed can be a PITA. I find granular weed & feed with Atrazine best suppress them. But they will be back because just like sedge there is no pre emerge that works on them. They will push through the thickest St Augustine turf to re emerge. Over watering will cause Dollar weed, but once established they survive drought.
