What is the process to use to kill the weeds in my st. Augustine grass. I

Scott's Weed and Feed if it's a nice healthy lawn. Unless you have
those weeds that have "spurs". I can't think of the name of them right
now, but there is only one product that will kill them. It's very
expensive and you have to get it from a specialty store. Home Depot or
Lowes doesn't carry it.

Globe sedge is what it's called, and it is very hard to get rid of.
Some lawn services won't even guarantee complete removal.

Our lawn service and the neighbor's were surprised when we got rid of
dollar weed (southern version) with Weed B Gone. Worked very quickly on
a lawn that was covered with it. The little that remained was spot
treated and S.A. grass fills in pretty quickly...good reason to use
after fertilizing grass.
