Here on the South Carolina coast, we tend to have long warm and wet spells in December and January. For instance today, 12/28, it's in the low 70's and we've had rain 2 of the last 3 days.
We had new Centipede sod put down in August, and it's doing relatively well, but I haven't used any fertilizers or weed & feed on it yet based on my research indicating it wasn't good to apply to new sod or right before the winter season. (Maybe that research is flawed.) I was in the backyard yesterday, and we're starting to get a variety of weeds sprouting up through the sod. I don't want to damage the grass, but I know these weeds spread like gangbusters especially during this time of year when the weather is like this. The grass is largely dormant, so it's not actively growing to help combat it.
What is the recommended course of action for treating this type of grass at this time of year?
