I have the Dunes West cruddy clay soil with centipede sod installed 3 years ago.
Wondering what others with similar soil/grass are applying right now for weed control and to develop thicker, better yard?
The pre-emergent crabgrass control should have been spread in early March. The other flowering weeds that you see should be pulled up by hand to keep them from spreading -- any flower in your lawn is a weed, and any weed will spread it's seed.
The grass greens up near the coast around mid April, that's when you should spread the Fertilizer. They sell a special blend for Southern Lawns with no Phosphorus (the middle number in 15-0-15). We have plenty of Phosphate in the soil around here.
Once the centipede gets established, there isn't much to do. Weeds are usually relegated to thinner less established parts of the lawn. Keep away from phosphorus and tone down on the nitrogen once it's established. Too much nitrogen and the roots start rotting because they trap too much moisture.
Whatever you do don't drive on it. It drives me nuts when people leave park with two wheels in the grass when they park on the curb.
I don't have irrigation and my lawn slowly died. It looks like the sand on the beach right now.
