I have lived here over 35 years and the situation I described intensified in the last few years. I fertilize twice most every year and have a sprinkler system. The main reason I posted is that in recent years some unidentified weed grasses now are taking over long standing centipede stands. I suppose that the trees are taller so I am dealing with more shade but its just curious that a good standby like centipede all of a sudden can no longer hold its on.

I am open to trying some bahiagrass against these intruders. Anyon have experience with the Argentine bahiagrass vs the more domestic varieties?

I live in central GA and have struggled with my lawn for years. Since there are a lot of trees on my lot I have found that St Augustine is my best choice but there are some sunny areas where I want Centipede to grow. They problem is that I have seeded areas with Centipede and put down sod only to watch over a couple of years for weeds and other grasses to take over and crowd out the Centipede completely. Some of these grasses look good in midsummer but die off quickly in August and creating bare spots.

I have tried fescues in these ares and in shady ares but it always dies out in Summer. I have read you can't use them in our area although they work fine 100 miles north in Atlanta.

My lot is hilly with lots of slope, and is completely sandy. I can push a rod 3 feet down with very little resistance.

Any and all advice welcome as I get ready to try again this spring.
