Question
I just built a house and had Bermuda grass sod lad down about a month ago. I waited until it was about 4.5" to mow for the first time. I have all kinds of weeds growing in it now, thin grass like and broad leaf weeds. I need to know what I should do to help my grass be the best in the neighborhood and get rid of the weeds. Also, I have a yard sprinkler system, what is the best way to set it up so that my yard will get the water it needs. I live in northwest Arkansas and most of the dirt is rocky dirt or red clay. Thanks,

Kenny

Kenneth:
You, probably have the same type soil we have here, a Georgeville clay.  It is a fine soil if treated right.
I am afraid to find out what type of grass-like weed you describe.  If it is another grass, you are fine.  You can wait until winter to treat it with Roundup, or equivalent, when Bermuda is dormant.  Make sure that it is dormant and not growing below the brown tops of leaves.
Alternately, you can use a 2-4D variant, a mixture with other chemicals which is very effective against non-grass weeds.  Check with your local ag agent to find out which he recommends for you area.  There are many.
If the grass-like weed in nutsedge, nutgrass, or whatever you may call it there, you will have some years of treatment before relief.  It is tough.
Broadleaves should go away after a few treatments.
Once you are satified with weed treatment, you may consider an application of high quality compost for the turf (and plant beds as well as trees.)  In dormant season, apply 3/8 inch per thousand sq. ft., or one yard per thousand feet, to your lawn,  This will build the soil, fertilize the lawn, fight fungus, and build soil moisture retention for droughts if done over several years.
Good luck.
