Depends on the weed and what you want to get rid of. I think you are keeping the bermuda, is that right? Besides clover, what weeds do you have?

With any weed-service contract, you have to expect that the chemical used might not kill ALL species of the weeds you have. It would be better for you to do some research into the particular weed--see what is effective on it. When a liquid broadleafed weed killer is used, it is recommended to water the area first....water it rather well, then wait for an hour. This acts as a capilliary action to draw the weed killer down to the roots of the weeds. Often, in warm areas, weed killers are used on nice, windless days, during the hottest part of the day and a lot of the liquid evaporates or runs away from where you want it. The watering first can help defeat that. Dependent on what kind of grass will stand up to broadleafed weeds might be another thing to look at. Generally, if you have tough weeds, then a second application is warranted. But, do give the first application a chance to work. Overkill will only hurt your soil and its ability to grow grass. If your grass, what grass you do have, is poor, that suggests your soil is not up to scratch. Whether you dig in organic matter or just layer it over the surface is up to you. But, if you can see your way to putting a layer ...1/2" - 1" of compost or good topsoil, over the area lawn in spring and fall....and do that for the next four years minimum, this will often result in much improved lawn. I realize in your neck of the woods, being a transitional state---through middle America, you might use a number of types of grass. What you have to do is find a type expressly for your circumstances....and stick with it. In the north, we regularly use a combination seed...Kentucky Blue...for sun; perennial ryegrass for toughness--able to take heavy traffic, and fescue for where shade might come on it. The independent grasses don't take on their own color or growth, they swim together and makes for a nice lawn. In your area, such combo wouldn't work....it would burn the first time your Oklahoma summer hit it. But, a combination of grasses you do use, might work. What do your neighbors use....what success does your neighbors have with lawns and does the local full-service garden nurseries give any advice. You might go to your local state funded university EXTENSION SERVICE, provided by such institutions. Thus, Oklahoma State and other colleges are at your beckon call. They have agriculture departments and many do soil tests at nominal charge, or free of charge. After all, they are funded by you....the Oklahoma taxpayer. A phone call might tell you if, and how to go about submitting a soil test. (actually its 'soil tests'....they require multiple samples from different parts of your property to give an accurate up-to-date result.

1-2 2% roundup solution 3x a year. let the stuff grow somewhat or the whole of the plant may not die. and dont over spray and 'top kill' the veg. if one top kills all thruout their prep season, there are many things in an oldfield that live thru that process. 3 seed in the fall. the more years of prep the better. u say u had an old field and those can be full of tough weeds. maybe 2 years is a better start. 4 if u were gonna till it, i would have liked to see that started last fall already for 2005 fall planting. yes, it brings up weedseeds but isnt that what the roundup is for? given that there are many many diff kinds of soils, i think the jury is still out on this step but im in the camp of leave the soil surface alone, man has worked it enough... 5 u get what u pay for. i dont think $1700/acre is too little. u also dont need to put everything on all at once. maybe a more basic $1300 this fall and slowly adding in $3-400 worth of specific spp. into the future. but being a novice, this maybe more advanced than u need. 6 there are many, many in wisconsin. and price does not always = quality or quanity. remember PLS is ur friend. u have all summer, maybe visit some nurseries and check out what they got... most of us prairie ppl dont bite and like to talk about our wears. froggy

OK...it has been a month and no other answers. What happened. Did the herbicides work? Now that you are this far, what do you think you might/should have done differently. Some folks might not like my way of killing off things in my yard (and not using chemicals), but I pour boiling water on unwanted roots. It shows results quickly; however, you might also destroy some of the insects that are there. Of course once all the green stuff is gone, the insects might decide to move someplace else anyway. How about a new picture?
