Relax guy, no problem Mon. You got new sod laid late in the season, you are going to have weeds so get use to it. Personally I would not worry about the Poa, but if it irritates you spray everything green with Round Up. Just make sure the Bermuda is dormant. In the meantime relax until the end of February. Last week of February or first week of March Apply a product called AMAZE. It is a long half life Pre-Emergence herbicide. Water it in and relax for a few of weeks. Once you are certain all chances of frost have past, get the lawn mower out and scalp the lawn down. I do not mean down to dirt, but enough to get all the dormant brown grass blades cut. Rake up all the debris and relax again for a few weeks until the weather warms up. Once you see some green sprigs of Bermuda growing after it starts to warm up, apply your first fertilizer application using a balanced fertilizer. Go to your local Home Depot and buy some Lesco 20-5-10 or 15-5-10 to do the job. Apply at the proper rate of 5 pounds per 1000/ft2 and water it in. From that point on find the BERMUDA BIBLE and follow the directions and RELAX.

so you know from experience that Brush Master works for killing wisteria? and if so, what was your particular methodology for application?

Corn Gluten Meal can be an effective pre emergent control for plants growing from seeds but it is not effective for plants growing from roots. Your "weed" is a grass so the most effective control is a grass killer which will also kill off the grass you want to grow. Talk with the people at your local office of the Texas A M Cooperative Extension Service about what you have and how, maybe to get rid of it. http://agrilifeextension.tamu.edu/ kimmq is kimmsr

There is no "weed" killer that can be used safely, whether in your vegetable garden or elsewhere. Any plant poison you use will also kill your vegetables. Ragweed, Common or Great, is an annual and in my experience it does not have a real extensive root system, although in some soils pulling it can be a bit difficult if the plant Is two feet tall or more. Around here cutting Ragweed off at soil level is often enough to stop it.. Bermuda is an invasive grass that you need to remove every bit of root from the soil if you do not want it growing somewhere and place good barriers to prevent the roots from moving back into that area. Newspaper and cardboard, or any other mulch material, will not work controlling that or any other invasive plant. kimmq is kimmsr
