Well I use the Lasagna method and completely organic in my beds and garden. But I do it a bit differently than most, and you are not going to like what I say, but it works. When I start a new bed, I start in the fall. I first hit the area with Round UP, wait a week and hit it again, then wait another week. Then I just scalp the area and remove the debris. OK here is my secret. I donÂt use newspaper, I use heavy duty card board and lay is down on the dead grass, then build up the bed with whatever I got. Wait till spring, plant, and use a heavy layer of Mulch. Now I am in TX, but with you being in GA, Bermuda will try to invade, there is just no way around it. If you have the beds built up correctly, it is very easy to control by just pulling what shows up. I promise you the grass growing along the edge of the bed will see that nice fertile moist soil, and it will cross the barrier to get in.

No one asking anyone to read ALL those replies. If you do not want to know what we know, skip our replies. On a new thread or topic, we will come over & reply & you will be back where you are now. jolj(7b/8a) henry, I am going to try solarization on my bahia grass. 90% of the things on this thread will not eradicate bahia grass. This includes round up, which kills the tops, but not the deep roots. Round up will not kill nut sage/ nut grass or common dew berry vines. So I will try this on the bahia. I have heard that the solarization may kill the soil food web, when it kills the weeds. I am planning to sheet compost the beds after I kill the grass/ weeds. I have been told that tilling kills the soil food web. Not sure who is right or if it matters, I give vegetables away every season including the winter. I grow more then I can use, then I must be doing something right. [Like[(https://www.houzz.com/discussions/organic-way-to-get-rid-of-bermuda-grass-dsvw-vd~1521679) I did this in 2011 & it worked great.

That is bermudagrass and the only way to reduce its growth and development in your St. Augustine is by promoting an environment that is more beneficial for St. Augustine and less beneficial for bermudagrass. In addition, the use of Atrazine herbicide at specific times of the year can help reduce your bermuda encroachment. I'm not nearly as experienced with St. Augustine as are some others on this forum, so I'll step aside and let them guide you to St. Augustine success.

Texazgal, did you see anything at Walmart that said it was a grass only killer? Thanks for checking on it, but I'm thinking if it says WEED 'AND' grass killer it may not be a product like Grass-B-Gone that kills only grass and which can be safely sprayed on broad leaf plants without harming them in the least. I haven't been to Lowe's yet to see what kind of grass only killer product they might be carrying now.
