I grew up on a farm, where the main objective was to annihilate everything that wasn't corn, soybeans, or cotton, and it has been ingrained in me since my formidable years... Now that I'm an adult, and have decided that I want an acceptable yard so my neighborhood doesn't judge me as hard, I'm struggling with the concept of not killing grass, but killing everything else...

So with that, if I have a smorgasbord of shite, broadleaf and unwanted grasses, and the only thing I want left is my patchy Bermuda and St. Augustine competing against each other, what is my best option?

I have some form of a lot of products on hand in the farm's chemical room. I just want to know what my best shot is.

Atrazine and dual, baw, pre-emerge just like with corn and milo. The LSU AgCenter weed book says Bermuda and St. Aug are tolerant of both chemicals. A nice lawn is a mofo if you're resurrecting one like I am currently. I'm fighting dallis grass and some weed that shrugged off atrazine currently.

Yeah I'm in the same boat. Bought the house in March so didn't get to lay down anything in the fall, now I'm just trying to get it looking decent to get through the year... I'm already tired of mowing weeds every time I catch a break from the farm.

If your trees have a lot of undergrowth under the canopy I would hire a tree guy to allow more light to hit the lawn. Then change your mowing height to 3 or 3.5 inches, which will give your Bermuda and St. Aug a chance to smother and out-compete those weeds. At that height the grasses will also produce seed and propagate more quickly. Last suggestion is to go with frequent spot-treatment every few weeks rather than relying on a spring / fall whole-lawn weed-n-feed treatment. Probably need to uproot crabgrass manually and before they produce seed. After 2-3 summers you should have a lush carpet of St. Aug with much less work to maintain.

The worst thing you can do is to cut low and put too much faith in weed-n-feed.
