My Lawn Needs Help
I'm looking for some advice on how to improve my lawn. With this past summer's drought here in Houston TX, several spots in my yard died. Since then, I've installed a sprinkler system so something like this hopefully won't happen again. However, the problem now is weed control in the spots where the grass died.
Previously, I raked up the dead grass. I did see new grass starting to grow; however, weeds also grew. I was pulling the weeds for a while, but it seems like they're getting worse. Now, the spots are getting overwhelmed with weeds.
Is there a recommended herbicide I can use to kill the weeds that is actually effective? I've tried a few I got a Home Depot but they don't seem to be too effective. I don't have kids or pets if that matters. Am I to the point where I use Roundup on the weed/grass areas and replant sod in the spring? I would prefer to let the grass regrow on its own, but I'm getting desperate to get the weeds under control.
Any advice will be greatly appreciated. I have St Augustine Grass.
