I have several patches of wild Bermuda grass that are brown and appear dormant in my Bahiagrass lawn. Can I use Roundup to control the grass, and can I reseed now?
The Bermuda has to be green and growing for the Roundup to be effective. Also it may take more than one application to control most of the runners. It’s best to spray once when the spring growth begins and then wait a few weeks to see if some of the dormant sprigs begin to sprout. Then you can apply Roundup again and wait a few more weeks before tilling the soil and seeding new grass.
