I just added fertilizer to my lawn. It's well established and about to add micro nutrients, etc. The yard has had nothing done to it for years. It's Saint Augustine I live in the gulf coast of Texas. I need to spray RoundUp for Southern Lawns. To get rid of weeds. So when should I add the Growth Inhibitor. I spent years confined to bed. But now able to walk again. PTL
T-Nex Plant Growth Regulator should be applied when the lawn if actively growing and will last for 8 weeks. Depending on the type of turfgrass you have, the application rates should be adjusted based on the grass height at application. Please view the Application Rate Table on the product label for application rates for your turfgrass. The lower the height of cut of the particular turfgrass species, the less material is required to provide the desired turf growth regulator effect.
