Hi Yield Weed and Grass Stopper with Dimension Herbicide can be used as early as February and as late as May in St. Augustine grass depending on where you live. We would recommend using a pre-emergent as soon as the soil temperature reaches 55 degrees Fahrenheit to prevent weeds before they come up.
Please check out our Warm Season Lawn Guide for information on when to use products in your lawn.
