Bonide Weed Beater Ultra will work best in temperatures around 55 degrees to 85 degrees. You could potentially apply this product to weeds that are actively growing, however Bonide Weed Beater Ultra may injure certain cultivars of St. Augustine such as Floratam, per the product label. We would recommend that you test a small area for tolerance first, or select a product that does not exclude Floratam if you have that type of grass.
