We have many different post-emergent herbicides that can be used on St. Augustine and Centipede grasses. In general, you should not spray herbicides when temperatures are over 90 degrees since your turfgrass will be under more stress during these times. Please let us know what specific weeds you are targeting so that we can better assist you in selecting a product to fit your needs!
