    Q
    What is Floratam St . Augustine grass? How can I tell the difference?
    I have St Augustine grass. I am considering to purchase Bayer Advanced Weed Killer for St Augustine grass. Thank you.
    A

    Bayer Advanced Southern Lawn Concentrate Weed Killer is labeled for St. Augustine but is NOT to be used on Floratam version of St. Augustine. If you are uncertain of which type of St. Augustine grass you have, we recommend you contact your Master Gardener here for proper identification. Both of these types of turf lawns are very sensitive and can be damaged very easily.

    Below are some characteristic differences between the two versions of Saint Augustine Grass. 

    Saint Augustine Grass:

    This broad-bladed, medium-green turf grass thrives in sunny locations, but unlike some sun-loving grasses, it also has a high shade tolerance. Common St. Augustine grass grows quickly during summer, but more slowly in fall and spring. It is a salt- and drought-tolerant grass that requires moderate maintenance. 

    Floratam Saint Augustine:

    Floratam is coarse-textured grass, but a distinguishing feature of Floratam is its longer and wider leaf blades. This dark-green cultivar grows rapidly in both spring and summer. It is less cold and shade tolerant than other St. Augustine grass cultivars and can suffer from freeze damage when temperatures stay below freezing for an extended period of time. Floratam needs plenty of sunshine and will perform poorly if it receives less than six hours of sunlight a day.
