The Q&A Archives: CRABGRASS

Question: Its been 4 weeks since I installed floratam sod. Its bearly getting green but, there is an emergance of crabgrass all over my grass. Please help! DO I use crabgrass killer?

Answer: Agralawn Crabgrass Killer is the only product I know of that is safe to use on your floratam turf. It contains baking soda which, for some reason, attacks crabgrass but not St. Augustine (floratam). You can try using regular baking soda on a test area of your lawn. It should kill the crabgrass. If so, you can use it over the entire lawn without harm if you cannot find Agralawn Crabgrass Killer. Next winter you will want to apply a pre-emergent to your turf so you can avoid dealing with crabgrass altogether.
