I use this product on Bermuda, St. Augustine, and Centipede grasses in the Fall and Spring. My weed growth has been reduced by 90%. Easy to use and well priced.
Product was packaged good-- bag had not broken or gotten wet. It was easy to spread over yard. Will not know results right away, but should be all right.
I laid down the preemergent on my west FL Flortam grass. The grass liked it turn mostly nice green. Will apply early spring as well and hopefully stop weeds.
