This stuff isn't worth the shipping and the shipping is free. I used it once and nothing happened. Two weeks later I re-read the directions, mixed it a little stronger with the same results. I should of put 82.50 in a blender and dumped it on the lawn. Everything else I bought here has worked great. I had to give it one star because it won't let you give a zero.
The website shows that this product can be used on St. Augustine grasses. I was extremely disappointed when I received this product and read in the instructions that it could not be used for Floratam. This variety of St. Augustine, widely used in Florida, should have been called out on the web description since the directions for use give several caution alerts and even stress that this not be used in Floratam in all CAPS!
$90 down the drain.
