Unfortunately we do not have the spreader settings for that specific combo and the manufacturer does not list that spreader on their Ferti-lome St. Augustine Weed and Feed 15-0-4 bag. Due to the thousands of granules on the market and just as many different types of spreaders, you will want to calibrate your spreader to the product you are using and its application rates. You can see a short video on how to accomplish this here.
Ferti-lome St. Augustine Weed and Feed 15-0-4 is only labeled for burclover.
We recommend using a soil analysis test kit or taking a sample of your soil to your local cooperative extension so your soil can be analyzed to determine what nutrients your soil is lacking. The healthiest, hardiest lawns are fertilized 2-4 times per year, fall, summer, early spring and late spring. Ferti-lome St. Augustine Weed and Feed 15-0-4 could be used if the nutrients it provides are what your lawn needs.
We do have soil test kits here.
Ferti-Lome St. Augustine Weed and Feed 15-0-4 is labeled to treat Virginia Pepperweed.
It is labeled for crabgrass but not for horsetail. We recommend that you consult with your local cooperative extension office Master Gardener for a recommendation for a St. Augustine turf in your area.
