Frequently Asked Questions

What weed killer can I use on Saint Augustine grass?

There are a variety of weed killers that can be used on Saint Augustine grass, but the most effective is probably Roundup. Roundup is a glyphosate-based herbicide that is effective at killing a wide variety of weeds, including many that are resistant to other herbicides. It is important to follow the instructions on the Roundup label carefully, as it can damage other plants if used improperly.

How do I get rid of weeds without killing St. Augustine grass?

Weed control in St. Augustine grass (Stenotaphrum secundatum) lawns can be a challenging task because most herbicides that are effective on common lawn weeds will also damage or kill St. Augustine grass. Preemergent herbicides are the most effective means of controlling weeds in a St. Augustine grass lawn, but they must be applied before the weeds germinate and emerge from the soil. There are several preemergent herbicides available that will control common lawn weeds such as crabgrass (Digitaria spp.), spurge (Euphorbia spp.), and oxalis (Oxalis spp.) without harming St. Augustine grass.

The best time to apply these herbicides is in late winter or early spring before the weeds start to germinate.
