Grass burs (also called sandburs) are common in sandy lawns. Like most lawn weeds, grass burs are opportunists?they thrive when grass is struggling to survive. Proper mowing, fertilization, and irrigation develop a dense turf that will quickly choke out grass burs. In other words, give your lawn plenty of TLC. Preemergence herbicides are best for getting rid of grass burs. Use a product that contains oryzalin or pendimethalin. Follow the application instructions carefully.
