It’s a medium to high-maintenance grass that produces a dense sod (like a carpet) and tends to crowd out most weeds and other grasses. Because of its dense growth habit and ability to withstand heavy foot traffic, St. Augustine sod is often used on golf courses, sports fields, and in other high-traffic areas.
