How Much St. Augustinegrass Seed Per 1,000 Square Feet?

NC State Extension's lawn chapter does not give a pounds-per-area figure for St. Augustinegrass. The planting method it points to is vegetative: sod or plugs.

There is no overseeding rate, because there is no seeding rate. A warm-season mowing height and a germination time are not verified, so they are not borrowed from bermudagrass or from the cool-season sheet.

If you came here to buy seed, stop at this page and use the sod calculator with the roll size your supplier prints. This page will not convert area into pounds of seed.

Common St. Augustinegrass Seeding Mistakes

  • Entering a made-up pounds-per-thousand figure. The result stays on no seed rate.
  • Using the bermudagrass hulled band as a stand-in. The grasses are not given the same rate.
  • Expecting a germination countdown. Germination is not verified, and the plant is not established from seed in the source we cite.
