Summer Fertilization

Cool-season grasses:

  • Tall fescue and Kentucky Bluegrass - Do not fertilize again until September.

Warm-season grasses:

  • Bahiagrass - fertilize in mid-June at 1.0 lb. of nitrogen per 1,000 sq.ft.
  • Centipedegrass - delay fertilization until mid-June and then apply 0.5 to 1.0 lb. of nitrogen for the entire growing season.
  • Bermudagrass - fertilize every 4 to 6 weeks at 1.0 lb. of nitrogen per 1,000 sq.ft. each time during the growing season approximately three weeks after the turf is completely green.
  • Zoysiagrass - fertilize again during mid-summer at 1.0 lb. of nitrogen per 1,000 sq.ft.
  • St.Augustinegrass - fertilize in June and early August at 1.0 lb. of nitrogen per 1,000 sq.ft.

These rates are for the Piedmont and coastal plain. If you are growing warm-season grasses in the Mountains, adjust the rates down by 1/3 to account for a shorter growing season.
