Monthly Lawn Care Calendar


January

  • Be careful not to overfertilize and overwater annual ryegrass.  If temperatures are warm and humid, monitor for the disease pythium (cottony blight).

Top

February

  • Fertilize winter ryegrass if you did not in January with a complete fertilizer and continue to mow it regularly.
  • Keep all lawn herbicide sprays away from the root-zones of ornamentals.

Top

March

  • Fertilize grass with a 12-4-8 or 16-4-8 at the end of the month after green-up and when no more frosts are predicted.  Make sure the fertilizer contains slow release nitrogen.
  • A pre-emergent herbicide can be applied at the first of the month to control summer annual weeds.
  • Renovate areas with sod, plugs, or sprigs of an appropriate grass for your landscape conditions.

April

  • If you did not fertilizer your lawn last month now is the time.  Fertilize grass with a 12-4-8 or 16-4-8 and make sure the fertilizer contains slow release nitrogen.
  • Water the turf only when needed.  Check the soil to a depth of 1 inch for moisture.
  • Sharpen the blades on your mower before you begin mowing.  Remember to sharpen them throughout the mowing season to prevent damaging your grass.
  • Wait until the end of the month to seed lawns.

May

  • Mow lawn at the proper height, careful not to remove more than 1/3 of the leaf blade.  Do not collect clippings unless there is a disease problem.

Top

June

  • Water lawns when the grass shows signs of water stress.
  • Scout your grass for signs of insects or damage, if the weather is hot and dry, look carefully for chinch bugs in St. Augustinegrass.
  • Apply mole cricket bait later this month if necessary.
  • Remember to sharpen mower blades.
  • If daytime temperatures are above 85 degrees F, do not apply herbicides to turf.

Top

July

  • Water your lawn only when it shows signs of stress, such ash folded leaf blades and bluish cast.  Add water by allowing the soil to become wet to a depth of several inches.
  • If there are signs of mole crickets in your lawn, apply mole cricket bait according to the label directions. Do not water in or apply when rain is predicted.
  • Keep checking for chinch bugs in St. Augustinegrass and spittlebug in Centipedegrass.

Top

August

  • Apply a winterizer to centipedegrass to give the grass cold hardiness.  Use a fertilizer with a 2-1-3 analysis such as 10-5-14.

Top

September

  • If your St. Augustinegrass needs fertilizing, use a winterizer with a 2-1-3 analysis.  The winterizer will give the grass cold hardiness.
  • Check St. Augustinegrass for signs of sod webworm damage (grass blades with chewed edges).  If weather conditions are hot and dry, continue to watch for chinch bugs.
  • There is no need to treat summer annual weeds now with an herbicide since cooler temperatures will kill them.  Wait until February or march to begin a management program.

October

  • Add water to your lawn during dry periods.
  • Continue to monitor for sod webworms.
  • Seed annual ryegrass when daytime temperatures stay in the 70's at the rate of 10 lbs per 1000 sq. ft.  Water lightly each day until the seeds germinate.

  • Fertilize ryegrass with a complete fertilizer after you have mowed a few times.  Use a rate of 1/2 lb. of nitrogen per 1000 sq. ft.
  • Water lawns when dry.  Check soil moisture to make sure water is needed.
