How To Keep Your Lawn Healthy In The Fall

  • Mow. Mow your grass at a height of 2½ to 3 inches.
  • Water. Even though it is cooler in the fall, lawns still need regular watering to maintain plant health and better survive winter conditions. Water until the ground begins to freeze.
  • Fertilize. Mid-to late October is the best time of year to fertilize your lawn. Fertilizer provides grass with nutrients for spring growth. Use zero phosphorous lawn fertilizer unless you are establishing a new lawn or you have a soil test that indicates additional phosphorus is needed. Look for a middle number of 0 on the fertilizer package. Water your lawn for 1 to 2 hours after fertilizer application.
  • Control Weeds. September is the best time of year to treat dandelions, plantain, clover and creeping charlie. Limited numbers of weeds should be removed by hand or spot-treated with herbicide.
  • Sweep Up. Sweep up and reuse lawn care products that fall on streets, sidewalk and driveways.
