Lawn Management Tips

  1. Apply about 2.5 cm (1 in.) of water not more than once per week (Deep Watering).
  2. To measure this amount – place an empty tuna can on your lawn while watering, and measure how long it takes for the water level to reach the top of the can.
  3. Skip watering your lawn for a week after a good rain.
  4. Deep watering as described above, is better than frequent, shallow watering because it encourages deep roots.
  5. Watering before 9 am reduces evaporation and scorching of leaves from the sun.
  6. Watering on calm days prevents wind drift and evaporation.
  7. Set up your sprinkler to avoid other surfaces such as driveways, sidewalks and patios.  Water running down the curb is money down the drain.     
  8. Water slowly to avoid run-off and ensure absorption.
  9. Collect rainwater from your roof in a rain barrel and cover it with an insect screen - direct the down spout of your eavestroughs into the rain barrel.
  10. Choose an efficient watering system – for example, soaker hoses have tiny pores that emit water slowly and directly to the soil.


Overwatering lawn may cause:
  • It to turn yellow and develop fungus and diseases;
  • Thatch and fertilizer leaching;
  • Oxygen and mineral restriction on heavy clay soils.

Mowing and Lawn Treatments

  • Avoid mowing and unnecessary traffic on your lawn if the lawn is dry or starting to turn brown
  • Don't cut your lawn too short - cut no lower than 6 – 8 cm (2.5 - 3 in) so that the roots are shaded and better able to hold water
  • Aerate your lawn once a year in the early spring or fall to improve water penetration, and then also consider: 
    • applying a thin layer (no more than 15 mm – 0.6 in) of organic material;
    • raking to distribute evenly, and;
    • overseeding at this time to help thicken the lawn.
