Practice good lawn maintenance: Mow your lawn at the suggested height for the grass type that you have, and never remove more than a third of the total height of your lawn in one mowing. Be sure your lawn mower blade is sharp in order to make clean cuts, and keep your mower in good working condition during the season when it's used the most. Water less often but more deeply to encourage deep grass roots; they will come in handy during our typically dry summers. Always follow any water restrictions or watering guidelines for your area, but consider adding a rain sensor to your automatic irrigation system. It will automatically turn off your system if you've had rain so your lawn is not overwatered.
