There are many factors to consider on how much and how often you should water, but Colorado Springs Utilities provides some good info to consider at https://www.csu.org/Pages/Wateringyouryard.aspx and a fact sheet of how to "cycle and soak" water to maximize your watering efficiency by watering a little bit at a time is available at https://www.csu.org/CSUDocuments/cyclesoak.pdf
- Adjust sprinklers so only your lawn is watered and not the house, sidewalk, or street.
- Water in the morning or evening when temperatures are cooler to minimize evaporation.
- If water runs off your lawn easily, split your watering time into shorter periods to allow for better absorption. Learn about this technique by watching a short video on cycle soak irrigation.
- Adjust your lawn mower to a higher setting. A taller lawn shades roots and holds soil moisture better than if it is closely clipped.
- Check the root zone of your lawn or garden for moisture before watering using a spade or trowel. If it’s still moist two inches under the soil surface, you still have enough water.
- Choose shrubs and ground covers instead of turf for hard-to-water areas such as steep slopes and isolated strips.
- Walkways and patios provide space that doesn't ever need to be watered. These useful "rooms" also add value to your property.
- Spread a layer of organic mulch around plants to retain moisture.
