Our regions water consumption near doubles in the summer months in part due to do outdoor irrigation. Given the most common residential landscape in the CRD continues to be the lawn, it's where we often see the most water waste.
During our hot, dry summers, soil can develop a top, crust layer that is difficult for water to penetrate and absorb, resulting in water running off down driveways and sidewalks into storm drains.
To avoid this water waste, introduce the Cycle and Soak irrigation method. Turn your watering system or sprinkler on for one minute and then shut off. This allows the water to slowly absorb and penetrate this top, dry layer. After 10 minutes, turn your system back on to provide the full water application your garden or lawn needs. Soil is now able to absorb the water and penetrate down into plant roots, where the water is needed. Remember it just takes one, your lawn needs a maximum of one inch (25 mm) of water each week, including rainfall. Deep, infrequent watering promotes a strong root system, which is better able to obtain water and nutrients and withstand dry spells.
Reducing evaporation from your lawn and garden can cut down on water waste and means you can water less often. Mow grass to a height of 5-6 cm to keep roots shaded and better able to retain water. Leave grass clippings on the lawn for mini mulch to reduce evaporation.
Water waste can also be reduced by aerating compacted areas of your lawns so air, water and nutrients can reach the roots. This can be done easily by poking holes in the lawn and top soil down to six to eight centimeters using a gardening fork. Manual and powered aerators are also available.
Install a micro/drip irrigation system that uses low-water-volume irrigation components (under 20 gallons per hour), at low pressure (under 25 psi) to deliver a precise amount of water to the root zone of plants, where it is needed most. Water is applied slowly, which allows water to penetrate the soil reducing runoff and evaporation. These systems can be tailored effectively to individual plant and garden needs.
