Outdoor Water Conservation

Irrigation Inspection

General Tips

  • Power of design. There are a number of ways to create a water-efficient landscape.    
  • Let it grow. Let your grass grow to a height of 2.5 inches. Taller grass shades new growth and reduces evaporation. You can also leave the grass clippings on the lawn.        
  • Add organic compost and mulch. Compost and mulch are great for gardens. Both can act as a protective cover for plants, keeping the soil cool and moist and discouraging weed growth. Organic mulches like pine bark, shredded cedar, or wood chips are ideal. Avoid rocks as they retain heat, increasing the need to water. Read more about the benefits of compost.     Water Wise
  • Sharpen your blade. Keep the blades of your mower sharp. Dull blades tear the grass leaving it open to disease and heat stress.
  • Over-seed. Introduce a mix of drought tolerant fescue grasses to your existing turf. Over-seeding should be done while fertilizing, top-dressing or aerating.
  • Avoid high-nitrogen fertilizers. They promote temporary growth only and lead to shallow roots.
  • Efficient Irrigation System. Ensure your irrigation system is doing it's job by checking the sprinkler heads regularly and setting the timer properly. Inefficient systems can become a huge and unnecessary water waster.   
  • Know when to water. The best times are between 10 p.m. and 6 a.m. Avoid watering in the hot sun as almost 50 per cent of the water will be lost to evaporation.
  • Know how much & often to water. While there is no formula to watering, the following is a general guide for how much water an Okanagan lawn needs in an average year:
