Maintaining an effective irrigation system can prevent more water waste than any other landscape practice. Yet, it is often the most overlooked method of conserving water.

Take time to examine your irrigation system at least once each month. Check for:

• broken sprinkler heads
• sunken sprinkler heads
• unmatched sprinkler heads
• non-vertical sprinkler heads
• clogged drip emitters

If brown spots occur in turfgrass areas, conduct a "can test" to check for spray uniformity, as described in the Lawn Watering Guide.

Often brown spots occur because trees or shrubs were added after the initial sprinkler system was designed and installed. In this case, add extra heads if the existing heads cannot be adjusted accordingly.

Brown spots may also be caused by female dogs, disease or insects. These problems can be identified by a professional consultant or by the biologist at the Agricultural Commissioner's office located in Victorville.
