Yard care and water savings tips
• Remember that not all brown spots in your lawn are caused from lack of water. If you have distinct irregularly shaped brown spots — the symptoms are most severe in late summer, and the section of dead turf can be pulled up easily — the problem is probably grubs, a beetle larva. They feed on your turf’s root system and kill it. If you question what is causing your turf problem, contact the county WSU Extension Office or a nursery professional. They will probably want to see a sample of your turf.
• Take the pets outside to be bathed. Pick a dry spot in the lawn to wash them.
• Wash vehicles at a carwash that recycles its water. If washing at home, make sure the hose has a shut off valve.
