Yard care and water savings tips

  • Think twice before using pesticides. Scientists have found 23 pesticides (weed and bug killers) in our local streams, many at levels that may damage salmon and other wildlife. Overuse of these products can also damage soil and plant health.
  • Start with prevention — Build healthy soil with compost and mulch — soil organisms protect plants from many diseases and insect pest problems.
  • Select pest-resistant plants and put them in the sun/shade and soil conditions they like.
  • Clean up diseased plants and compost dead plants in fall to reduce hiding places for insect pests.
  • Pull weeds before they go to seed and spread.
  • Use a variety of plants, so if pests attack one plant, others can fill its place.
  • Identify the problem before you spray, squash or stomp. The problem could really be incorrect mowing or pruning, improper watering, or other easily corrected practices.
  • Accept a little damage — give nature time to work. Natural predators often bring pests under control, but they need time to work. Don’t spray at the first sign of damage — nature may control it for you, or plants often just outgrow the damage.
