Rain Barrel illustration Rain barrel info and resources for the Pacific Northwest
How to set up rain barrels to water your plants while reducing your water bill, and where to buy them. Using rain barrels helps reduce stormwater runoff, recharges groundwater, and leaves some water in tapped rivers so aquatic creatures can live there.

Also, learn about GroCo compost, a clean, nutrient-rich compost.

Noxious weed illustration Identify noxious weeds where you live. Aggressive exotic plants can produce immense numbers of long-lived seeds and may overwhelm native species, degrade habitat for wildlife, stick, stab and poke, and may even poison livestock or burn your skin. To help eradicate invasive weeds, King County provides a Web site with Noxious Weeds Identifications and practices for control of select weeds, and we're available to answer your questions at the Noxious Weed line, 206-296-0290.

Save money and time on chemicals and watering

To get involved in natural yard and garden care, contact Doug Rice at 206-296-8360 for free classes and information. The Natural Yardcare Neighborhoods Program can help an entire neighborhood go natural! Here are some easy tips to try now:

  1. Grasscycle: Mow high, mow often and leave clippings to help fertilize your lawn. Grasscycling can provide almost ¼ of your lawn's fertilizer needs.
  2. Fertilize moderately in September and May with natural organic or slow release fertilizers or compost. Avoid weed and feed.
  3. Water your lawn deeply but less often to grow hardy, deep roots. A weekly sprinkling of about an inch of water in the morning or evening is best. See more water conservation tips.
  4. Improve lawns with aeration, overseeding, or compost. Or consider rebuilding the soil and replanting.
  5. Protect your kids and pets by using bug and weed killers sparingly, if at all. Lawn chemicals can be tracked into your house or rubbed off onto toys and skin.
  6. On steep slopes, in shady areas and near lakes, ponds, and streams replace lawns with native plants that can thrive in those tricky spots. The right plants will help slow the runoff of rain, soil and chemicals, and provide you with a beautiful Northwest look.
