Rain season is coming. One yard care choice can help protect salmon.

Salmon move through King County streams every fall, just when the Pacific Northwest's rainy season kicks off. That surge of rain can wash pesticides from lawns and gardens into storm drains and local waterways.

So, before you consider your next lawn treatment, ask yourself this: Can I solve this problem without a pesticide?

Often, you can!

Seeing chewed leaves?

Take a closer look before treating the plant. The culprit insect may be a beneficial bug that feeds on pests, and plants can often outgrow minor damage. If pests are causing a problem, try removing them by hand, using a barrier or trap, or pruning affected parts.

Dealing with weeds?

Pull them before they go to seed and spread. Mulch garden beds to reduce new weeds, or use a long-handled weed puller for dandelions.

Not sure what’s wrong with a plant?

The cause may be its growing conditions, such as watering, pruning, or whether it’s suited for its location. Identifying the problem helps you choose an effective response. If the same plant struggles every year, consider replacing it with one better-suited to the site.

Pesticides: The last resort

If you do need to use a pesticide, use the least toxic product that will work, treat only the affected area, and follow the label's instructions carefully. Keep products away from drains, and don’t apply them when rain could wash them away.

One less unnecessary pesticide treatment means one less source of chemicals that rain could carry toward local streams. Celebrate Salmon SEEson by making salmon-friendly changes in your yard care.
