Yes, to your concerns. It is time to consider more drought-resistant shrubs such as spiraeas, barberry, smoke tree, and euonymus and local nurseries are now offering more native plants such as sword fern, salal, and huckleberry that can handle drier summers.  I have been giving lectures about this topic and will be doing a seminar over Zoom on "The Changing Garden and Changing Gardener" as part of the Thurston County Master Gardeners fundraiser.  If you visit my website at www.binettigarden.com you will see information on how to sign up for this Zoom lecture along with other places I am speaking in person. Thanks for reaching out and noticing how our gardens need to change. The good news is we can still have a lush and beautiful landscape in the Puget Sound area with the proper placement of the right plants. Add organic matter to the soil to hold more moisture and use mulch and proper watering techniques.  Gardens and gardeners will learn to adapt. Keep growing, Marianne Binetti
