A comprehensive guide to the most common weeds of the Pacific Northwest, with essential information on their management and eradication Winner of the 2025 Award of Excellence: Horticulture from The Council on Botanical and Horticultural Libraries   Weeds are everywhere. They crowd out valuable agricultural crops, compete with the tomatoes and beans in your vegetable garden, spread rampantly along roadsides, and pop up from the tiniest cracks in sidewalks. In order to manage them, we must first learn how to identify them.   Weeds of the Pacific Northwest  is a guide to identifying, controlling, and eradicating over 300 species of weeds that gardeners and homeowners are likely to encounter in Northern California, Oregon, Washington, and British Columbia. Though they can all cause trouble, each weed is different. The hundreds of user-friendly photographs and detailed descriptions of each species here ensure that you can spot and treat any weed in your path.  As the experts behind this book demonstrate, some plants can be killed by eating them, some by digging, some by smothering, and some only by the judicious application of chemical herbicides—and it is very important for you and your neighbors to know and understand the differences.    “A hardworking identification guide to regional weeds and an important look at their impact on biodiversity, agricultural economics and gardeners’ peace of mind….. Weeds of the Pacific Northwest  is filled with valuable information about the plants we gardeners love to hate, and how to deal with their inevitable presence in our growing spaces.”― The Seattle Times Mark Turner has more than 30 years of experience photographing garden and native plants for books and magazines.
