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.
