I live in Colorado and I have a horrible Canadian Thistle weed problem in my vegetable garden. How can I get rid of these annoying weeds? How can I prep my garden next year so that I don't have this same infestation?

Canadian thistle is a noxious weed in Colorado and Colorado State University Cooperative Extension has prepared several publications on it. For home gardeners, go to There's a more extensive publication for rangelands, but it contains details that may be useful. Good luck!
