Better Homes & Gardens has published a weed identification slideshow with excellent photos to help you weed with confidence.
Garden Club members agree - we've seen nearly ALL of these weeds in our gardens at one time or another (typically every year). The sooner we tackle them, the better our gardens grow, and look, without unsightly weeds in the picture.
The photo above is showing a closeup of a common garden nemesis: bindweed. It will choke out everything else if you don't keep it under control!
