The battle against bindweed is never-ending! I found bindweed growing out of the side of a friend's house. On the lefthand side of this photo is a rosebush, covered in bindweed that was allowed to grow out of control. The bindweed found an opening in the siding and grew right through it! Bindweed is a noxious perennial weed that has an extensive root system. Hand-pulling generally does not kill it and we haven't found an effective organic herbicide for bindweed. Herbicides that contain 2,4-D are effective, but you'll probably have to make several applications. Bath recommends using Fertilome Weed-Free Zone.
