Vetch, vetch, and more vetch! My yard is being overtaken by this viney weed. As you can see, it is thick and it covers anything it can climb over - including the rose bush and the rhododendron in my front yard.
On July 4th, my son decided to attack the vetch, for which I was very thankful. Soon he came in to tell me that he'd found a "Robin's nest" when he had pulled the vetch off the rhododendron (which is about 5 ft. tall).
