From Canada. I found the cure, to this horrible weed that was taking over my lawn and garden. if you don't mind using chemicals. I hate using them , however felt I did not have a choice in this situation.
We had poor quality soil delivered, and got invaded by the bindweed in the lawn and the flower beds. It was everywhere, absolutely terrible.I used the "sandwish bag and Roundup" strategy, that is some roundup in a plastic sandwish bag held around the weed by and elastic. It looked really weird on my lawn, all those little "pony tails". But then it did kill the weeds, and i had less and less,. after 3 years, the bindweed is almost gone, I found only 3 this year that received the same treatment.Part of the lawn got damaged by some Roubdup leeks and I had to reseed some bold spots here and there, but that was not too bad.The beauty of the treatment is that when you treat one weed, yopu actually kill more than one because the roots are all mixed together.
