Thank you Larry and Kate. I have been fighting bindweeds for a long long time. After hiring different persons for weeding, I hired called a landscaper and garden center and they covered my whole yard with a very strong weed barrier , except where I had roses and irises, then put 2 inches of mulch. It does not work. When I wanted to plant more roses, I discovered that yards long bindweed roots are growing happily underneath the weed barrier. I am in the process of taking off the weed barrier while also digging and getting all the roots of the bindweeds. Was very proud when I managed to get an about 2-yards plus long bindweed root out. Took a picture on my iPhone----will post if I can.
Apparently irises do not like to be planted above the weed barriers, although the soil above it is about 6-8 inches deep. They all died, not one single one survived. I managed to clean 1/2 of my left half front yard. I am curious whether all the Bermuda grass and bindweeds really are gone there. I have to remember to keep a hawk eye to that part and immediately get them when they reappear! Wish me luck to get the other 3/4 of the front yard clean too! I am an old woman, but used a two-prong rose aerator to dig deep to get to the roots and then use other hand tools, like a cobrahead trowel or something like that.
