Here are pictures of the bindweed.
The "humps" are the 3 rose bushes and a peony plant that are being strangled.
Then there's a Yucca and last one is a sign that a Rose is still giving life while being strangled.
My only concern about digging out the plants and setting them somewhere else is that the bindweed could potentially replant itself in the new location.
Fortunately, we live a stone throw away from the U.S. and DH has been wanting to get over there to buy personal quantities of Killex and round up.
If I do anything, I think I'm just going to wait till fall and make the attempt. It's just so frustrating to see the bed in this condition and can only hope there will be life underneath this predator.
