I too am levering out bindweed from the kitchen garden on a daily basis; though I will confess that I’m standing solidly on the hate side of any love-hate relationship with it. I have a border which was plagued with bindweed so I removed all the plants and covered the ground with black polythene for 2 years. That does seem to have helped a lot, but not completely, but looking at black polythene for 2 years wasn’t pretty!
