Hi, bindweed will creep in from pathways, the plot next door, or from deep underground. We have lots of it and in heavy clay it just snaps, so can't be removed completely- EVER!!! Life is definitely too short, so we just pull up the shoots when we see them, and keep pulling it. My father in law gave me a great piece of advice when I started gardening-no plant can survive without it's leaves, so keep pulling them off & the plant will eventually die. Has worked for everything-except bindweed. Learn to love it???
