Talkback: Five ways to eradicate weeds
Another good way of getting rid of bindweed is to unwind it from the plants it is strangling and shove the whole bindweed into a plastic bag, then spray into the bag, shake it around and spray again. Tie it tightly and just leave it in place. Not very pretty, but you can hide it under some leaves. This is very effective and not too time consuming. It's also safe for the surrounding plants.
