Is there a way of getting rid of bindweed?

Bindweed is one of the most persistent weeds, and if there were an easy, reliable way of getting rid of it, someone would be very rich today! In my experience, it is almost impossible to completely eradicate it, and you can hope only to control it. Here are a few methods that you can try.
1. Cover the whole area with carpet or other weed-suppressing material for at least a year, so that lack of light eventually kills off the roots. Be careful of shoots running out from the edges of the covering.
2. Carefully dig over the infested area, and remove the white roots. If you can then leave the area for a few months over the growing season, the roots you missed will resprout, and you can go at it again.
3. Spray off the entire area with weedkiller, leave for a few months, and spray off again when new growth has appeared and is growing strongly. If you use a weedkiller, wear protective gloves and eyewear, and follow the instructions on the packaging carefully. Note that bindweed wilts naturally in autumn, and there will be no regrowth until spring. Weedkillers work best in spring and summer when growth is strong.
4. If you cannot start with a clean bed, that is, if there are shrubs or perennials that cannot be moved, then you can spot-treat the bindweed. Stick bamboo canes into the ground so that the bindweed twines up them, and when there is good growth, brush on weedkiller, but be careful not to get it on the surrounding plants. You may need to do this over a period of two or three years.
5. Use any of the methods above, combined.
