Hedge bindweed, Calystegia sepium, is able to spread rapidly to creep between cultivated plants, making it difficult to eradicate. It’s able to re-grow from small pieces of cream-white root, so cultivating a border often aids its spread. It can make large clumps of foliage, obscuring and smothering small plants. Seed is produced following the cream-white trumpet flowers, which also allows this weed to spread.
This climbing, twining perennial dies down in winter but grows rapidly in spring and summer to smother other plants.

Dig up cultivated plants in the dormant season and wash roots thoroughly to remove soil and allow the fleshy cream-white roots of the bindweed to be removed. Alternatively, cut back the stems of the bindweed as soon as they emerge. This will weaken the plants, and should be repeated as soon as re-growth emerges. When forking through infested borders, remove every piece of bindweed root.
Use a systemic weedkiller on the leaves as soon as they appear in spring. Use plastic food bags placed over the foliage, spraying inside and holding in place with a clothes peg. Re-apply throughout the growing season, as growth continues, at four to six week intervals.
