Hedge bindweed problems — and how to fix them
Hedge bindweed (Calystegia sepium) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

Even small root fragments left in soil will regenerate; physical root barriers 60 cm deep are the only reliable containment method.
Smothering garden plants
The twining stems wind tightly around host plants and can girdle and kill shrubs or perennials if left unmanaged through the growing season.
Herbicide resistance challenges
Deep roots mean systemic herbicides (glyphosate) must be applied repeatedly to young growth to gradually exhaust the root reserves; a single application is rarely sufficient.
