Black Bindweed, Greater Bindweed, Field bindweed, Convolvulus and Cornbind are long clambering vines. Their large trumpet flower and heart shaped leaves are a common site in gardens, waste areas and along roads.
Bindweeds can smother new plantings, blocking out light. They die back in winter, but leaves rhizomes underground, making them difficult to spray out until leaves reappear in spring.
Autumn is the best time to spray bindweed foliage initially, but it is important to then re-spray any regrowth in spring.
