Convolvulus is a creeping and climbing weed sometimes referred to as bindweed. It is a difficult to control weed.
Common convolvulus are climbing and scrambling weeds with large white or blue/purple trumpet flowers similar to that of morning glory. The weeds scramble and climb by winding their stems around other upright plants, trees and fences. The roots are deep and have rhizomes.
Its vegetative reproduction means that control by digging out is rarely enough on its own. Systemic herbicide should be used repeatedly to kill the weed and its root system.
*Cut vines at waist height (summer-autumn) and spray foliage below; the more of the weed that is sprayed the better the control will be.
