Small plants can be dug out. Ensure all of the rhizomes are removed and disposed of via your household rubbish collection or at your local transfer station. Do not compost as convolvulus can re-sprout from fragments.

For convolvulus that is growing up trees you wish to protect, cut all easily accessible vines close to the ground. This will kill off the top growth and enable it to be pulled down later. The remains of the plant anchored to the ground can be dug out or sprayed with an approved chemical registered for controlling convolvulus. Contact your local gardening centre, agri-chemical supplier or the current agri-chemical manual for chemical advice. When using herbicides always use in accordance with the manufacturer’s instructions.
