The Damage Control For Convulvulus arvensis
The methods of treatment for Convulvulus arvensis can be both digging and systematic weedkiller containing glyphosate.
Digging
To dig your convulvulus arvensis, you will need to spade up any seedlings as they appear; removing as much as the root as possible. However, this will need to continue for several of the growing seasons to fully eradicate the weed.
Once you have dug up the roots, make sure to either burn or send the waste to your local council’s green waste collection. This is because your own home compost will unlikely be hot enough to kill the roots.
