Propagation
Take stem cuttings during summer.

Note:
It is controlled by hand removal or raking and rolling it up into a pile to be composted or bagged then removed off site. Spraying glyphosate 1% solution has minimal effect due to the waxy surface of the leaves.
This plant is easy to remove but soon returns and requires follow up weeding to eradicate. 

Contact with the leaves may cause skin irritation especially for dogs.
