Glyphosate will see it off-but you would need to carefully treat the
leaves
of the garlic and not get it on the shrubs.
A safer way is to slice of the leaves just below soil level and carry on
doing this each time it tries to resurface.
You must do something soon before the plant flowers and sets seed.
I actually like the stuff but I keep it in check by the second method.


Ok, thanks.

Actually I quite like it too, that's why it has got out of hand!!

Will try method 2!!

All the best.
