My garlic bed has been invaded by couch grass from next doors
field/garden. Given that the garlic is growing strongly, how best can I
get rid of the couch. I can not dig deeply to get all the roots out, nor
can I risk spraying with glyophosphate, especially as there is sometimes
stock in the field from where it came.

I spent the afternoon digging out as much as I could, but given the
growing plants I know I've not really done a good job.

Anyone any ideas?
