Can I add my tuppenceworth, although it may not be to everyone's liking? Glyphosate the bl**dy lot, once will sort out the couch grass, roots and all (and all the other weeds), and once the dead grass is dug in it can be planted up immediately.It's all very well towing your guts out to remove it manually, but this is the quick fix.Of course, it's not organic, but faced with that situation, it's what I'd do.
No, it's definitely not wise as you'd probably be creating a reservior of couch. Get rid of the grass, then if you want grass paths, seed them and be patient.
