We have this stuff - and nettles - invading from the neighbouring fields. I use glyphosate along the boundary on the field side of the fence to try and weaken it but on our side I have too many treasures from fruit bushes to strawberries and perennial flowers and shrubs that I can't risk so just have to do constant weeding.
A fork is better than a hoe or spade as it breaks up the roots less and leaves fewer voluntary cuttings to regrow. 2 years of this regime has led to a significant reduction on the veg plot and garden side. Onwards and upwards this year.
Glyphosate kills couch very well and couch can easily be completely and permanently killed when it is open to spraying. It is much more of a challenge when growing intermingled with plants but under the canopy of shrubs, for example, is easy to selectively spray.
There are two secrets.
1.The couch needs to have had chance to make a good top of green leaves to drink up the weedkiller
2. The couch needs to be intact as a plant. Lots of little pieces chopped up by cultivation are not sufficiently exposed on account of erratic regeneration from each 'root' (rhizome).
Digging it out by hand (which I do every year) is very very satisfying though.
Covering it up with black polythene is wat I am trying this year. The couch grass is growing in my asparagus plants and very difficult to get at. I covered the clumps with cut-up potting-soil bags and when the asparagus starts growing I will cut small holes in the plastic to let them through. I hope this works!
I am not using the round up gel on couch grass in the lawns and flower beds. Works a treat and doesn't crest large dead patches or touch the plants.
Meant to say now using roundup gel
