Delayed reply but thank you all!
Resurrecting this thread as I've hit a snag. Due to weather, optimism, and being ill, I left the patch to see what would happen. The carrots and spring onions were sown 1st April and are still no-shows, so I decided to work on getting the couch out instead. In doing so I've discovered it's coming from the grass path beside the plot. Which I assume means that as soon as I get the patch out, it will come right back, since I can't dig up the grass path :/
Will a cardboard mulch have any effect against couch grass? I'm thinking of digging up this patch, laying cardboard at about 4 inches deep (covered in bed soil) with a shallower edge next to the path so that hopefully the couch goes under the cardboard when it comes back. Does that sound sensible or would sinking some kind of edge be better? Or both?
