I was told to cut down the top growth then:
B) Fork it all out and compost it (which is what I've been doing slowly)
I plan to mulch the areas I have dug to prevent re-growth, and I expect to hoe the ones that have escaped. I think there will be years of seeds in the soil. In my plot the soil beneath the grass was compacted, so at least the initial digging helps the compaction and aerates the soil?
I have to say our new couch plot was not nearly as bad as our rubble-strewn, back breaking, bramble patch (where herbicides did look rather tempting.......what a dilemma).
I'd like a scythe asap as that grass is going to keep growing.........and maybe one of those azadas - followed by a no-dig approach
