I made a useful discovery today. I noticed some of the troublesome grass path between two of my beds had started to tumble over the edge and onto one of the beds. I started to just pull up the grass clump. As it came away, it pulled more of the matted grass roots with it, like a green carpet. I continued and found that, in fact, a lot of it would come away as simply as pulling up a roll of thick muddy carpet. I soon found myself stripping away the full length of the one path and lugging it into a barrow.
Well, I have a work day tomorrow so I can always rest at my desk until my back and knees forgive me. At least my fingers won’t be on display so much. Yes, tearing up two barrows full of muddy root matting does get the soil under the nails pretty deeply!
