Hi Plot 52, Just to add to Charles’s sage words, I find that a good thick 4″ of woodchips on the paths means that when perrenials do pop up, the woodchip is so loose, the roots are easy to remove…
I feel your pain as I was used as child labout 50 years ago to grow potatoes for the family in a field of couch grass, where the rhizomes would go straight through the potatoes! I guess what I am saying is in the bit you are clearing, you may want to be thorough else you will be doing it next year again.
