When using the no dig gardening method with mulched vegetable beds, what do you do in fall with the old plants?
I know that in no dig you do not want to disturb the soil. Also when mulching it's best to leave the mulch at the surface.
But now it's autumn and I have to take out some annual vegetable plants. Some of them are quite big and have developed large root systems. When I pull them out a lot of soil comes away with the roots and some mulch gets mixed inside the newly created hole.
Should I keep uprooting or should I just cut the stalks where they meet the ground?
That seems less disturbing to the garden bed, but with some big plants it's leaving a lot of big hard roots in the ground. Since the ground is frozen in winter where I live I don't know if they will have time to rot down.
