I always hesitate using the no dig method, because of the heaps of material one has to buy. and at least in winter I prefer to sow directly. And I think at in suburban gardens one should over once, because of the things you dig out: old batteries, tubes, asbestos sheets, big stones etc. On the other hand side mulching is quite good for bigger plants and if not planted too densely. Who grows green manure in a small suburban garden? Do you slash it dig it under or hoe it? Who uses strictly the no dig method? Do you even not hoe? How do you prepare a seedbed? Who uses mixed methods? and in which climate does no dig best? And: has the no dig method roots in some sort of traditional agriculture maybe in he tropics?
