Im building raised beds and
im putting in soil and a bit of compost mixed. I am going to top it with a mulch of shredded leaves and some grass clippings. I put the beds on top of the ground with the turf off. If I want to bring worms up to start working the hard soil underneath what would you suggest to help it along? I was thinking maybe trying some with cardboard on top of my fresh soil/compost then the grass and leaves on top, would that work?
