I built a raised bed last year 8ft x 4ft x 18" and filled it with a mix of soil and peat. I have turned the soil over and started planting a few veg. What I have noticed is there are no worms in the soil. Which is the best way to get worms into the raised bed(this bed is built onto a concrete base),Or do i not need to have any worms in the soil
