Recently I had a very large spruce tree felled in my garden. It was too close to the house, blocked out loads of light and had massive knarled roots popping up everywhere in the lawn. I've decided to take out a flower bed nearby and lift some turf to create a gravelled area. However, I'm not sure how best to remove the roots before hiring a turf cutter. Some of them are quite thick so I presume the turf cutter wouldn't manage to go through them. Has anyone dealt with this before?
