I have great soil which is very easy to dig, sadly many trees have taken advantage of this - in some places I want to plant bushes or trees in gaps but everywhere It ry to dig appears to be solid root/stone (hard to tell when you can't see).
It is wonderful for ground matted with tendrils, or for roots up to finger thickness, but not so great for stones, hard ground or bigger roots.
What tools do gardeners use, either manual or powered, when they have to dig a hole (say up to 2 feet across and the same depth) which isn't making life easy? As a novice gardener I'm aware there might be whole types of tools I never even heard of! I suppose similar issues occur when trying to dig holes for fence posts.
