At one location I was going to arrange for putting in mulching for a line of trees along a road. The soil around them is pretty compacted, and is what we call "decomposed granite". It packs in pretty good.

These trees are only a couple years old. I'll find out the types and take pictures in the next couple days.

The question, is how do you take out compacted soil around the base of the trunk, in order to put mulching in around it? You'd use one of these air spades?

I was considering doing something with high pressure water, set a little tent around it to reduce splatter, dig for drainage. You might not be able to do that in some locations, but here I can. Would the Air Spade be better for this, or would high-pressure water work too?
