I sort-of built up beds around a lot of our trees. I didn't use soil, however, as it's said to smother the roots of the tree. I just laid out a couple of inches of compost and let the worms take it from there. Each year I add more compost, whenever I have it to use. I've pretty much limited my under-plantings to things that don't require a rich soil...just in case. Trees and plants seem to do well together here, as long as compost is replaced as it disappears.
