Mulching or planting within the dripline of any shallow rooted tree should be done with care, focusing on the needs of the TREE. Suffocation can result if roots are unnaturally "buried." Mulching should be done lightly and kept from contact with the bark. Any ground covers planted in the root zone should be drought tolerant. Keep in mind that any trees growing in lawn will be forced to shallow rooting because of the way they are watered.
