Q.landscaping a circular driveway
We previously had a large magnolia tree in the center of our circular driveway. Over time, the roots grew so much that they lifted and cracked the driveway. We have now removed the tree and had the driveway repaired; however, we now have a bare 30-foot-across bare spot in the middle of the driveway. We live in Virginia Beach– what kind of tree would be decorative for the center of this area, but will not impact the driveway?
