Q.above the ground tree roots.
tree roots above the ground. What can be done about this problem.

If your tree is old, this is just part of a natural process - as the tree grows, the roots get bigger and come up out of the soil. If the tree isn't very old, it's probably a sign of thin topsoil. Although the tree might be more prone to falling over in high winds, it's really more of a cosmetic problem than anything. You can try adding a thin layer of topsoil and planting a groundcover like monkey grass to hold it in place and hide the roots, but it won't hurt the tree if you leave it as it is.
