Surface Tree Roots
Surface tree roots can be a problem to mow around for many homeowners.
However, a walk through the woods should convince anyone that surface roots
are a natural phenomenon. Growing surface roots is part of the normal growth
habit for many trees, like Silver and Norway Maples as an example.
Mower blades can be damaged when striking surface roots. This type of damage can be very bad for the tree, as well. Open wounds may allow disease and insect problems to infect the tree.
Roots serve many purposes. They anchor the tree to keep it standing upright and take in water and nutrients. Roots must have an adequate supply of oxygen in the soil to be healthy. By growing at or near the surface, roots are able to supply the tree everything it needs to remain healthy.
Cutting and removing surface roots is not a good option. This practice weakens the tree. Recovery from this type of damage can take years, if the tree recovers at all.
Another option considered by many people is to put a layer of soil over the offending roots and seed with grass. This can cause the health of the tree to decline. It is also just a temporary solution, since roots will resurface. It is a good idea to have an arborist check the site before adding any soil to the area.
Since grass does not grow well in the shade of trees anyway, perhaps the best option is to eliminate mowing in the area altogether. This can be accomplished by spreading a mulch under the tree. A three-inch layer of shredded bark or wood chips work well. For added interest, shade tolerant ground covers can be used. There are hostas and many other shade-loving flowers that will add an interesting focal point to any landscape.
