A: Surface roots like those seen in the picture can cause many problems in your yard. They can be a trip hazard, mowing hazard, cause driveway and foundation damage and make your property look unkept.
Usually, surface roots are cause by compacted heavy soils which are common in Southern Louisiana. The heavy soils do not allow for the passage of air and oxygen. Tree roots are like lungs, they need oxygen to be healthy. Many root functions are accompanied by the exchange of gases. If roots are unable to do this exchange under the ground, they start to grow towards the surface. Very healthy trees can have surface roots.
The problem with surface roots for the tree is that they are exposed to mechanical damage which can lead to fungal or bacterial infections. As surface roots are constantly nicked by lawn mowers and weed trimmers, the tree must extend energy to seal the wounds. The energy is diverted away from some other process and can lead to tree decline over time.
Bob’s Tree Preservation is able to help reverse soil compaction with the incorporation of Eco-Mulch and aeration of the soil around the surface roots.
A root barrier might also help in protecting your hardscape (driveways, sidewalks, patios, pool decks or foundations). Bob’s Tree can install Biobarrier which is guaranteed to last for 15 years for your peace of mind.
