Mechanical damage is probably one of the less common turfgrass challenges, but it can be significant and difficult to recover from when it occurs. A primary cause of this type of damage is lawn excavation for purposes such as underground utility repair and fence, pool or landscape installation. In each of these scenarios, the ground is disturbed. When this happens, turfgrass root systems are damaged, and often, the grass surrounding the excavated area can suffer damage as well.
Often when the material is replaced, clay and poorer quality soil is left as the topsoil and will need to be amended before it can support plant growth. Adding a nutrient-rich topsoil may be necessary if you plan to reseed or re-sod.
If heavy equipment is used, this can also lead to soil compaction in widespread areas, even those that weren’t excavated. Soil compaction can be relieved by lawn aeration, which will help your turf recover.
While it is best to avoid this type of lawn damage, there are solutions, and a turfgrass professional can advise you on the steps to recovering a healthy lawn.
