Soil compaction under and around our trees in the heavy clay soils of Bucks and Montgomery County is a big problem. Over time, soil and mulch can build up around the base of trees, covering their root flares. This can cause a great deal of stress, often leading to insect infestation and disease. Buried root flares also promotes girdling roots, which leads to the decline and often death of trees.
Excess soils should be removed from the root flare of trees, however it must be done carefully so as not to damage the root system. Our certified arborists at Plant Health Solutions use pneumatic air spades to remove excess soil with the least amount of root damage. Pneumatic air is used to fracture and aerate heavy soils and allow better air and water circulation in the soil around the tree. Once the appropriate amount of soil has been excavated, the crew will begin to remove any existing girdling roots. Organic material will then be incorporated into the existing soil of the tree root zone.
Pneumatic air removal of soil can be highly beneficial for the overall health of trees that were initially planted too low or now have compacted soil built up around the base of the trunk. It also relieves compaction due to construction or foot traffic, poor soil structure and over watering. And again, it also gives the arborist a chance to discover and remove damaging girdling roots.
