Aerating & De-Compacting Soil Around an Oak Tree

In this video, the soil surrounding the oak tree was badly compacted. When compaction occurs above the key structural roots of a tree, it diminishes the available soil pores (air spaces) that hold oxygen. This limits the oxygen diffusion rate in the soil and results in root suffocation. But a tree's roots must have oxygen in order to grow. As such, compaction can severely harm a tree. Aerating and de-compacting the soil in the critical root zone will fix the problem. As you will see in this video, we do so using an Air Spade. This tool blasts out air at over 1200 MPH. This is powerful enough to break up the soil, but does not harm the roots. Once the aeration is done, we cover the area with mulch. The mulch helps trap moisture, regulate temperature, and keep weeds and grass from growing.
