Over time your soil naturally becomes compacted, leaving the subsoil undesirable for healthy lawn growth. Let Dynamic Lawn help with aerating your lawn to give it the vital oxygen it needs. Walking, playing, mowing, and watering compacts particles and reduces the air space necessary for root growth. Compaction is greatest in the upper 1 to 1 1/2 inches of soil and needs to be relieved by mechanical aeration. This mechanical process plugs 2-3 inch deep, finger size holes into the soil to improve the air, water, and nutrient exchange within your roots.
