While consistent watering and fertilization are important for sustaining a healthy lawn, grass also needs plenty of air pockets in order to breathe and absorb water and nutrients. Over time, regular traffic, play, and sports activities can cause soil compaction, limiting the amount of water, air, and nutrients that reach the grass roots. In the core aeration process, our machine removes soil cores to reduce compaction so that oxygen, water, and fertilizer can more easily penetrate the soil.The process of aeration is perforating your lawn with small holes to allow nutrients, water, and air to reach the roots of your grass.
