Core Aeration: The process of mechanically removing small plugs of soil and thatch from a lawn to alleviate soil compaction and improve air, water, and nutrient flow to the roots.
Soil Compaction: The state where soil particles are pressed together, reducing pore space and restricting the movement of air, water, and roots.
Thatch: A layer of living and dead organic matter, such as grass stems and roots, that accumulates between the soil surface and the green grass blades. A thick thatch layer can block essentials from reaching the soil.
Cool-Season Grasses: Turfgrass varieties, like Kentucky bluegrass and fescue, that grow most actively during the cooler temperatures of fall and spring. They are common throughout Idaho.
Overseeding: The practice of spreading grass seed over an existing lawn to fill in bare spots, improve turf density, and enhance its color and vigor.
