Lawn aerating is the process of removing small soil plugs from your lawn to encourage more oxygen to reach the roots. This promotes great root growth, helps dead grass decompose faster, and makes your lawn more drought resistant. Aeration also helps break up our heavy clay soils creating an easier growing medium for lawn roots. When lawn aerating and Fescue over-seeding are performed at the same time the seed also drops down into these little holes into a cooler, moister area that germinates much faster and healthier. Artworks Lawn Care typically starts scheduling this lawn service for September through October for Fescue lawns.
