Even as the temperature drops the grass on your lawn keeps growing and won’t go dormant until the ground freezes. Because of this, it’s important to keep mowing your lawn as you usually would until the first freeze. Seeding, fertilizing and aerating your lawn are also crucial tasks to complete before the first freeze when your lawn goes dormant. Aerating, whether plug or slashing, helps create channels for nutrients, water, and oxygen to get to the lawn’s roots. Once aerated, spreading fertilizer will help the grass grow healthy and thick in the spring. After aeration, overseeding establishes growth to help problem areas in your yard.
