When to Dethatch

The best time to dethatch is in the late summer or early fall. That’s when your grass is growing most vigorously. Before dethatching, mow a little shorter than normal. You will also achieve better results if you do it after light rain or watering.

Aerating

Aerating and coring are two different terms you might come across while preparing for lawn maintenance. An aerator pulls plugs out of your soil. This helps to loosen compacted soil and allows air and water to reach the roots. Aerating is considered a better way to dethatch your lawn since it puts less stress on it.

When to Aerate

As with dethatching, you want to aerate when your grass is at its peak growing season – late summer or early fall.
