The dethatching process removes the excess thatch and ensures that only a healthy layer remains on the surface. Aeration Process – Your lawn's soil can become compacted over time due to pressure, weight, and gravity. This can make the surface hard, which can compress the roots and stifle them.

Is it better to dethatch or aerate?

A dethatcher works well when you have a lot of dead grass on top of the soil, making the lawn feel spongy. An aerator is best used when the core has a thick layer of thatch, usually more than 0.5 inches.

Do I need to aerate my lawn after dethatching?

Aerating is best done right after dethatching, preferably in the fall following a complete growing season. This gives the grass time to fill in and 'recover' after removing the soil plugs. The type of grass you have and the climate in which you live also determine when to dethatch and aerate as well.
