Dethatching also known as power raking is the mechanical removal of dead grass blades sitting under your grass known as thatch. Thatch is composed of both living and dead plant matter, and can prevent water, air, and nutrients from nourishing your lawn. Don't wait for your lawn to slowly suffocate!
A thick thatch layer is known to provide the perfect environment that can encourage pests and diseases. The process of dethatching is hard on turf, so the ideal time to tackle this chore is right before the lawn's vigorous spring growth cycle. Since the grass has not had a chance to come up yet, it will be easy to get at the thatch.
After the dethatching treatment, there will be quite a bit of debris on your lawn. This will need to be removed from the property in order to prevent it from further suffocating your lawn. Using a lawn vacuum will give the best chance of collecting as much thatch as possible.
Since dethatching is a stressful process for your lawn, you will want to follow it up with some fertilization and irrigation.
