Overseeding a lawn is the act of sowing fresh grass seed into an existing lawn.

Lawns can become thinner, or gain an excess of undesirable grasses. An seeding treatment sows a preferential species of grass seed into the lawn. This will thicken the lawn and improve it considerable over the long term.

Sowing new grass seed can be as easy as just scattering new grass on the top. Ideally it should be combined with a scarification treatment to help to clean the lawn and prepare the soil surface for the new seed. Scarifying will improve the chances of the overseeding treatment being successful because seed needs contact with soil to germinate. Cleaning the lawn of thatch and debris helps expose the soil surface.
