Overseeding is a way of replicating nature. If we did not cut our lawns, the grass plant would naturally form seeds, and eventually the wind would carry them over the surface of the lawn. They will then lay dormant until the correct conditions allow them to germinate. This introduces new healthy plants to the existing lawn, helping to increase the quality of growth. We can replicate this process by ‘overseeding’. This can be carried out during Scarification, Aeration or Topdressing.
