What happens if you don’t rake in grass seed?

What is the best topsoil for grass?
To get a healthy lawn, your soil will ideally be made up of a balance of sand, silt and clay. This is called loam soil. Loam soil holds moisture but also drains well when you water the lawn. It is able to retain nutrients and allow air flow, making it the most ideal soil for plants.
