I have a patio at the top and bottom of my lawn. The one nearest the house is about 3 inches higher than the one at the bottom. The lawn has a brick border. the border starts to rise higher that the lawn roughly 3 metres from the top patio. I want to raise the lawn to meet the higher patio following the profile of the border bricks. Should I till and reseed the area in question or can I topsoil and let the grass come through? Any help is appreciated.
Apply a general fertiliser at 100 g per square metre, rake in and wait a week. Then give a final rake over and sow new lawn seed.
