How can I effectively patch grass repair in my lawn to restore its lush and healthy appearance?

To effectively patch grass repair in your lawn, start by removing any dead or damaged grass. Loosen the soil in the patch area and add a layer of topsoil. Plant new grass seeds or lay down sod, making sure to water regularly and keep the area moist until the grass is established. Fertilize and mow the new grass as needed to promote healthy growth and restore your lawn's lush appearance.
