Doing a lawn job involves several steps. The first step is to EDGE the lawn, which means to trim the grass along the edges of the lawn and around obstacles such as trees and flower beds. This is done with a tool called an edger. The second step is to AERATE the lawn, which involves making small holes in the soil to allow air, water, and nutrients to penetrate the grass roots. This can be done with a machine or manually with a garden fork. The third step is to resod the lawn, which means to replace the existing grass with new SOD. The fourth step is to SOD the bare spots, which means to fill in any areas that are not covered with grass. Finally, the fifth step is to reseed the lawn, which means to spread grass seed over the entire lawn to help promote new growth.
