How can I effectively dethatch zoysia grass in my lawn?

To effectively dethatch zoysia grass in your lawn, you can use a dethatching rake or a power dethatcher to remove the layer of dead grass and debris that has built up. Make sure to dethatch when the grass is actively growing and water the lawn before dethatching to soften the soil. After dethatching, you can overseed and fertilize the lawn to promote healthy growth.
