Below is a procedure for overseeding centipede grass with fescue/zoysia grass:

Before we get to the steps you’ve to follow, you must assemble the right tools for overseeding your centipede grass with fescues and zoysia. These include a lawn rake, fescues/zoysia grass seeds, seed spreader, dethatching rake, water hose, lawnmower, lawn roller, high-phosphorous fertilizer, and gloves.

Steps on How to Overseed Centipede Grass

Step 1: Prepare The Lawn For Overseeding

The first step is to prepare the lawn for overseeding. Start by watering the grass lawn properly a few days before overseeding. Remove any weeds on the lawn using a hand and mow the lawn low. Next, rake up and get rid of the grass clippings and other dirt on the lawn. Measure the area you want to overseed and purchase the right amount of fescues seeds you want to spread.

Step 2: Dethatch The Centipede Grass

Split up the layer of thatch, living and dead grass stems, leaves, and other plant parts piled up between the soil and the bottom of the grass. You can dethatch the grass using a dethatching rake if it is a small area. But if you’re dethatching centipede grass in a larger area, use a vertical mower.

It will make your work easier and will dethatch the grass quicker. But if you can see the soil surface when you look down the grass, there is no need for dethatching your lawn.

You can proceed to the next step.

Step 3: Aerate The Lawn

After getting rid of the weeds, dethatching, and readying the fescues seeds, the next step is to aerate the lawn. Aerating the soil will provide a conducive environment for the seeds that are yet to be spread to flourish. Aerated soil has two vital gases (oxygen & carbon dioxide), which the fescues seeds need to germinate.

It is important to aerate your lawn if it has compacted soil. But if the soil is loose and well-moist, you don’t need to aerate it. Also, aeration helps in removing any buildup of thatch.

Step 4: Disperse Fescue Grass Seeds

Next is to spread the fescues grass over the prepared area using a seed spreader. Disperse the right amount of seeds per square foot. You mustn’t disperse many seeds in one area of your lawn. Even though not harmful, you should try and disperse the seeds evenly.

Besides, overseeding is different from seeding. Thus, you should spread half of the grass seeds you could’ve seeded on a bare lawn.

And if you have bare areas or brown patches, you can add up the number of seeds you spread.

Step 5: Rake The Seeds

When you’re satisfied with how you’ve spread and dispersed the fescues grass seeds, you can cover them now. Use a rake to cover the seeds with soil. This is vital as it helps the seeds to be in contact with the soil and ready for germination.

To ensure that the seeds have settled in the soil, water the lawn for around 5 to 10 minutes. The soil will be moistened, and the seeds will settle in the soil, ready for germination.

Step 6: Fertilize The New Seeding

Finally, apply the right fertilizer to boost the growth of your fescues grass seeds. Use a nitrogen fertilizer, which will also help to green up the centipede grass. Avoid using weed-and-feed fertilizers that cause more problems instead of supporting your grass.
