Centipede grass is a warm-season and heat-tolerant grass. The grass is native to Southeast Asia, and it can reach heights of up to 3-inches. This grass is also easy to maintain and a favorite for many homeowners and gardeners in the southern parts of the US. The grass can be planted through sod, seed, or even springs.
On the other hand, the fescue grasses are shade-tolerant cool-season grasses that also grow exceptionally well in the southern US.
This grass grows smartly during cold spring and fall months. In comparison, the zoysia grass is widely grown in Australia and Asia. It is an ideal grass for lawns and does well in warmer climates.
If you’ve centipede grass that is patchy or with bare spots on the lawn, you can overseed it with fescue or zoysia grass as the warm season comes to an end.
Overseeding centipede grass with fescue or zoysia grass will improve the appearance of your lawn. Besides, centipede grass is easier to maintain, unlike other types of grass. But when it gets cold, this grass may struggle, and that’s why you need to overseed it and protect it from the cold winter season.
Below is a procedure of overseeding centipede grass with Fescue/Zoysia grass:
Before we get to the steps that you’ve to follow, you need to assemble the right tools for overseeding. These include lawn rake, Fescues/Zoysia grass seeds, seed spreader, dethatching rake, water hose, lawnmower, lawn roller, high-phosphorous fertilizer, and gloves.
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 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 that you want to overseed and purchase the right amount of fescues seeds that 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 that have piled up in-between the soil and 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 using 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 are needed by the fescues seeds to germinate.
It is important to aerate your lawn if it has compacted soil. But if the soil is loose and well moist, then there is no 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 feet.
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 that you could’ve seeded on a bare lawn. And if you have bare areas or with brown patches, you can add up the number of seeds you spread.
Step 5: Rake The Seeds
When you’re satisfied with the way you’ve spread and dispersed the fescues grass seeds, you can cover now. Use a rake to cover the seeds with soil.
This is vital as it helps the seeds to be in contact with 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 will cause more problems instead of supporting your grass.

- After the fescue or zoysia seeds germinate, water them at least twice a week. It is recommended to water the lawn in the wee hours of the morning.
- Apply the right type of fertilizer after the seeds have sprouted. It is ideal for fertilizing your lawn after the grass has sprouted. This should be done after four weeks and repeated after every six weeks.
- Keep your kids and pets away from the lawn when mowing. You don’t want to risk any injury or accident as you work on the lawn.
