Why Overseed Your Lawn

The first thing you need to understand is the purpose of overseeding. This is a process where you plant new grass seeds without removing grass or soil. Another benefit is, overseeding is used to cover barren or thin patches on your yard. Second, this is the fastest way to increase your grass density.

Third, overseeding can make your lawn look more attractive by adding new grass. Fourth, this process allows you to try different and better grass varieties.

How to overseed lawn without aerating

1. Choose the Grass Variety

Before overseeding, you must determine the grass seed you want to plant on the grass. To help you decide, you must consider the climate and location. If you live in the west, north and east the United States usually uses cool-season grass.

This is because the cool-season grass can flourish in summer being and also have a good tolerance for cold winter temperatures. Some cool-season grass varieties include fine fescues, perennial ryegrass, and Kentucky bluegrass.

People are in the south, southeast, and southwest in the United States should consider a warm-season grass. As the name suggests, these grasses can survive heat, especially during the summer. However, their disadvantage is that they cannot last long under freezing temperatures. Winter grasses include Bahia grass, centipede grass, and Bermuda grass.

2. Know When to Overseed

If you live in the northern region of the United States, do overseeding during the fall. This season is ideal because of suitable weather. The air cooled, but the soil was still relatively warm. More sunlight reaches the ground and trees shed their leaves.

In addition, during this fall weed growth was not explosive. So, there won't be much competition for new grass seeds. As for plant diseases, they will not be active enough to damage grass seeds during this period. Beside to autumn, you can do overseeding in the spring.

If you live in the south, you can do overseeding between the late spring and the middle of summer. The warm-season grass is more likely germinate and grow at an optimum level if the soil temperature is consistently warm.

3. Prepare the Soil

To prepare a soil bed for seedlings, you need not aerate it. First, cut the grass to make it as close to the ground as possible. Approximately, the grass must be in one to 1.5 inches from the ground.

Then remove grass clippings and debris from the surface so it will loosen the soil and helps more sunlight to reach the seedlings. You can rake it by hand or using a de-thatcher or a power rake.

4. Spread the Seeds

Next, spread the seeds, if the area is small you can spread the seeds by hand. Otherwise, you can use a broadcast spreader or drop spreader. To spread well on the lawn, mix grass seeds with sand. You can choose the same grass in your yard or you can try other grass varieties. The number of seeds you will plant completely depends on you.

5. Apply Fertilizer

After spreading the seeds, you must get a starter fertilizer 10-10-10. You need to apply two pounds of this fertilizer for every 1,000 square feet of grass. To help spread fertilizer evenly, you can use a metal rake. Raking it will help new seeds to have better contact and mix with the soil.

6. Irrigate Properly

It’s best to water two or three times a day rather than applying a heavier watering. If you water the area too much, the seeds can be dislodged or float in the water. When the roots grow, you can water them less often but let the water sink deeper into the soil.

It is too late to overseed your lawn once the growing season has passed.

For warm-season grasses, once the summer heat has arrived it is too late. The new grass will not be able to take root.

For cool-season grasses, late October on is too late to overseed. Again, wait until the next year for the best results.

Can you overseed without top dressing

Top-dressing a lawn can be great preparation for overseeding, but it's not necessary. You can also prepare a lawn for overseeding by mowing it at the lowest setting and bagging the clippings. After mowing, lightly rake the yard to expose and loosen the soil so the grass seed can make contact and take root. Otherwise break up the thatch layer with a power rake and remove the debris.


Overseeding is a way that can be done to improve health and grass density. You can overseed your lawn in any season, and it is possible to do it without aeration.
