Cut the grass growing. Trim so that the grass is only about 2.5 - 4 cm high to limit competition of the growing grass. The mowing also helps keep the seeds from getting stuck between tall grass, and also allows sunlight to shine on young grass growing trees.

Remove litter and trimmed grass. The litter is mostly dead organic matter lying on the ground. You should also remove freshly trimmed grass chips. The litter or debris will prevent the seeds from sprouting, as the seeds need to come into direct contact with the soil to germinate.

Use a rake to gently scrape the surface soil. This process is called "litter cleaning." If you don't have a special rake used to rake the straw, you can use a rake to remove the leaves, though it may take a little harder work.
You can rent gasoline-powered rice straw rakes at tool rental services. This will save you a lot of time and energy.

Loosen the soil using suitable methods, depending on the soil compaction. Options to loosen the soil include rotary tilling, aeration, deep plowing, or using a straw rakes.

Although using a rotary tiller is a popular method when sowing seeds in new grass, it also comes in handy when sowing additional seeds. The only difference between the additional seeding and the before planting the new lawn is depth: additional seeding only needs to be about 2.5 - 5 cm deep, while planting a new lawn requires cultivate 10 -15 cm deep.
Aerate the soil with a tiller, be careful not to break the structure below the ground too much. Groundbreaking can damage growing grass roots and give weeds a chance to invade.
If the area to be cultivated is too large, consider renting a gas-powered ground aerator.

Part 2 of 3: Soil preparation

Check the pH of the soil. The ideal pH is between 6.0 and 6.8. If you don't know how to test your pH, you have two options:
- You can purchase a pH test kit to test yourself according to the instructions on the package.
- You can hire an expert or ask your local agriculture department to try it out for you.
- While this step doesn't have to be done when sowing complementary seeds, it can make the difference between success and hard work on the other side. It can be risky to skip it, but usually it's fine in the long run.
Add lime to the lawn if needed. Lime will help balance the pH if needed. Carefully follow the instructions on the package to determine the amount of lime to be added based on pH and the area of the lawn.
Spread an extra layer of compost onto the ground. You should spread a thin layer of fertilizer on the lawn. The fertilizer will help the seeds germinate and provide more nutrients for the seeds to grow.
- Spread a layer so thin compost over the entire grass surface. Better to fertilize than excess. If too much fertilizer is applied, the growing grass will be buried under the fertilizer and die.
- Using a rake to spread the compost evenly over the entire grass surface, it is best to use a specialized rake to rake the straw. Make sure the compost does not fill the tops of the grass. Remember to scratch lightly when spreading compost.

Part 3 of 3: Sowing seeds and nourishing grass seeds

Spread grass seeds evenly over the entire lawn. Use the amount of seeds on the package depending on the area of the lawn. To sow seeds, you can use a rotary or spreader, a manual sowing machine, or spread the seeds with your hand.
- Be sure to choose a grass seed that is suitable for the type of grass currently growing on the lawn. Bermuda grass is very beautiful, but probably not suitable for buffalo-tailed grass.
- It is best to stay away from inexpensive grass seeds. Remember the phrase "You get what you pay for". If you're too frugal, your lawn can reveal it.
Gently rake the area where the seed was sown to help bury the seed in the ground. Remember that grass seeds that are not in contact with the soil will not germinate.
Apply nitrogen fertilizer that dissolves slowly. Make sure to use fertilizers suitable for the specific conditions of the lawn according to the results of the soil samples.
- Spread a thin layer of compost over the seeds. Use the bottom of the rake to gently pat the fertilizer.
Wet the entire lawn immediately after sowing additional seeds. Continue watering regularly, 3-4 times a day for at least the first few weeks to make sure the seeds sprout - it's essential to keep the seeds moist. Never let the seeds dry completely. Once the seeds have taken root, you can water less.
- In the first phase, you should keep the seeds moist almost continuously around the clock. This will help the seeds sprout. Once the grass has sprouted, a lot of watering will actually kill the young grass.
Apply nitrogen fertilizers that dissolve quickly. Use a quick-release fertilizer at a rate of about 0.45 kg for an area of about 100 square meters of grass after 5 weeks of germination. Six weeks later, sprinkle another layer of the quick-release nitrogen fertilizer.
- Do not use too much nitrogen fertilizer. Too high a nitrogen content in the soil can ignite newly sprouted seeds and young grass.
Cut the grass when the grass is 5 -7.5 cm tall. Keep trimming the grass so that the grass is only about 5 cm tall throughout the season. advertisement

Advice

Once the seeds have been sown and watered, don't let them dry out. Freshly sown grass seeds need to be kept moist until germination.
You can rent the necessary equipment for aeration and / or aeration at equipment stores and rental services.
Do not let humans and animals walk on the grass that has just been sown until new grass grows.
Tilling will allow the compacted soil to break down, allowing the soil to absorb oxygen, water, fertilizers and minerals. However, grass seeds that fall into the vents will not germinate well, or will not sprout.
You can buy a cheap soil test kit or get a free soil test and analysis kit. Contact your local government, gardening center, university extension services or gardening programs for information about services in your area.
The longitudinal blade mower, also known as the seeding machine, also loosens the soil by creating longitudinal grooves, increasing the number of grass seeds in contact with the soil. When using this type of machine, it is recommended that you run the machine two to three times in different directions to create diagonal cells for increased coverage.
