Slice Seeder vs Overseeder – How Both Methods Differ 

What Is An Overseeder? 

What Is An Overseeder? 

The overseeder is utilized to oversee previously unhealthy or thin areas. An overseeder operates by spraying seeds from its container all over the lawn.

Typically, an aerator is used before an overseeder to drill holes throughout the grass, loosening the soil and producing microscopic holes where some of the seeds from the over seeder will fall into and boost their likelihood of germination.

Overseeders go through the soil without harm by using tiny teeth or spikes. These instruments create tiny holes into which the seeds fall, rather than a cut trench. If your lawn has unhealthy, thin-appearing grass, brown areas, or damage from disease, snowmelt, or insect infestation, you might need to employ an overseeder.

Pros And Cons Of Overseeder

An overseeder has benefits and drawbacks just like any other machine.


  • Utilizing it is less expensive.
  • Utilizing it with an aerator improves the soil’s ability to absorb nutrients and water.
  • Does not harm the grass


  • It is less successful since most seeds do not fall into the soil, leaving them exposed to birds.
  • The time it takes to get results is longer.
  • The use of an overseeder wastes seeds because more seeds are required.

What Is Overseeding? 

The most common tool used for overseeding is a broadcast spreader. The gardener either spreads seeds throughout the lawn with a spreader or by hand once the soil has been prepared for growing new grass seeds. The fact that some seeds won’t integrate correctly with the soil is a significant drawback.

You can have uncultivated grass areas on your lawn once more if loose seeds don’t germinate. However, carrying out two rounds of cross aeration before sowing the seeds will improve the likelihood of successful seeding.

How To Overseed A Lawn?

Using an overseeder on your lawn shouldn’t be challenging, although it is an expensive gadget.

You can operate the machine more effectively and offer your grasses the best chance of growing by using these methods:-

  • Use an aerator device to break up the dirt. Also, some seeds end up in the aerator machine’s holes.
  • Apply enough fertilizer to the grass to promote growth. The majority of grasses will fall to the ground, thus it needs adequate fertilizer to speed up their growth. Be careful not to overfertilize the grass and burn it.
  • To ensure germination, water the soil every day. For the seeds’ roots to grow, sufficient irrigation is required.

Pros And Cons Of Overseeding


  • Causes no de-structuring or shifting of the soil.
  • Excellent for rejuvenating mowed grass and brown grass growth
  • Fit for the fall when the weather is cool and the soil is warm; grows stronger roots
  • Gardeners that desire thick grass might perform this action following slice-seeding.
  • A simpler procedure with a lower likelihood of mistakes


  • The seeds are quickly displaced by domestic animals, wildlife, foot activity, excessive wind, and water.
  • Incorrect seed distribution might result in unsightly grass growth.
  • Low germination rates are caused by seed displacement brought on by exogenous influences.
  • No of the season, you will need to increase the watering frequency.

What Is a Slice Seeder? 

What Is a Slice Seeder? 

A tool that can be used to plant seeds in rows is a slice seeder. These tools come in various sizes and are suitable for residential and agricultural use. Depending on how much area you have to work with, you may either utilize them by hand or install them onto a lawn tractor or agricultural tractor.

A slice seeder can be employed on freshly plowed ground or bare ground. The machine has blades installed that can cut through dirt at different depths and distances apart. Quickly digging shallow trenches can be used to plant seeds for other plants, grass, or vegetables.

Slice seeders, also known as slit seeders, enable you to sow seeds that are in perfect touch with the ground. You can adjust the height to the height advised for planting.

The seeds will be dropped into the ground after a furrow has been made, and another device will hammer the seeds into the soil. Doing this can increase the likelihood that your seeds will germinate successfully and be completely covered in dirt. Birds and other animals won’t consume the seeds since they are buried deeper in the ground and covered by the earth.

Pros And Cons Of Slice Seeder


  • Since the seeds are planted directly in the soil, it is more successful.
  • Aids in soil thatch removal
  • Conserves seeds in the form of a slice. Less seeds are used per square inch by the seeder.
  • Results appear more quickly.


  • It requires a lot of capital.
  • Possibly destroying other ground grasses

What Is Slice Seeding? 

Slice seeding is carried out using a piece of machinery called a slit seeder or slice seeder. This method of sowing seeds is regarded as being very trustworthy. To cut through the earth, the equipment essentially employs steel blades. Slice planting has the benefit of ensuring that seeds make optimal contact with the soil.

The blades can be moved in accordance with the advised seed planting depth. Gardeners may anticipate an even planting bed because a machine cuts the dirt into little pieces.

The seeds are thrown onto the soil after the soil slices are complete, and the soil’s teeth pound the seeds into the ground. Some jurisdictions have outlawed the sale of seeds due to the current status of the world. It would help if you were careful not to affect your current supply.

How To Slide Seed a Lawn?

Here are some simple methods for overseeding grass with a slice seeder. Even if you hire specialists, it is advised to undertake basic pre-planting methods to offer your grass the best chance to develop.

  • Choose a machine that deposits the seeds before forcing them into the ground with its blades. Avoid choosing a machine that forces the seeds into the ground first.
  • One set of seeds should be applied in rows parallel to your mowing lines, while the other set should be applied perpendicular to the first seed rows.

Pros and Cons of Slice Seeding


  • Earth with grooves for ideal sowing locations
  • Earth with grooves for ideal sowing locations
  • 60% faster than average grass seed germination rates
  • Protects seeds from being damaged by birds, wild animals, excessive wind, and water.


  • If not properly stored, blades may rust. need weatherproof garden shed storage
  • Shoots may clog, and fungal development may increase.
  • Capability to damage lawn surfaces and soil texture
  • Weeds will spread internally if they are not removed first.


Since both products have advantages and disadvantages, as you can see from this article, it is up to you to choose which is ideal for your unique circumstance. While an overseeder makes these trenches with tiny teeth or spikes, slice seeding requires cutting them with a blade. An overseeder can be all you need if you don’t have a huge area to seed. A slice seeder, however, can be the ideal option if you have a large lawn and don’t mind spending a lot of money.
