The Benefits of Compost for Your Lawn

Compost, often described as "black gold" by gardeners, is a natural and nutrient-rich soil amendment. It is created through the decomposition of organic materials like food scraps, yard waste, and plant matter. Compost contains a wealth of nutrients and beneficial microorganisms, making it a valuable resource for enhancing soil quality and plant growth.

In this article, we will explore the question: Can you put compost on your lawn? We will delve into the benefits of using compost, the proper techniques for application, and how this practice can contribute to a healthier lawn and a more sustainable environment. 

So, if you've ever wondered whether compost could be the secret ingredient your lawn needs, you're in the right place. 

What Is Compost?


Compost is a natural and eco-friendly soil conditioner that gardeners and homeowners have relied upon for centuries. It is essentially the end product of the decomposition of organic materials. To understand why compost is a valuable addition to your lawn care routine, let's delve into what compost is and how it's created.

A Symphony of Decomposition

At its core, compost results from a carefully orchestrated process of natural decomposition. It starts with organic materials such as kitchen scraps, yard waste (like leaves and grass clippings), and other plant matter. These materials contain a mix of carbon and nitrogen, which are essential components for the decomposition process.

Microorganisms like bacteria and fungi primarily drive the decomposition process. These tiny creatures break down the organic matter into simpler, more stable forms. This breakdown not only reduces the volume of waste but also transforms it into a nutrient-rich substance that plants can readily absorb.

The Composition of Compost

Compost is often called "black gold" due to its rich, dark color and its exceptional qualities. Here's what you'll typically find in a well-made compost:

  1. Nutrients: Compost is a source of essential nutrients for plant growth, including nitrogen, phosphorus, and potassium. It also contains a range of micronutrients necessary for healthy plants.
  2. Organic matter: Compost teems with organic matter that improves soil structure, water retention, and aeration. This organic matter acts like a sponge, helping the soil retain moisture and nutrients.
  3. Microorganisms: Compost is a microbial hotspot, hosting countless beneficial bacteria and fungi. These microorganisms work harmoniously to break down organic matter and improve soil health.
  4. pH regulation: Compost has a natural ability to balance soil pH, making it suitable for a wide range of plants.
  5. Disease suppression: Compost can help suppress certain plant diseases, making it a valuable tool for organic gardening.
  6. Weed suppression: While not a guaranteed weed preventer, a well-maintained layer of compost can reduce weed growth.

The Composting Process

Creating compost involves managing the decomposition process carefully. Home composting typically involves layering organic materials, providing adequate aeration, and maintaining the right moisture level. Over time, these conditions encourage microorganisms to break down the materials, resulting in the creation of nutrient-rich compost.

Preparing Your Lawn for Compost

Before you start applying compost to your lawn, there are some essential preparatory steps to ensure that you get the best results. These steps will help you make the most of your compost application and ensure that your lawn receives the full benefit of this natural soil conditioner.

1. Soil Testing

Understanding the current state of your lawn's soil is crucial. Consider conducting a soil test to determine the pH level, nutrient content, and potential deficiencies. This analysis will help you decide on the type and quantity of compost to apply. 

2. Calculating the Appropriate Amount of Compost

Once you have the results of your soil test and the compost in hand, it's essential to determine the right amount to apply. Generally, a quarter to a-half-inch layer of compost spread evenly over your lawn is a good starting point. This thickness provides an adequate amount of organic matter and nutrients without overwhelming the grass. Once you are done spreading the compost, you should still be able to see the tips of the grass blades. Our lawn fertilization calculator makes it easy to determine how much Essential-G your lawn will need.

3. Timing for Application

The timing of compost application is also crucial. For cool-season grasses, consider applying compost in the early fall or early spring when grass growth is most active. For warm-season grasses, late spring is often the best time. Avoid applying compost during the hot summer months, as it may stress the grass.

4. Lawn Preparation

Before you apply compost, mow your lawn to a height of around 2 to 3 inches. This ensures that the compost will reach the soil surface and be in close contact with the grassroots. Remove any thatch or debris that may obstruct the compost from making direct contact with the soil.

By following these steps, you'll be well-prepared to apply compost to your lawn effectively, addressing specific soil needs and ensuring that your grass receives the full benefits of this valuable organic material.

How to Apply Compost to Your Lawn

Now that your lawn is prepared for the application of compost, it's important to explore the various methods for applying compost and the best practices to ensure even distribution. Choosing the right application method and technique will help you make the most of this valuable soil conditioner.
How to Apply Compost to Your Lawn

1. Spreading Methods

There are several methods for applying compost to your lawn, depending on your preferences and the equipment you have available. Here are three common techniques:


  • Topdressing involves spreading a thin layer of compost directly on the lawn's surface. This method is effective for improving soil structure and enhancing the health of your grass.
  • Use a shovel, wheelbarrow, or compost spreader to evenly distribute the compost across your lawn.
  • Aim for a layer about a quarter to a half-inch thick.

Overseeding with Compost:

  • Overseeding is a process where you sow grass seed in conjunction with the application of compost. This method is ideal for thickening your lawn and filling in bare spots.
  • After spreading the compost, distribute grass seed evenly over the area, then lightly rake the surface to ensure good seed-to-soil contact.

Aerating and Composting:

  • Aerating your lawn before applying compost can further improve the distribution and effectiveness of the compost.
  • Lawn aerators create small holes in the soil, allowing the compost to penetrate and reach the root zone more effectively.
  • After aerating, spread the compost evenly across the lawn.

2. Best Practices for Even Distribution

Regardless of the method you choose, it's crucial to ensure even distribution of compost to maximize its benefits. Here are some best practices:

Work in Sections

Divide your lawn into smaller sections to make the application process more manageable and to ensure that no area is overlooked. If you have a leveling rake, make passes in multiple directions to ensure an even spread.

Rake It In

Manually shovel or pour the compost over the lawn in snake-like shapes and then blend it into the grass using a leveling rake. If you have a vast area to cover, this may be backbreaking work, so using a broadcast spreader or topdressing machine is a better option.

Use a Spreader

Using a broadcast spreader or a specialized topdressing machine can help you distribute compost evenly across a larger area. These tools provide precise control over the amount and spread pattern. If you are using a topdressing machine, we recommend you buy CarbonizPN™ to topdress your lawn. If you are using a broadcast spreader, Essential-G™ is the best option for you.

Avoid Piling

Do not create thick mounds or piles of compost in one area, as this can smother your grass and hinder its growth. Even if there are areas of your lawn that need more attention than others, you should still aim for an even layer.

Water After Application

Check the label on your compost to find out whether you need to water your lawn straight away. CarbonizPN™ and Essential-G™ do not require immediate watering — wait until the rain comes or water in when you apply your granular fertilizer.

Monitor for Coverage

Walk your lawn to visually inspect for any uneven patches or missed areas. If you notice any inconsistencies, distribute additional compost as needed.
