How to Decompose Grass Clippings Fast – Leaf Decay

Grass clippings are one of the best things you can do to your lawn. They’re free, and they give your lawn a natural fertilizer. However, if you let them sit around, they will begin to decompose and release all those nutrients back into the soil. If you’ve ever taken the time to bag up your grass clippings, you’ve probably noticed that they’re not exactly a fine powder. They’re chunky and wet — not exactly the best combination for decomposition.

Best Nitrogen Source

Grass clippings are the best nitrogen source for your garden. You can leave them on top of your soil or compost them to speed up decomposition.


The main benefit of leaving grass clippings on top of the soil is that they act as mulch, which helps retain moisture and prevent weeds from growing. However, if you leave them on top too long, they will start to break down and become a slim mess that will inhibit root growth.

Easy Ways


Use Push Mower

Use a push mower, which produces less waste than a reel mower. If you have more than one acre of lawn, consider renting a riding mower instead of a push mower.

Mow Thrice a Week

Mow at least three times per week while your lawn is actively growing in spring and summer to prevent it from becoming too long and thick. This will save you time when you have to rake up all those leaves!

Mow Before 9 AM or After 5 PM

Mow before 9 am or after 5 pm so that moisture doesn’t build up in your lawn overnight and cause mold or fungus growth on your grass clippings.

Rake Up

Rake up all the clippings from your lawn after mowing.

Spread out on the lawn

Spread out on the lawn

The most obvious way to get those clippings to break down is by leaving them where they are. This is the easiest option if you have enough room in your yard. Just spread out your grass clippings and let nature take its course.

Add grass clippings to the compost pile or bin

If you don’t have enough space for all of your grass clippings, then consider adding them to a compost pile or bin instead. This will help speed up the decomposition process because it’s an aerobic environment (oxygen-rich).

Use as mulch

Grass Clippings don’t decompose quickly. If you pile them up, they will rot and smell bad. The best way to dispose of grass clippings is by mulching them into the soil with a mower deck attachment.

Mulch Mower

The problem with this method is that it’s hard work. A better option is to use a “mulch mower” that shreds the clippings into very small pieces before depositing them onto the ground. This makes it easier for soil microbes to decompose without causing an odor problem like rotting leaves in compost piles or trash cans.

Animal Feed

Use grass clippings as animal feed. Grass clippings make great animal feed for chickens, goats, and cows. They’re high in protein, making them an excellent source of nutrients for livestock.

Turning Clippings into Compost

You can speed up the decomposition of grass clippings by turning them into compost. This is the best way to recycle your lawn waste and add nutrients to the soil.

The process for making grass clipping compost is simple, but it does take some time. The process can speed up by shredding the grass clippings before adding them to your compost bin or pile. Shredded clippings will break down faster because they have more surface area exposed to air and moisture than whole clippings.

Ways to Make Compost

Compost Heap Yourself 

Step 1

Collect the grass clippings from your yard mower or trimmer. You’ll need about 2 to 3 pounds per square foot of your compost heap. If you have more than one person contributing to the compost heap, weigh each person’s contribution separately and add them together to get your total weight.

Step 2

Create a base layer with newspaper strips or cardboard boxes to prevent the grass clippings from drying out too quickly as they decompose. This will also help keep the heap from shifting while it works its magic.

Step 3

Layer alternating layers of grass clippings and brown materials such as leaves, straw, sawdust, or wood chips until the whole area is covered by at least 4 inches of material.

Compost them with Greens

Compost them with Greens

Greens are a great way to add nutrition to your compost pile. It consists of kitchen scraps and green leafy vegetables like lettuce, spinach, and kale.

Here’s how to compost grass clippings with greens:

  1. Collect your grass clippings in a plastic bag or container and place them on top of the kitchen scraps in your Green Bin.
  2. Close the lid tightly so that no odors escape from the bin, allowing air to circulate inside it. The more air you allow in the container, the faster it will decompose.

Compost Accelerator

How Does Compost Accelerator Work?

Compost accelerators (also called humic acids) contain naturally occurring organic compounds that help microorganisms break down organic matter faster than they normally would.

How Do I Use Compost Accelerators?

It’s easy! Just sprinkle the accelerator over your grass clippings before adding them to your compost bin or pile. You can mix it with other materials in the container if you prefer not to sprinkle it on top of everything else.
